Why does refraction occur?
irina1246 [14]

Answer:

The answer is C.

Explanation:

Let's take a glass of water as an example. Now, shine a flashlight on it. See it bend the light into a rainbow? That is a example of refraction. When the light enters the water, the water actually slows down and changes its direction, causing the light to come out the other side in a different way. Since water is very dense, it can bend the water and make it different.

The power needed to accelerate a projectile from rest to its launch speed v in a time t is 42.0 W. How much power is needed to a
ExtremeBDS [4]

Answer:168 W

Explanation:

Given

Power needed P=42 W

initial Launch velocity is v

Energy of projectile when it is launched E=\frac{1}{2}mv^2

Power=\frac{Energy}{time}

Power=\frac{E}{t}

42=\frac{\frac{1}{2}mv^2}{t}--------1

Power when it is launched with 2 v

E_2=\frac{1}{2}m(2v)^2=\frac{4}{2}mv^2

P=\frac{2mv^2}{t}---------2

Divide 1 & 2 we get

\frac{42}{P}=\frac{1}{2\times 2}

P=42\times 4=168 W
