Answer:

A change in speed

Explanation:

Light bends when it moves at a particular angle into a medium that has a different refractive index than the one it was coming from.

This bending is as a result of the change in speed of light as it enters the medium with a different refractive index.

This action is known as Refraction of light.

Refraction depends on the change in speed of light as it changes media and the angle of refraction depends on the angle of incidence of the ray of light and the refractive index of the material.

Whenever light goes from transparent to another medium or from rarer to denser medium or vice versa, it's speed changes and hence light bends.

A heavy turntable, used for rotating large objects, is a solid cylindrical wheel that can rotate about its central axle with neg

scoundrel [369]

Answer:

a) $I = 113.014\,kg\cdot m^{2}$ , b) $m = 2075.556\,kg$

Explanation:

a) The turntable has the following physical model by using Newton's laws:

$F \cdot R = I \cdot \alpha$

The moment of inertia is:

$I = \frac{F\cdot R}{\alpha}$

$I = \frac{(300\,N)\cdot(0.33\,m)}{0.876\,\frac{rad}{s^{2}} }$

$I = 113.014\,kg\cdot m^{2}$

b) The moment of inertia for a solid cylinder:

$I = \frac{1}{2}\cdot m \cdot R^{2}$

The mass of the turntable is:

$m = \frac{2 \cdot I}{R^{2}}$

$m = \frac{(2)\cdot (113.014\,kg\cdot m^{2})}{(0.33\,m)^{2}}$

$m = 2075.556\,kg$

What nonliving materials are important to living things?

Pavel [41]

<span>Nonliving things also have unlimited duration of existence. While living things die and decompose, nonliving things such as rocks, mountains, air and water have existed for millions of years. They may grow, but they do so only by accretion, which is the process of growth by accumulating added layers of matter.</span>
