<span><span>-When sunlight strikes a falling drop of water it is refracted, changed indirection, by the surface of the water.</span>
The light continues into the drop and is reflected from the back of the drop to the front. When the beam hits the front it is refracted again and emerges from the drop as the color spectrum that we see in a rainbow.<span>-The water drop acts like a prism to seperate the light into its different wave lengths.</span></span>
Given that,
Mass of a water balloon, m = 1 kg
It comes downward an experience a 4.9 N air resistance as it approaches the ground.
To find,
The acceleration of the water balloon when it experiences this air resistance.
Solution,
Let the acceleration be a.
The net force acting on it will be :
The force is also given by :
F = ma
So, the acceleration of the water balloon is .
