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.

number 3 is the 3rd one and number 2 is the 4 one and number 1 is the 2nd one
Answer:
k = 5572 N/m
Explanation:
Energy stored in the spring:
1)
Kinetic energy of the car:
2)
Spring force:
3)
Combining equation 1 and 2 and solving for k:
4)
Using equation 3 and solve for x:
5)
Combining equation 4 and 5:
6)
The x position will be "12 m" and the y position will be "-4.9 m".
According to the question,
Along x direction, Initial velocity:
Along x direction, Acceleration is:
Along y direction, Acceleration is:
Time,
→ The X coordinate will be:
=
=
=
→ The Y coordinate will be:
=
=
=
=
=
