Explanation:
Radiation refers to energetic particles that deposit their energy, often harmful, into tissue. The particles can be either protons, neutrons, electrons (beta), alpha or
gamma.
Neutron radiation is generated by a fission process, which can release neutrons as a product of fission, and by radioactive decay. Within tissue, neutrons will predominantly lose energy in collisions with protons in the nuclei of hydrogen atoms, in body water. The neutron will strike the proton and knock it out of its position in the atom causing ionization among nearby atoms. This ionization damages the cells in which it occurs. Since this damage occurs in a localized area, is harder for the cells to recover from it, and they are more likely to die or become abnormal potentially resulting in cancer.

Explanation:
It says “Momentum before the collision is equal to momentum after the collision.” Elastic Collision formula is applied to calculate the mass or velocity of the elastic bodies.

Answer:
See answers below
Explanation:
vf = vi + gt
0 = (120sin55°) + (-9.8)t
t = 12.2 s
12.2 x 2 = 24.4 s
x = (vi)t + (1/2)at²
x = (120cos55°)(24.4) + 0
x = 64.79 m
a.
vf = vi + gt
0 = (120sin55°) + (-1.6)t
t = 74.98 s
74.98 x 2 = 149.96 s
x = (vi)t + (1/2)at²
x = (120cos55°)(149.96) + 0
x = 398.18 m
<span> An electromagnet is a current-induced magnet. The basic setup is an electrical current circulating around some magnetizable material, such as an iron rod. The current and number of times the current circulates around determine the magnetic strength. Therefore, the same things that strengthen a current are the same things that strengthen an electromagnet.
</span><span> As current runs through a straight wire, a circular magnetic field is generated around it. When a wire is made into a circle, the current generates a magnetic field parallel to its axis. If you pile loops on top of each other, as in a coil or solenoid, you increase the magnetic field strength.</span>
