Third class levers are best described as follows:a) The muscle force and resistive force act on opposite sides of the fulcrum, and the effort required tomove the load is at a mechanical advantageb) The muscle force and resistive force act on opposite sides of the fulcrum, but the effort required tomove the load is at a mechanical disadvantagec) The muscle force and resistive force act on the same side of the fulcrum, with a longer moment arm forthe effort than for the loadd) The muscle force and resistive force act on the same side of the fulcrum, with a longer moment arm forthe load than for the effor

show the diagram then i will answer

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.
