Missing graph. I attach it in the answer.
In a uniformly accelerated motion, the velocity at time t is given by:
where a is the acceleration and t is the time.
Given the previous equation, if we plot v(t) versus t, we find a straight line; moreover, a (the acceleration) represents the slope of the curve.
Looking at the graph, we see that when the time goes from 10 s to 20 s, the velocity increases from 4 m/s to 6 m/s. Therefore the slope of the curve is
and this corresponds to the acceleration.
So, the correct answer is <span>0.2 m/s2.</span>

Answer:
Distance between them increase
Explanation:
The position S of the water droplet can be determined using equation of motion
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
