Hi I have those 2 problems:(adsbygoogle = window.adsbygoogle || []).push({});

A typical cloud contains droplets of water with an average radius of .5 * 10^-4m.

how many droplets are needed for a cloud that provides a rainfall of .5 cm.

( the answer must be 1*10^21 droplets)

for this second problem I don't know how to find two equations:

A force F acting on a body of massma distancerfrom some origin has a magnitude of F=(A*m*exp(h*r))/r^4, whereAandhare both constants.

Given that the force has dimensions kilogram-meter per seconds squared, what are the dimensions of bothAandh.

Please can I have some help or suggestions for those problems?

Thank you very much
