Answer:
The answer is
Explanation:
The amount of energy is not enough to apply the relativistic formula of energy , so the definition of energy in this case is
.
From the last equation,
where
and the mass of the neutron is
.
Then
the equivalent of the speed of light.
Answer:hmm not sure on that one
Explanation:
Answer:
the angle of incident is 40°
Explanation:
NQ is the normal to the mirror, therefore
angle NQA =90°
PQA = 50°
incident angle = NQA - PQA
90°- 50° = 40°
note that the angle of reflection is equal to the angle of incident
