Aray of light is traveling from water into a diamond. upon hitting the diamond, a light ray bends toward the normal. with this information, what can you say about the speed of light as it passes from water into a diamond?
a.) the speed increases
b.) the speed decreases
c.) the speed drops to zero
d.) the speed does not change

the correct answer is b, the speed decreases

The answer is: B.) the speed decreases.

Explanation:

When the light passes from one medium to another, its speed changes.

The light is affected by the medium it passes through, so that the denser the medium is, the lower the speed of light. When crossing a diamond, for example, which is a very dense medium, the speed of light is reduced by a factor of 2,417.

The answer is: B.) the speed decreases.

force is mass*acceleration.

we have a very small mass: 11.4*0.001 kg

if we want 0.035n of force, we need an acceleration:

0.035 = 11.4*0.001*a

a = 0.035/(11.4*0.001) m/s^2

b. lifting dumbbell weight at 20-degree angle from the body after a 45-degree angle
