7 0

Answer:

Normally, light travels in a straight path called a ray, however, when passing through clear materials, like water or glass, light bends or turns. As a result, the direction and speed of the traveling light wave will change and the light will appear to bend or change directions.

(Hope this helps!! Btw, I am the first answer.)

You are helping your friend move a new refrigerator into his kitchen. You apply a horizontal force of 275 N in the positive x di

Volgvan

Answer:

f = 347.08 N

Explanation:

The frictional force exerted by the floor on the refrigerator is given as follows:

$f = \mu R = \mu W$

where,

f = frictional force = ?

μ = coefficient of static friction = 0.58

W = Weight of refrigerator = mg

m = mass of refrigerator = 61 kg

g = acceleration due to gravity = 9.81 m/s²

Therefore,

$f = \mu mg\\f = (0.58)(61\ kg)(9.81\ m/s^2)\\$
