Pls mark as brainliest
Like a lot of other things, (gravity, sound, electrostatic force), brightness also decreases as the square of the distance.
When the source moves to a new position that's 4 times as far away, its apparent brightness becomes (1/4^2) its original value.
That's 1/16 .
Acceleration = (change in speed) / (time for the change)
Acceleration = (23 - 5) m/s / 4s = 18/4 m/s² = <em>4.5 m/s²</em>
