The format of an Ethernet frame includes a destination address at the beginning which contains the address of the device which is sending the frame. And, the source address tells us which station the information is received from. </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
The car accelerated at around ~5.7 m/s
The tip of the fan moves through the outer side of the circle.
So it moves a distance of perimeter of circle in one revolution.
Perimeter of circle = 2
r, where r is the radius of circle.
In this case radius of circular motion = 0.19 meter
So perimeter of circle = 2
*0.19 = 0.38
= 1.194 m
So distance does the tip move in one revolution = 1.194 meter
