Hello!
What Deshawn notices is that the volume of the bubbles increase as they get closer to the surface of the water.
This occurs because of the Boyle's Law. That Law states that when pressure decreases at constant temperature (like in water), the volume of a gas increases (
).
What is happening is that as the bubbles get closer to the surface of the water, the pressure on them decreases, causing their volume to increase, and that is seen by the increase in the size of the Bubbles that Deshawn noticed.
Have a nice day!

Answer:
It will take 30 seconds to reach the ground, and it will be travelling at 294 m/s when it does so. This means that its average velocity was 147 m/s.
Explanation:
Since the initial velocity of a dropped object is 0, we can make this the equation:
The final velocity can be calculated with the formula:
Once again, since there is no initial velocity:
Since the initial velocity is 0, the average vertical velocity is 294/2=147 m/s.
Hope this helps!
