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.

Answer:
The moment of inertia is
Explanation:
From the question we are told that
The length of the rod is
The mass of the rod is
The distance of the center of mass from the pivot is
The period of the rod's motion is
Generally the period of the motion is mathematically represented as
Where is the moment of inertia about the pivot so making the subject of formula
substituting values
The output waveforms after passing through the transformer actually depend on the type of transformer used. It could either be a step-up transformer (steps voltage up), or a step-down transformer (steps voltage down). Both transformers have an output voltage in a form of a sine wave.
Answer:
L
D
Explanation:
At Y, horizontal force is greater than downward force so E or L. However L seems to be more appropriate since horizontal force in L is less than E
At Z, horizontal force is less than downward force so D
Answer:
F= 9492.12 N
Explanation:
Given that
mass, m = 1598 kg
Initial velocity ,u= 0 km/h
Final velocity v= 93.9 km/h
v =26.08 m/s
Distance ,d= 57.2 m
We know that
v² = u² + 2 a d
a=acceleration
u=initial velocity
v= final velocity
d=distance
26.08²= 0² + 2 x a x 57.2
a= 5.94 m/s²
We know that
Force = mass x acceleration
F= m a
F= 5.94 x 1598 N
F= 9492.12 N
