Answer 2

The mechanical advantage and the efficiency of the ramp are respectively;

330 N and 90%

Mechanical advantage and Efficiency

I have drawn an image of the force diagram on the crate and attached it.

Applying Newton's second law to the force diagram attached, we have;

F_fric + F + N + mg = 0

Projecting forces gives us;

In the x-direction;

F = F_fric + mg*sin α

In the y-direction;

N - mg*cos α = 0

Also;

F_fric = μmg*cos α

Thus;

F = (μmg*cos α) + (mg*sin α)

Mechanical advantage is;

ΔF = mg - F

ΔF = mg - mg((μ cos α) + (sin α))

Since the ramp is 3 m high and 5 m long, then by trigonometric ratios;

(sin α) = 3/5

cos α = 4/5

But we are given that F is 650 N.

Thus;

ΔF = (100 × 9.8) - 650

ΔF = 330 N

Efficiency of the ramp is;

η = (mgh/Fl) × 100%

η = (100 × 9.8 × 3/(650 × 5)) × 100%

η ≈ 90%

A 1,155 kg truck has a velocity of 18 m/s. What is the momentum of the truck?
Round your answer to the whole number.

Answers

The momentum of truck is 20790 kg m/s

Solution:

Given that we have to find the momentum of truck

From given, 1155 kg truck has a velocity of 18 m/s

Therefore,

Mass = 1155 kg

Velocity = 18 m/s

The momentum is given by formula:

[tex]p = m \times v[/tex]

Where, m is mass in kg and v is velocity in m/s

Substituting the values we get,

[tex]p = 1155 \times 18\\\\p = 20790[/tex]

A shallow slope on a phase-change graph indicates _____.

A. a little temperature increase for a lot of heat

B. a phase change

C. a large change in kinetic energy of the molecules

D. a high latent heat

Answers

A shallow slope on a phase-change graph indicates - A. a little temperature increase for a lot of heat.

To understand this, let's break down the concepts involved:

Latent Heat: When a substance undergoes a phase change (like melting or boiling), it absorbs or releases heat without changing temperature. This heat is known as latent heat.

Phase Changes: During a phase change, such as ice melting into water, the temperature of the ice remains at 0°C until it has completely melted. Only after the phase change is complete does the temperature of the water begin to increase.

Shallow Slope on Graph: In a graphical representation, the shallow slope during a phase change signifies that while a large amount of heat is added, the temperature remains constant until the phase change is completed. This reinforces the idea that energy is being used to break molecular bonds rather than increasing kinetic energy.

it takes 0.6 seconds for it to reach the floor,
a. What is the vertical component of the ball's velocity just
before it hits the floor? (Use g = 10 m/s2.)
b. What is the horizontal component of the ball's velocity
just before it hits the floor?

Answers

The vertical component of the ball's velocity just  before it hits the floor is 6.0m/sThe horizontal component of the ball's velocity  just before it hits the floor is 5m/s

a) To get the vertical component of the ball's velocity just  before it hits the floor, we will use the equation of motion expressed as:

[tex]v_y = u + gt[/tex]

where:

u is the initial velocity

g is the acceleration due to gravity

t is the time taken

Given the following:

u = 0m/sg = 10m/s²t = 0.6secs

Substitute into the formula as shown:

[tex]v_y=0+10(0.6)\\v_y=6.0m/s[/tex]

Hence the vertical component of the ball's velocity just  before it hits the floor is 6.0m/s

b) Since the ball rolls off a table with a horizontal velocity of 5 m/s, hence  the horizontal component of the ball's velocity  just before it hits the floor

is 5m/s

Final answer:

The vertical component of the ball's velocity just before it hits the floor is 6 m/s and the horizontal component of the ball's velocity just before it hits the floor is 5 m/s.

Explanation:

a. The vertical component of the ball's velocity just before it hits the floor can be calculated using the formula v = gt, where g is the acceleration due to gravity and t is the time. Therefore, v = 10 m/s2 x 0.6 s = 6 m/s.

b. The horizontal component of the ball's velocity just before it hits the floor remains the same as the original horizontal velocity, which is 5 m/s. This is because in the absence of air resistance, there are no horizontal forces acting on the ball after it leaves the table, so its horizontal velocity remains constant.

A rope vibrates every 0.5 s. What is the frequency of the waves? 5 Hz 2 Hz 0.5 Hz 1 Hz

Answers

The answer is 2Hz

Using the formula f= 1/T we can plug in .5 for T and solve for frequency.

The frequency of the waves generated by a rope that vibrates every 0.5 seconds is 2 Hz, as frequency is the inverse of the period. Hence, the correct answer is B.

The frequency of a wave is defined as the number of cycles per second, and it is the inverse of the period (the time for one complete cycle). So, if a rope vibrates every 0.5 seconds, that means the period (T) is 0.5 seconds. To find the frequency (f), we use the formula f = 1/T. Therefore, the frequency of the waves is f = 1/0.5 s = 2 Hz.

What is the cost of using an electric iron rated 340v,1000w for 24hrs. If electric energy costs 3000tsh per unit?(1unit=1kwh)

Answers

Total cost of electric iron used for 24 hrs is 72000 tsh.

Explanation:

Given

Voltage, V = 340 V

Power, P = 1000 W  = 1 kW

Time, T = 24 hrs

Cost per unit = 3000 tsh /unit

Total cost, T = ?

We know,

The cost is calculated in kWh

Therefore,

Total Power consumed = 1 kW X 24 hrs

Total Power consumed = 24 kWh

Total cost = total power X cost per unit

Total cost = 24 kWh X 3000 tsh/unit

Total cost = 72000 tsh

Therefore, total cost of electric iron used for 24 hrs is 72000 tsh.

For a positive point charge, the lines radiate ………. . While, for a negative point charge, the lines converge …………. .

Answers

Answer:

For a positive point charge, the lines radiate outward. While, for a negative point charge, the lines converge inward.

Explanation:

The electric field produced by a single point charge has a radial shape and follows an inverse square law. The magnitude is given by

[tex]E=k\frac{q}{r^2}[/tex]

where

k is the Coulomb's constant

q is the magnitude of the charge

r is the distance from the charge

The direction of the field depends on the sign of the charge. In particular, we have:

For a positive charge, the direction of the field is out of the chargeFOr a negative charge, the direction of the field is towards the charge

This is due to the fact that the direction of the field shows the direction of the force that a positive test charge would experience in this field. Therefore, since a positive test charge would feel a repulsive force in the field produced by a positive charge, then the direction of the field is outward; on the other hand, a positive test charge would feel an attractive force in the field produced by a positive charge, therefore the direction of the field is inward.

Explanation:

As we know that kinetic energy is given as

[tex]K = \frac{1}{2}mv^2[/tex]

here we know that

m = 3 kg

v = 4 m/s

so we will have

[tex]k = \frac{1}{2}(3)(4^2)[/tex]

[tex]k = 24 J[/tex]

so kinetic energy of the object is 24 J

The kinetic energy of the object is 24 J.

That is,

[tex]KE = \dfrac{1}{2}mv^{2}[/tex]

Here, KE is the kinetic energy of object.

Solving as,

[tex]KE = \dfrac{1}{2} \times m \times v^{2}\\\\KE = \dfrac{1}{2} \times 3 \times 4^{2}\\\\KE = 24 \;\rm J[/tex]

6) 100 ml of water is initially at 20°C. 30,000 J of heat is added to the water. What is temperature change for the water?

Answers

Δt = 71.67 °C

The temperature change of water is equal to 71.67 °C

Explanation:

Given:

Amount of transferred energy = 30,000 K J

Mass of water = 100 ml

Initial temperature = 20°C

To find the change in temperature of water.

Formula for Heat capacity is given by

Q = m×c×Δt ........................................(1)

where:

Q = Heat capacity of the substance (in J)

m=mass of the substance being heated in grams(g)

c = the specific heat of the substance in J/(g.°C)

Δt = Change in temperature (in °C)

Δt = (Final temperature - Initial temperature) = T(f) - T(i)

Q = 30,000 J

Mass of water = m = 100 ml

1 ml = 1 g ................................................(2)

Therefore m = 100 ml = 100 g

Specific heat of water is c = 4.186 J /g.

Δt = ?

Substituting these in equation (1), we get

Q = m×c×Δt

Rearranging the terms for Δt,

Δt = [tex]\frac{Q}{m\times c}[/tex]

Δt = [tex]\frac{30,000}{100\times 4.186} = \frac{30,000}{418.6}= 71.67\°C[/tex]

Δt = 71.67 °C

Why are airbags, helmets, and other safety devices important? Physics

Answers

Answer:to prevent serious damage when an accident occur

Explanation:to prevent serious damage when accident occur

Airbags and other safety devices are important as they use the physics concept of impulse to reduce the force on an individual by increasing the impact duration during collisions, thereby reducing the likelihood of injuries or fatalities.

Airbags, helmets, and other safety devices are crucial because they employ the concept of impulse from physics, which helps in reducing the force felt by individuals during collisions. Impulse is defined as the net force multiplied by the time duration over which it acts ([tex]F_{net}[/tex] Δt). When a vehicle is involved in an accident, safety devices such as airbags extend the time over which a person's momentum is brought to a stop. Consequently, the force exerted on their body is significantly reduced, minimizing the risk of severe injuries or fatalities. The concept is that by increasing the time Δt, while the momentum change Δp remains constant, the net force [tex]F_{net}[/tex] is decreased, which illustrates an inverse relationship between force and time during impact. This principle not only applies to airbags, which allow for a more gradual deceleration and less forceful impact but to other vehicle safety aspects, such as crumple zones that extend the collision time, hence reducing the force and potential injury.

Two trains are traveling side-by-side along parallel, straight tracks at the same speed. In a time t, train A doubles its speed. In the same time train B increases its speed by a factor of 5.42. By what factor is the distance traveled by train B in time t greater than the distance traveled by train A in the same time t?

Answers

Answer:

yes

Explanation:

Final answer:

The distance traveled by train B in time t is 5.42 times greater than the distance traveled by train A in the same time t.

Explanation:

The distance traveled by train B in time t is greater than the distance traveled by train A in the same time t by a factor of 5.42.

To understand this, let's assume the initial speed of both trains is v. After time t, train A doubles its speed, so its new speed is 2v. On the other hand, train B increases its speed by a factor of 5.42, so its new speed is 5.42v.

Since the distance traveled by a train is directly proportional to its speed, the distance traveled by train B will be 5.42 times greater than the distance traveled by train A in time t.

Answer:

Force = mass x acceleration i.e F = ma

Explanation:

The force equation is in accordance with Newton's second law of motion, the law states that the acceleration of an object depends on two variables which are

i)  The force acting upon the object.

ii) The mass of the object.

The acceleration of an object is directly proportional to the force acting on the object, and inversely proportional to the mass of the object.

This means that if the force acting on the object increases, the acceleration of the object will also increase and if the mass of the object increases, the acceleration of the object will decrease.

a ∝ F  ------ eqn 1

a ∝ [tex]\frac{1}{m}[/tex] ------ eqn 2

where a = acceleration

F = Force

m = mass

Applied force is the interaction of an object which can be described as an active agent with another object which causes the second object to either accelerate, experience a change in velocity, a change in direction or bring to a halt.

Mass is the amount of matter or substance that makes up an object.

Acceleration is a measure of the change in velocity of an object with respect to time.

combining eqn 1 and eqn 2

[tex]a = \frac{F}{m}[/tex]

i.e

F = ma  ------ eqn 3

eqn 3 is the force equation

A force equation depicts the relationship between force, mass, and acceleration. An object of mass m will accelerate given that force F is applied to it.

Answers

The mechanical energy isn't conserved. Some energy is lost to friction.

Option A.

Explanation:

The mechanical energy is defined as the energy of a body which it achieves by virtue of its position and velocity. The mechanical energy are of two types - potential energy and kinetic energy. The potential energy is the energy of the body which it achieves by means of its relative position and is directly proportional to the height of the body from its relative plane. Whereas the kinetic energy of the body is achieved by virtue of its velocity and is directly proportional to the square of velocity of the body.

As the mountaineer is skiing down the slope of a mountain, the potential energy of the person is gradually changing into his kinetic energy. Had it been in an ideal situation, the potential energy lost would have been just equal to the kinetic energy gained by the person. But there's friction which opposes the speed of the body and reduces the velocity. Thus the kinetic energy will be lost to some extent and the energy won't be conserved.

the correct answer is B) The mechanical energy isn't conserved. Some energy is lost to friction.
