Answer:

Explanation:

Momentum depends on mass and velocity

Second part

Momentum = m * v

If you triple the velocity, you are going to have to triple the momentum

3*momentum = m * 3v

momentum started at 50. If you triple it, you get 3 * 50 = 150 kg m/s

Explanation:

When the string moves, it creates a very small change in the distance to the next point, this generates a restoring force that tends to push the string back, this small disturbance propagates along the string and is what creates the pulse.

This is similar to what happens when a spring is stretched and a restoring force is generated shaved by the law of shortening.

Why did one-half of the Moon's surface remain
choli [55]

Answer:

The moon's revolution around its axis and the moon's revolution around the Earth take the same time, approximately 27 days. That causes one side of the Moon to always face the Earth while the other side always faces away from the Earth. That is why it took probes to go into space to photograph the side that is never visible from Earth for people to be able to see it.

A point charge of magnitude q is at the center of a cube with sides of length L.a) What is the electric flux through each of the
agasfer [191]
<h2>The flux through each face is q/6ε₀ .</h2>

Explanation:

The charge q is placed at the center of the cube of side L

According to Gauss's law the flux through any closed surface is q/ε₀

here q is the charge enclosed .

In this case cube has the six faces . The flux through each face = q/6ε₀

In the second case The cube has the face with length L₁

The flux through each face = q/6ε₀

Thus flux through the cube does not depend upon the size of the cube .
