Aclosed surface is constructed in the space between two large parallel metal plates, where there is a constant electric field e. the magnitude of the field is |e| = 1480 n/c. the numbers (1), (2), and (3) in the simulation label small increments of area of 1.5 cm2 on the surface. the direction of each increment is defined to be the direction of a vector out of the surface and perpendicular to the increment's surface area. with that definition assume the direction of the first increment î”a1 is 65° from the direction of e, that the second increment î”a2 is oriented 90° from the direction of e, and that the third increment î”a3 is oriented 135° from the direction of e. find the flux through each of the three increments of area

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.
