In a pool game, the cue ball, which has an initial speed of 3.0 m/s, make an elastic collision with the eight ball, which is ini
zhenek [66]

Explanation:

Given

initial speed(u)=3 m/s

mass of each ball is m

Let the cue ball is moving in x direction initially

In elastic collision Energy and momentum is conserved

Let u be the initial velocity and v_1 , v_2 be the final velocity of 8 ball and cue ball respectively

\frac{mu^2}{2}+0=\frac{mv^2_1}{2}+\frac{mv^2_2}{2}

The angle after which cue ball is deflected is given by

\theta _1=90-40=50^{\circ}

Conserving momentum in x direction

mu=mv_1cos40+mv_2cos50

3=v_1cos40+v_2cos50

Along Y axis

0+0=v_1sin40-v_2sin50

v_1sin40=v_2sin50

substitute the value of v_1

we get v_2=1.912 m/s

v_1=2.27 m/s

The bear is white in color because it is a polar bear.

<h3>What are the color of bears?</h3>

Bears are very large carnivorous animals found around the cold regions of the Arctic or North Pole.

The color of bears, may be brown, black or white depending on how far North the bears are found.

Bears found close to the Arctic or North pole are white polar bears.

Based on the description of the house, every side of the home faces South meaning that the individual lives in the North pole.

Therefore, the color of the bear will be white.

in conclusion, polar bears are white in color.

How does a prism split white light into a rainbow?
bearhunter [10]

Answer:

Explanation:

DECOMPOSITION OF LIGHT:

Descartes explained the formation of the rainbow and years later Newton studied the light and managed to break it down into the colors of its spectrum through a prism year 1666.

Newton knew very little about the nature of light, did not know that it was a wave and even less that it was an electromagnetic wave. He believed that it was formed by corpuscles, but he managed to break it down into its spectral colors. Today we know that light is both particle and wave.

Humans (and some animals) appreciate a wide range of colors that are usually due to the mixture of radiation (lights) of different wavelengths. The color of light with a single wavelength or a narrow band of them is known as pure color.

When the light passes through a glass prism, the different wavelengths that make up the light beam travel inside it at different speeds and curl differently when entering and leaving (double refraction when changing media) giving as result a beam diverted from the initial direction and with its separate components. Thus arises the solar spectrum.

Each of the different rays of light crosses the glass with different velocity and the average speed of light within the prism is less than in a vacuum. Light is a wave with an oscillating electric field that interferes with the charged particles in matter.

The visible radiations are between the following wavelengths: from 350 nm (nanometers) for violet to 750 nm for red.
