Question

the fog droplet falls vertically through air with acceleration (a)equal to g (b)less than g (c)greater than g (d) equal to zero

Answer 1

Answer:

answer is

d ) equal to zero

Explanation:

the fog droplet falling vertically is not accelerated at 9.8 m/$s^{2}$

The fog droplet when falling vertically in air experiences "air drag force "

so,

upward force = air drag force

downward force = gravitational force

under these forces the fog droplet will acquire terminal velocity after few seconds.

At this time these two forces will be equal in magnitude and opposite in direction.

so, the net force is zero

$F_{net}$ = 0

m a = 0

which implies      a = 0

therefore acceleration is equal to zero

hope it helps !

Answer 2

Explanation:

d ) equal to zero

Explanation:

the fog droplet falling vertically is not accelerated at 9.8 m/s^{2}s

2

The fog droplet when falling vertically in air experiences "air drag force "

so,

upward force = air drag force

downward force = gravitational force

under these forces the fog droplet will acquire terminal velocity after few seconds.

At this time these two forces will be equal in magnitude and opposite in direction.

so, the net force is zero

F_{net}F

net

= 0

m a = 0

which implies a = 0

therefore acceleration is equal to zero
