Answer:
Photoelectric effect
Explanation:
In the photoelectric effect, when an x-ray strikes on a metal surface, the energy is completely absorbed by the metal. If the energy would be equal to or more than work function of metal, electron ejects out. The kinetic energy of the electron which is ejected depends on the energy of the incident radiation and work function of the metal.
Answer:
warmer
Explanation:
I really think it just gets hot
Answer:
38.87 m/s
Explanation:
Given that the ball is dropped from a height = 77 m
u = 0 m/s
s = 77 m
a = g = 9.81 m/s²
Applying the expression as:
Applying values as:
<u>The speed with which the ball hit the ground = 38.87 m/s</u>
<span>1 pound is equal to .454 kilograms.
115 pounds equals
115 x .454 kilograms = 52.163 kg.
The total dose is equal to the dose per kilograms multiplied by the total mass in kilograms.
6.00mg/kg x 52.163kg = 312.978mg.
The total dose is 313.0 mg</span>
