fredd [130]

cause an object to accelerate in a direction opposite to the unbalanced force

Explanation:

An unbalanced force is defined as any force that causes an object to accelerate in a direction opposite to the unbalanced force.

The unbalanced force is the net or resultant force describe in newton's second law of motion.

In the first law, it is the external force that causes the motion of a body to change.

Unbalanced forces can cause body to either accelerate in the direction of the force or in an opposite direction of the force.

For photons of 50 keV, 500 keV, and 5 MeV, what will be the most likely init interaction with tissue?
love history [14]

Answer:

50 KeV

Explanation:

50 KeV will be the most likely initial interaction with tissue.

Because Higher the energy lesser will the interaction with tissues, Because it will penetrate through tissue more easily in a very lesser time Whereas the photon with least energy will take more time to penetrate through the tissue, hence, higher interaction with tissue.
