Answer:
option c
Explanation:
K.E=1/2mv(squared)
K.E=1/2x900x80x80
K.E=450x6400=2880000J
convert to KJ=2880000/1000=2880KJ

and

As a result, blue light has a higher energy level than green and red light.
As a result, the surface glows due to the blue LED. The green LED, on the other hand, would not allow the surface to glow as much as the red LED, which has a lower energy level when compared to the green light. As a result, the red LED would not allow the surface to glow as well.
