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.

find the surface area of the sphere to the nearest square unit. use a calculator.

a. 254 in.2

b. 64 in.2

c. 127 in.2

d. 1,018 in.2

3. dark matter

empty space could also be a simple vacuum
