Answer:

Explanation:
= Intensity of unpolarized light = 
= Angle of the filter = 
Intensity of light is given by

The intensity of light detected by the camera is 
Answer:
a. 45 N. / b. 0.08 m/s^2. / c. 102 N
F = ma
F = 15(3)
F = 45 newtons
F/m = a
20/250 = a
0.08 m/s^2 = a
R = ma
R =1.5(68)
102 N
