When light goes through a material but changes direction, the process is called..

Physics
1 answer:
Luden [163]3 years ago
6 0

Answer:

<h2><em>This change of direction is called refraction. When light enters a more dense substance (higher refractive index), it 'bends' more towards the normal line. The amount of bending depends on two things: Change in speed – if a substance causes the light to speed up or slow down more, it will refract (bend) more.</em></h2><h2><em>Hop</em><em>e</em><em> it</em><em> helps</em><em>.</em><em>.</em></h2>

At what speed must a 0.6 kg stone be thrown in order that it has a relativistic mass of 0.76 kg? (c = 3.00 x 10^8 m/s) A) 0.6976
soldier1979 [14.2K]

Answer:

The speed of the stone is 0.6138 c.

(B) is correct option.

Explanation:

Given that,

Mass of stone m= 0.6

Relativistic mass = 0.76

We need to calculate the speed

Using formula of rest mass

m_{r}=\dfrac{m_{0}}{\sqrt{1-\dfrac{v^2}{c^2}}}

v^2=(\dfrac{m_{0}^2}{m_{r}^2}-1)c^2

Put the value into the formula

v^2=(\dfrac{0.6^2}{0.76^2}-1)\times c^2

v=\sqrt{0.37673c^2}

v=0.6138c

Hence, The speed of the stone is 0.6138 c.

A disk initially rotated counterclockwise at 1.0 rad/s, but has a counterclockwise angular acceleration of 0.50 rad/s^2 for 2 se
Mumz [18]

Answer:

Initial angular position of the disc is 3 radian

Explanation:

As we know that the angular acceleration of the disc is given as

\alpha = 0.50 rad/s^2

initial angular speed is given as

\omega = 1 rad/s

now we know that angular displacement of the disc is given as

\theta = \omega t + \frac{1}{2}\alpha t^2

\theta = 1(2) + \frac{1}{2}(0.5)(2^2)

\theta = 3 rad

now we have

\theta_f - \theta_i = 3 rad

6 rad - \theta_i = 3

\theta_i = 3 ard
