Explanation:
Terminal velocity is given by:
Here, m is the mass of the falling object, g is the gravitational acceleration, 
is the drag coefficient, 
is the fluid density through which the object is falling, and A is the projected area of the object. in this case the projected area is given by:
Recall that drag coefficient for a horizontal skydiver is equal to 1 and air density is 
.
Without drag contribution the motion of the person is an uniformly accelerated motion, thus:
Answer:
it b
Explanation:
bc A water droplet falling in the atmosphere is spherical
The blades that spin around in the fan, because they are flat and produce work
Answer:
particles
Explanation:
in liquids, particle are close together
