Araindrop of mass 3.26 10-5 kg falls vertically at constant speed under the influence of gravity and air resistance. model the drop as a particle.(a) as it falls 115 m, what is the work done on the raindrop by the gravitational force?

Work done by the gravitational force is 37 mJ.

Explanation:

It is given that,

Mass of the raindrop,

It falls from a height of, h = 115 m

It falls vertically at constant speed under the influence of gravity and air resistance. We need to find the  work done on the raindrop by the gravitational force. It is given by :

W = 0.0367 J

or

W = 0.037 J = 37 mJ

So, the work done on the raindrop by the gravitational force is 37 mJ. Hence, this is the required solution.

into the screen

explanation:

the wind is hitting the car into the screen

force required to detach it is given by

charges are taken to be fundamental charge

now we have

so above is the minimum distance at which it will detach
