A raindrop with radius R=1.5mmfalls from a cloud that is at height h=1200 mabove the ground. The drag coefficient C for the drop is 0.60. Assume that the drop is spherical throughout its fall. The density of water Pwis1000 kg/m',and the density of air P, iso.0012 gm/cm. (a) What is the terminal speed?

the moving of the box is a result of centripetal force. think of that  as a car or a truck in this case creates a turn, the force of friction performing upon the turned wheels of the car runs centripetal force obligatory for circular motion for the things inside it.

the answer is the last option

explanation:

because in order to know what the molecule is you need to know how many atoms of each element are in the molecule.
