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.
the more pressure put on the string, the more frequency and higher pitch.
B. Thermal energy is the energy that warms the earths surface.
the answer Is C. ,, thank you :)
