Answer:

w = 5.3311 rad/sec

Explanation:

n = 100 has a k = 540 N/m

k depends on the number of coils by:

[tex]k = \frac{G*d^4}{8*n*D^3}[/tex]

By the design equation we see that the spring stiffness k has an inverse relationship with number of coils n.

Hence, when n = 25 coils ; k = 4* 540 = 2160 N/m

The relationship between angular frequency and k is:

[tex]w = \sqrt{\frac{k}{m} }\\\\Hence,\\\\w = \sqrt{\frac{2160}{76} }\\\\w = 5.3311 rad/sec[/tex]

The angular frequency is approximately 5.34 rad/s.

To determine the angular frequency of the motion, we need to follow these steps:

Calculate the spring constant of one of the 25-coil springs.

Since the original spring has 100 coils and a spring constant of 540 N/m, the spring constant of one 25-coil spring, k(short), is:

k(short) = 4 * k(original) = 4 * 540 N/m

k(short) = 2160 N/m

Calculate the angular frequency, ω, using the formula:

Where:

Thus,

The angular frequency of the motion is approximately 5.34 rad/s.

With the meter rule the boy can measure the total distance travelled by the cart by application of a constant force.

With the stopwatch he can measure the time it took the cart to cover that distance.

Explanation:

Knowing the distance covered by the cart and how long it took to cover that distance, the equation of constant acceleration motion can be used to find the acceleration of the cart during that motion.

S = ut + 1/2at²

S = distance covered

a = acceleration of the cart and

t = time taken.

The student can measure the acceleration of the cart and the total distance traveled to determine the inertial mass of the cart.

The student can measure the acceleration of the cart while in motion by using the stopwatch and the meterstick. They can measure the time it takes for the cart to reach a certain distance and calculate the acceleration using the formula a = (vf - vi) / t, where vf is the final velocity, vi is the initial velocity (which is zero in this case), and t is the time taken.

The student can also measure the total distance traveled by the cart after it has been in motion using the meterstick. By measuring the total distance and knowing the time, they can calculate the average speed of the cart using the formula v = d / t, where v is the average speed, d is the distance traveled, and t is the time taken.

Therefore, the two quantities that the student can measure to determine the inertial mass of the cart are the acceleration of the cart and the total distance traveled by the cart.

Answer:

Only there will be a change in density of sun.

Explanation:

As your question says only the radius of sun is decreased and there is no change in the mass. So it means that the center of gravity will be the same and as a result the gravitational force remains the same. Only the density of sun changes as it shrinks.

Answer: Nothing significant.

Explanation: The energy flux emited by the sun will remain the same even if the sun's radius reduces drastically.

The energy from the sun reaching the Earth is given by the Stefan-Boltzmann equation.

Energy flux = Boltzmann's constant * T⁴

Energy flux = {{5.67*EXP(-8) watt per meter² per K⁴}*{5800K}⁴} = 63*EXP(6) Watt per meter²

Where EXP means 10^, and T= sun blackbody temperature 5800K.

It is good to know that the energy flux from the sun reaching the Earth does not depend on radius ( either it increases or decreases). The energy it supplies to earth remain the same.

Final answer:

Two vectors with different magnitudes can add up to zero only if they are antiparallel. For three or more vectors of different magnitudes, they can sum to zero if they form a closed shape. The maximum distance achieved by adding two vectors is the sum of their lengths if they are in the same direction.

Explanation:

When dealing with vectors, it is possible for two vectors with different magnitudes to add up to zero if they are equal in magnitude but opposite in direction, making them antiparallel. This is due to the definition of vector addition, which considers both magnitude and direction.

For example, if you take a step of 5 units to the north (vector A) and then a step of 5 units to the south (vector B), you will end up back at your starting point as these two vectors cancel each other out. This can only happen if the two vectors are directly opposite to each other (antiparallel).

However, in the more general case with three or more vectors, they can add to zero even if they have different magnitudes, as long as they form a closed shape like a triangle or a polygon when placed tip-to-tail. The result of adding multiple vectors together in such a manner would be zero, bringing you back to your starting point.

Moreover, the maximum distance you can end up from the starting point when adding two vectors A and B is indeed the sum of their lengths, but only when the vectors are aligned and pointing in the same direction. When they point in opposite directions, the maximum distance will be the difference in their lengths.

The percent decrease in the number of errors committed by the baseball player is 33.33%, calculated by finding the difference in errors between the two years and dividing by the number of errors in the first year.

To calculate the percent decrease in the number of errors committed by the baseball player, we need to first find the difference in the number of errors between the two years and then divide that by the number of errors made in the first year. Finally, we'll multiply the result by 100 to get the percentage.

Answer:

at the Equator

Explanation:

The four seasons are determined by four main positions in the Earth's orbit in its turn around the Sun (ecliptic plane), which are called solstices and equinoxes: winter solstice (Capricorn point, December 22), spring equinox (Aries point, around March 21-22), summer solstice (Cancer point, June 21) and autumn equinox (Libra point, around September 22-23).

In the equinoxes, the axis of rotation of the Earth is perpendicular to the sun's rays, which fall vertically over the equator. In solstices, the axis is inclined 23.5º, so that the sun's rays fall vertically on the Tropic of Cancer (summer in the northern hemisphere) or Capricorn (summer in the southern hemisphere).

When falling vertically on Ecuador, it generates a greater impact on the surface of the Tierre reaching a greater amount of energy and therefore UV rays.

Answer:

In no case does the amplitude appear, so we would not have to change the period of the system when we change to the amplitude

Explanation:

In the harmonic movement when the amplitude of oscillation increases, body speed also increases, so the frequency remains constant.

When we solve the different case of harmonic movement

Simple pendulum 2pi f = Ra l / g

Spring mass 2pi f = RA k / m

2pi torsion pendulum f = RA I / k

In no case does the amplitude appear, so we would not have to change the period of the system when we change to the amplitude

Answer:

The frequency does not depend on the amplitude for any (ideal) mechanical or electromagnetic waves.

In electromagnetism we have that the relation is:

Velocity = wavelenght*frequency.

So the amplitude of the wave does not have any effect here.

For a mechanical system like an harmonic oscillator (that can be used to describe almost any oscillating system), we have that the frequency is:  

f = (1/2*pi)*√(k/m)

Where m is the mass and k is the constant of the spring, again, you can see that the frequency only depends on the physical properties of the system, and no in how much you displace it from the equilibrium position.

This happens because as more you displace the mass from the equilibrium position, more will be the force acting on the mass, so while the "path" that the mass has to travel is bigger, the mas moves faster, so the frequency remains unaffected.

Answer:

2.50 m/s

Explanation:

This question can be solved using momentum conservation equation

combined mass of crow and feeder = 450+670=1120 gm

let the recoil speed of feeder be v m/s

Then applying momentum conservation we get;

1120×1.5 = 670×v

v= 2.50 m/s

the speed at which the feeder initially recoils backwards = 2.50 m/s

Final answer:

By applying the conservation of momentum principle, the feeder initially recoils at a speed of approximately 1.007 meters per second when a 450-gram crow pushes off of it with a takeoff speed of 1.5 m/s.

Explanation:

The question you've asked is rooted in the principle of conservation of momentum in physics. When the crow pushes off from the feeder, both the crow and the feeder will have momenta that are equal in magnitude and opposite in direction, assuming no external forces act on the system. The situation described can be solved using the formula for conservation of linear momentum, which states that the total momentum of a closed system remains constant if no external forces are acting on it.

To find the speed at which the feeder recoils, we use the fact that the initial momentum of the system (before the crow pushed off) was zero since the feeder was at rest. Consequently, the momentum of the crow after pushing off and the momentum of the feeder must cancel each other out:

Mass of crow imes Velocity of crow = Mass of feeder imes Velocity of feeder

(450 g) imes (1.5 m/s) = (670 g) imes Velocity of feeder

We now need to solve the Velocity of the feeder:

Velocity of feeder = (450 g imes 1.5 m/s) / (670 g)

Velocity of feeder = (675 g imes m/s) / (670 g)

Velocity of feeder \ 1.007 m/s

Note that we converted the masses to kilograms in the calculation (which isn't shown above) because the unit of mass in the formula for momentum (p = mv) should be in kilograms to match with the unit for velocity in meters per second (m/s). The feeder recoils at a speed of approximately 1.007 meters per second.

Answer:

The average force between the ball and bat during contact is 3006.72  N.

Explanation:

Given that,

Mass of the baseball, m = 0.145 kg

Initial speed of the ball, u = 27 m/s

Time of contact between bat and ball is 2.5 ms, [tex]t=2.5\times 10^{-3}\ s[/tex]

After striking the bat, it pops straight up to a height of 31.5 m. The final velocity of the ball is given by using third equation of motion as :

[tex]v^2-u^2=2as[/tex]

a = -g

And initially, u = 0

[tex]v=\sqrt{2gs}[/tex]

[tex]v=\sqrt{2\times 9.8\times 31.5}[/tex]

v = -24.84 m/s (as it pops straight up)

Let F is the average force between the ball and bat during contact. It is given by :

[tex]F=\dfrac{m(v-u)}{t}[/tex]

[tex]F=\dfrac{0.145\times (24.84 -(-27))}{2.5\times 10^{-3}}[/tex]

F = 3006.72  N

So, the average force between the ball and bat during contact is 3006.72  N. Hence, this is the required solution.

c.A and B must point in opposite direction.

d. A and B must point in the same direction.

e.A and B must be at right angles to each other."

answer:

d. A and B must point in the same direction.

Explanation:

a.false:From vector analysis, all forms of vector with the same unit can be added, and we add vector component by component. hence this defile option (a).

b. false: in addition of vectors, length is not a criteria to consider before carrying out the operation, hence vectors of different lengths can be  added

c. false: this is against the claim as vectors in opposite direction can give rise to a new vector of negative value.

d. true: this is true as vector in the same direction add up to give rise to another vector.

e.false: this is not a true assumption

The relationship A + B = C only holds for vectors A and B that are collinear. Generally, the magnitude of the resultant vector C is derived using the triangle rule of vector addition, and is not a simple sum of the magnitudes of vectors A and B.

The relationship between the magnitudes of vectors A, B, and C is not always expressed as A + B = C. This can only be true in the special case where the vectors A and B are collinear (aligned along the same line and direction).

In general, according to the triangle rule of vectors addition, if we add two vectors A and B (not necessary to be in the same direction), the resultant vector C can be represented by the diagonal of a parallelogram which is constructed using A and B as two adjacent sides. Meaning, |C|= √ (A² + B² + 2ABcosθ), where θ is the angle between A and B.

Answer:

The affirmation is only true if the truck is traveling at 50 mi/h.

Explanation:

Hi there!

Let´s use the equation of average velocity (AV) to solve this problem:

AV = Δx / t

Where:

Δx = traveled distance.

t = time.

For the car, its average velocity (vc) will be:

vc = 120 miles / t

For the truck:

vtr = 100 miles / t

If we solve both equations for t and then equalize them (since the time is the same for both vehicles):

vc = 120 miles / t

t = 120 mi / vc

vtr = 100 miles / t

t = 100 mi / vtr

120 mi / vc = 100 mi / vtr

multiply both sides by vc and divide by 100:

120 mi / 100 mi = vc / vtr

1.2 = vc / vtr

1.2 · vtr = vc

The car travels 1.2 times faster than the truck.

Let´s see at which velocity of the truck, the car is traveling 10 mi/h faster. In this case, vc = 10 mi/h + vtr:

1.2 · vtr = 10 mi/h + vtr

1.2 vtr - vtr = 10 mi/h

0.2 vtr = 10 mi/h

vtr = 10 mi/h / 0.2

vtr = 50 mi/h

The affirmation is only true if the truck is traveling at 50 mi/h.

Answer:

The answer is h/4

Explanation:

When Peter collides with Fred, the collision is inelastic & they both proceed with a velocity of V/2.

let m represent the masses for Peter & Fred

v represent the initial velocity of Peter

V represent final velocity of both of them

mv + 3m × 0 = (m+m)V

V = v/2

Using the expression; H = v² / 2g .............Eqn 1

Upon substitution of V/2 into Eqn 1 above,

H = (V/2)² / 2g

H = (V²/4) ÷ 2g

Therefore height will be h/4

Final answer:

In a semi-circular halfpipe scenario, Peter starting from rest at a height h and colliding with Fred will result in an inelastic collision, where they would not reach the initial height h due to the combined mass and shared kinetic energy post-collision.

Explanation:

The question you are asking regards a physical scenario involving conservation of energy and momentum in a skateboarding situation. When Peter, starting from rest at a height h, collides with Fred, who is at the bottom, the collision will exchange energy and momentum between the two. Assuming they have the same mass and the collision is perfectly inelastic (they stick together), they will move together with a combined mass of 2m (where m is the individual mass of Peter or Fred) and reach a new height that is less than h.

Based on the conservation of energy, because there are no external forces doing work (ignoring friction and air resistance), the potential energy at the initial height h will be equal to the kinetic energy at the bottom of the halfpipe. In an inelastic collision where the two objects stick together, they move with a common velocity after the collision. Since the kinetic energy after the collision must be shared by both masses, the combined system must have less kinetic energy per unit mass than Peter did alone before the collision, therefore, they won't reach the original height h.

Answer:increased

Explanation:

It is given that elevator speed is increasing while moving upward i.e.its acceleration is increasing .

This causes the apparent to be increased if measured using weighing machine.

considering upward direction to be positive

N-mg=ma

N=m(g+a)

where N=Normal reaction=Apparent weight

a=acceleration of Elevator

thus you feel as if your weight is increased.

When an elevator accelerates upwards, your weight feels heavier due to the additional force pushing you into the floor.

Acceleration is the rate of change of an object's velocity with respect to time. It is a vector quantity, measured in meters per second squared in the International System of Units (SI). Acceleration can be positive (speeding up), negative (slowing down), or zero (constant velocity), and it plays a crucial role in describing the dynamics of motion.

When an elevator starts moving upwards with increasing speed, your weight will feel heavier compared to when the elevator is at rest. This increase in weight is due to the upward acceleration experienced by both you and the elevator. The force of gravity acting on your body remains the same, but now there is an additional force pushing you against the floor of the elevator, resulting in the feeling of increased weight.

Topographic survey helps to assess a land for a new construction or the addition of new development.it is invaluable for showing what the the land looks like and how it would impact or affect construction, and this assessment is relevant for all kind of projects such as road improvements,new housing ,complex construction, major highway construction ,grading ,bridge erection,septic system installation,and drainage projects,e.t.c.

 Topographic survey is also very important in for identifying areas that construction may not be feasible or where grading will be required in order to make it feasible. This survey provides architects and builders with required information so as to determine how the land will have be shaped and molded to provide a suitable base for the planned construction.

On completion of an initial project topographic survey can be used as basis for a other subsequent plans and designs.Topographic survey can be used  for environmental reclamation projects. This survey and the information they provide on elevation and terrain features can help in the accurate and successful reconstruction of a given landscape.

Considering the  question that requires filling the blank space

 We see that Geological has to do with beneath the land hence its not suitable

Hence

The first blank should be filled with TOPOGRAPHIC

The second blank should be CONSTRUCTION

The third blank should be filled with  SURVEY

Note: A construction survey is one that gives the location and sites for construction activities,

The Fourth  blank should be DELINEATION

Delineation can be defined as the act of drawing sketching or tracing an outline.
