Twenty seven identical rain drops colaese to form a big rain drop. If this rain drop travels with terminal velocity of 18 `ms^(-1)`, what is the terminal velocity of each small rain drop?

Eight rain drops of radius 1mm each falling downwards with a terminal velocity of 5 cm s^(-1) collapse to form a bigger drop. Find the terminal velocity of bigger drop.

Eight raindrops each of radius R fall through air with teminal velocity 6 cm s^(-1) . What is the terminal velocity of the bigger drop formed by coalescing these drops together ?

Six small raindrops each of radius 1.5 mm, come down with a terminal velocity of 6 cm s^(-1) . They coalesce to form a bigger drop. What is the terminal velocity of the bigger drop?

Two drops of the same radius are falling through air with a steady velcoity of 5 cm s^(-1). If the two drops coalesce, the terminal velocity would be

If n identical water droplets falling under gravity with terminal velocity v coalesce to form single drop which has the terminal velocity 4v. Find the number n .

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.

Twenty seven similar mercury drops are falling through water with terminal velocity 4 cm/s. If the drops combine to form a single drop, then terminal velocity of this bigger drop in water will be

Eight equal drops of water are falling through air with a steady velocity of 0.1 ms^(-1) combine to form a single drop, what should be the new terminal velocity.

n drops of water, each of radius 2 mm , fall through air at a terminal velocity of 8 cms^(-1) If they coalesce to form a single drop, then the terminal velocity of the combined drop is 32 cms^(-1) The value of n is

Eight equal drops of water are falling through air with a steady velocity of 10 cms^(-1) . If the drops combine to form a single drop big in size, then the terminal velocity of this big drop is
