creative question:
fall on A drop of water of 1 ong the ground with a velocity of 15 met above forom the ground against air resistance [g= 9.83 m52] from 20m a. What is called vernier constants b. Why it is difficult to climb up to the mountain than coming down? Explain it. a Determine the time to fall the drop of water to the ground. The weight of the drop of tooden is than the resistive force of airn Explain mathematically d. more​
