A ray of light strikes a plane mirror at an angle of incidence of 60°, is reflected from the mirror and then strikes a second plane mirror placed so that the angle beftween the mirrors is 45°. The angle of reflection at the second mirror, in degrees, is A 15
B 25
C 45
D 65
E 75
plz help me guys ASAP!

60 - 45 = A. 15

Explanation:

Subtracted because the plane mirror at an angle is incidence of 60°, so then in order to find the value it would be 60-45 and not adding it or dividing and multiplying to find the value thus the answer is 15.

the current is 0.6

voltage ÷ resistance = current

so 12 ÷ 20 = 0.6

it is a negative acceleration
