Rain drops fall from a great height under gravity. Check the correct statement

It is a common observation that rain clouds can be at about a kilometer altitude above the ground. If a rain drop falls from such a height freely under gravity, what will be its speed? Also calculate in km/h. (G = 10 m//s^2) .

It is a common observation that rain clouds can be at about 1 km altitude above the ground. If a rain drop falls from such a height freely under gravity, then what will be its speed in km h^(-1) ? (Take g = 10 m s^(-2) )

A ball is dropped from a tower of height h under gravity. If it takes 4s to reach the ground from height h/2 , then time taken by it to reach from h to h/2 is nearly:

Eight identical droplets, each falling under gravity in the earth's atmosphere with terminal velocity v , combine to form a single drop. The terminal velocity of single drop and drag force on it are calculated. Find the correct statement from the following.
