Work = Force * distance
Work = 20 N * 10 m = 200 Nm
Work = 200 Joules.
Answer:
Distance between them increase
Explanation:

where
is the initial velocity which is zero here
is time taken,
is acceleration due to gravity
the position of first drop after time
is given by

the position of next drop at same time is

distance between them is
is 
from the above the difference will increase with the time
Answer:
Divide by 3
Explanation:
In order to estimate the distance traveled by a lightening flash in kilometers, we follow these simple steps:
