Which part of the electromagnetic spectrum is nearest to X-rays?

Answer:

The weight of the object

Explanation:

The downward pull on an object due to gravity is equal to the weight of the object, which is given by

[tex]W=mg[/tex]

where

m is the mass of the object

g is the acceleration due to gravity (on Earth surface, g=9.8 m/s^2)

The weight is a force so it is measured in Newtons (N).

Note that while the mass of an object (m) depends only on the properties of the object, so it does not depend on the location, the weight of the object depends on the value of g, which can change depending on the location (for instance, on the Moon g is 1/6 of the value on Earth), so the weight is not constant.

Using more wire loops

Answer:

using more wire loops.

Explanation:

When there is a change in magnetic flux linked with a coil changes, an emf is induced in the coil. This phenomenon is called electromagnetic induction.

the amount of induced emf developed is

[tex]e = \frac{d\phi }{dt}[/tex]

If there are N number of turns in the coil, then induced emf is given by

[tex]e = N\frac{d\phi }{dt}[/tex]

Induced current is given by

i [tex]i = \frac{e }{R}[/tex]

So, as number of turns increases, the current produced is also increases.

Answer:

45 V

Explanation:

The voltage across the resistor can be found by using Ohm's law:

[tex]V=RI[/tex]

where

R is the resistance

I is the current

In this circuit,

[tex]R=3 \Omega[/tex]

[tex]I=15 A[/tex]

Therefore, the voltage across the resistor is

[tex]V=(3\Omega )(15 A)=45 V[/tex]

Voltage = (current) x (resistance)   <== memorize this formula

Voltage = (15 Amperes) x (3 ohms)

Voltage = 45 volts

Answer:

2.7 m/s²

Explanation:

Average acceleration is change in velocity over change in time.  Assuming the acceleration is constant, we can say it is equal to the average:

a = Δv / Δt

a = (6.0 m/s - 0 m/s) / 2.2 s

a ≈ 2.7 m/s²

Answer:

Waves interact in a very unique way with the water. Waves often line up parallel to the water surface due to refraction of waves. The parallels depends on the angle from where the waves are hitting the water.

If the waves are coming from deep down the ocean at an angle to the surface, they will most probably refract towards the shallower part of the water and curve around which makes them even more parallel to the surface of water.

In an ionic compound's chemical formula, the positive ion (or cation) is written first, followed by the negative ion (or anion).

Ionic compounds are formed when positively charged ions (cations) and negatively charged ions (anions) come together due to electrostatic attraction. In the chemical formula of an ionic compound, it's customary to write the cation (positive ion) first and the anion (negative ion) second.

For example, let's take the compound "Sodium Chloride" (table salt). Sodium (Na) is the cation, which has a positive charge, and chloride (Cl) is the anion, which has a negative charge. In the chemical formula for sodium chloride, the positive ion (Na) is written first, followed by the negative ion (Cl). The formula is NaCl.

So, when presented with options A, B, C, and D, the correct choice is A, as it aligns with the convention of writing the name of the positive ion first in the chemical formula of an ionic compound.

Final answer:

The velocity at which the softball must be moving to equal the momentum of the baseball is 12.30 m/s.

Explanation:

To find the velocity at which the 0.53 kg softball must be moving to equal the momentum of the 0.31 kg baseball, we can use the equation for momentum:

Momentum = mass × velocity

First, let's find the momentum of the baseball:

Momentum of baseball = 0.31 kg × 21 m/s = 6.51 kg·m/s

Now, we can set the momentum of the softball equal to the momentum of the baseball and solve for its velocity:

Momentum of softball = 6.51 kg·m/s

0.53 kg × velocity = 6.51 kg·m/s

velocity = 6.51 kg·m/s / 0.53 kg = 12.30 m/s

Therefore, the softball must be moving at a velocity of 12.30 m/s to equal the momentum of the baseball.

In the series resistor circuit, the electric current flows only one path. In the parallel resistor circuit, the current divides and circulates through several paths. These resistances are joined by their two extremes.

The equivalent resistance of a resistor circuit in parallel is equal to the reciprocal of the sum of the inverse of the individual resistors.

For the general case with "n" resistances in parallel the formula is:

[tex]\frac{1}{R_{n} }=\frac{1}{R_{1}}+ \frac{1}{R_{2}} +\frac{1}{R_{3}}+....\frac{1}{R_{n} }[/tex]

Answer:

Wouldn't it be the muscles in your arms or legs since they have to push the most while they have gravity acting upon them?

Explanation:

Answer:

1.3 m/s², 210 m

Explanation:

Average acceleration is change in velocity over change in time.

First, convert to SI units.

30. mph ≈ 13.4 m/s

60. mph ≈ 26.8 m/s

a = Δv / Δt

a = (26.8 m/s - 13.4 m/s) / 10.5 s

a = 1.28 m/s²

Rounded to 2 sig-figs, your acceleration is 1.3 m/s².

The distance traveled is:

x = x₀ + ½ (v + v₀)t

x = (0 m) + ½ (26.8 m/s + 13.4 m/s) (10.5 s)

x = 211 m

Rounded to 2 sig-figs, you and your date traveled 210 m.

Final answer:

The acceleration of the car was approximately 1.27728 m/s², and the distance traveled during the acceleration was approximately 211.69242 meters.

Explanation:

To calculate the acceleration, we can use the formula:

a = (Vf - Vi) / t

Where Vf is the final velocity, Vi is the initial velocity, and t is the time. Plugging in the values given, we get:

a = (60 mi/hr - 30 mi/hr) / 10.5s

To make the units consistent, we should convert the velocities from miles per hour to meters per second. Since 1 mi/hr is approximately equal to 0.44704 m/s, after conversion we get:

a = (26.8224 m/s - 13.4112 m/s) / 10.5s = 1.27728 m/s²

To find the distance traveled during acceleration, we use the formula:

d = Vi*t + 0.5*a*t²

Substituting the known values, we find:

d = 13.4112 m/s * 10.5s + 0.5 * 1.27728 m/s² * (10.5s)² = 140.8176 m + 70.87482 m

The total distance traveled by your date during the acceleration is approximately 211.69242 meters.

Answer:

-272 m/s, 8.03 m/s²

Explanation:

Let's call position 0 the point where the two spacecrafts meet.  Let's say spacecraft #1 starts x units to the left of 0 and spacecraft #2 starts 13500-x units right of 0.

For spacecraft #1:

v = 0 m/s

v₀ = 525 m/s

a = -15.5 m/s²

x = 0 m

x₀ = -x

The distance that spacecraft #1 travels is:

v² = v₀² + 2a(x - x₀)

(0 m/s)² = (525 m/s)² + 2(-15.5 m/s²)(0 m − -x)

0 = 275625 − 31x

x ≈ 8891 m

The time it takes to reach 0 velocity is:

v = at + v₀

0 m/s = (-15.5 m/s²) t + 525 m/s

t ≈ 33.87 s

For spacecraft #2:

v = 0 m/s

x = 0 m

x₀ = 13500-x ≈ 4609 m

t = 33.87 s

Using the same equations:

v² = v₀² + 2a(x - x₀)

(0 m/s)² = v₀² + 2a(0 m − 4609 m)

0 = v₀² − 9218a

v = at + v₀

0 m/s = a(33.87 s) + v₀

0 = 33.87a + v₀

Now we have two equations and two variables.  We can solve the system of equations.

First, let's solve for a and substitute:

0 = 33.87a + v₀

a = -v₀ / 33.87

0 = v₀² − 9218 (-v₀ / 33.87)

0 = v₀² + 272 v₀

0 = v₀ (v₀ + 272)

v₀ = -272 m/s

Now we can find the acceleration:

a = -(-272) / 33.87

a = 8.03 m/s²

By utilizing the equations of motion, you can calculate the exact time it will take for the first spacecraft to come to rest and then apply this to find the acceleration needed for spacecraft#2 to stop in the same time. Additionally, using these equations, we can figure out the initial velocity of spacecraft#2.

To find the initial velocity and constant acceleration for spacecraft #2, we can use the basic principles of physics. The equations of motion are our primary tool in this context, which state that the final velocity of an object is equal to its initial velocity plus acceleration multiplied by time, and the displacement of an object is equal to its initial velocity multiplied by time plus one-half of its acceleration multiplied by time squared.

If both spacecraft are to meet at the same time and come to rest (which means final velocity equals zero), then spacecraft#1 and #2 should cover half the distance each, i.e., 6750 m. Thus, we can use the first equation of motion for spacecraft #1 to find the time it takes for it to come to rest. If we calculate the time, we can use that to determine the constant acceleration required for spacecraft #2 to come to rest in the same time using the second equation of motion. Similarly, the initial velocity of spacecraft #2 can be obtained.
