Answer:
The correct answer is A.
Objects in free fall accelerate due to <u>gravity</u>.
Explanation:
Momentum can help an object to keep its state of motion at a constant velocity when no external force is applied. It can never accelerate the object.
According to the laws of motion, we know that acceleration is produced in a body only when a Force is applied in the direction of motion of body.
During a free fall, only the force of gravity is acting on an object and that too in the direction of its motion. Hence, the acceleration produced in a free falling object is due to gravity.
Answer:
Population inversion, in physics, the redistribution of atomic energy levels that takes place in a system so that laser action can occur. Although absorption and emission of energy is a continuous process, the statistical distribution (population) of atoms in the various energy states is constant. ...
laser inversion is photon that can stimulate the production of other photons of exactly the same wavelength because of stimulated emission of radiation.

Answer:
Density equals mass over volume so 2 divided 500
The brake rotor spins along with the wheel and the stationary brake caliper wraps around the rotor and works through a piston system as to when the brake is applied it pushes brake fluid into the calipers pistons (which is attached to the brake pads) therfore the brake pads are pressed onto the rotating brake rotor thus creating friction gradually or abruptly slowing it down depending on how hard the brake is applied.
