A drop of liquid is broken down into `27` identical liquid drops. If the terminal velocity of original liquid drops is `V_(T)`, then find the terminal velocity of the new liquid drop thus formed.
A big drop of a liquid is spread into 5 identical droplets . In this process.
A small liquid drop of radius R is divided into 27 identical liquid drops. If the surface tension is T, then the work done in the process will be :
Two rain drops of same radius r falling with terminal velocity v merge and from a bigger drop of radius R. The terminal velocity of the bigger drop is
Two exactly simlar rain drops falling with terminal velocity of (2)^(1//3) ms^(-1) coalese to from a bigger drop Find the new terminal velocity of the bigger drop.
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 .
A drop of liquid of diameter 2.8 mm breaks up into 125 identical drops. The change in energy is nearly (S.T. of liquid =75 dynes / cm )
