You observe that the passage of a particular thundercloud over-head causes the vertical electric field strength in the atmosphere, measured at the ground, to rise to 3000 n/c (or v/m). (a) how much charge does the thundercloud contain, in coulombs per square meter of horizontal area? assume that the width of the cloud is large compared with the height above the ground. (b) suppose there is enough water in the thundercloud in the form of 1 mm diameter drops to make 0.25 cm of rainfall, and that it is those drops that carry the charge. how large is the electric field strength at the surface of one of the drops?

its c i just checked it

air exerts forces on falling objects near earth’s surface.

explanation:

the term 'free falls' refer to object that are falling towards the earth, in a situation in which gravity is the only force acting on the object.

for an object in free fall, the acceleration is constant (g, the gravitational acceleration), and so the velocity of the object constantly increases.

for objects near earth's surface, there is always another force acting on the object: the resistance due to the air. this force is opposed to the direction of fall of the object, and it is proportional to the velocity of the object, so as the object falls down, this force increases up to a point when it balances the force of gravity, and the object continues its motion at constant velocity (called terminal velocity). since in this case gravity is not the only force acting on the object, we are not in a situation of free fall.

force tends to be low and long diustance masses are high
