None of these are a good definition; a good definition would be "the maximum velocity that an object can fall at." however the best answer out go those is c. the constant velocity of some falling objects.

Answer:

c. the constant velocity of some falling objects.

Explanation:

When a body is dropped (or thrown up) vertically and only the force of gravity acts on it, it is said that the body carries a free fall motion. Free fall is a special case of uniformly varied rectilinear motion.

Therefore, the MRUV formulas will be applied, with a modification: The acceleration of the bodies in free fall is the acceleration of gravity represented by the letter g and is, on Earth, approximately equal to 9'8 m / s2.

<u>An object that falls</u>, initially gains speed. When gaining speed, the resistance force of the air will increase, which is nothing more than the result of collisions with the air molecules suffered by any object that travels through a layer of air. The greater the number of molecules with which it collides, the greater the resistance. Consequently, the air resistance depends on the speed of the falling object and its surface (its shape).

The object will continue to accelerate until the air resistance force is large enough to compensate for the force of gravity. At that time the object will continue to fall but will do so with <u>constant speed</u> (terminal velocity).

Hi, your question was incomplete, hence I am writing down the complete question below.

Q)The displacement x of a particle of rest mass m0, resulting from a constant force m0g along the x-axis, is

x= c2/g{[1+(gt/c)2]power0.5-1}

including relativistic effects. Find the displacement x as a power series in time t. Compare with the classical result.

Explanation:

Efficiency is a way of describing the amount of useful output a process or machine can generate as a percentage of the input required to make it go. In other words, it compares how much energy is used to do work versus how much is lost or wasted to the environment. The more efficient the machine, the less energy wasted.

For example, if a heat engine is able to turn 75 percent of the fuel it receives into motion, while 25 percent is lost as heat in the process, it would be 75 percent efficient. Out of the original 100 percent of the fuel, 75 percent was output as useful work.

the equation:

energy efficiency =useful output energy/total input energy
