Energy can be transformed from one kind to another. an electric motor transforms electrical energy into mechanical energy while an electric generator does the opposite. true / false.

True

Explanation:

It is a true statement as the motor transforms the electrical energy given to it into mechanical energy. When electrical energy in forms of current and voltage is given to motor then its shaft rotate and torque produced and mechanical energy obtained.

Similarly in case of generator when we move its prim mover by any mechanical means then electrical energy is produced

So this is a true statement

answer; /// i believe that the correct answer is (c)

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.
