Question

Speed of water coming out of a small hole made in the bottom of a bottle filled with water
decreases with time. Why?

Answer 1

Explanation: It is due to pressure. The deeper we go into the water, the more pressure increases. And more the water is, more pressure there will be. As the time goes on, the water's level gets lesser and lesser (as it is flowing out through the hole), thus, the pressure decreases. So as the pressure decreases, the speed of the water flowing out will also decrease.
