Answer:
when the momentum of the vehicle moving at 30 km/h is higher than the one from the vehicle moving at 60 km/h
Explanation:
It's much harder to stop a freight truck moving at 30 km/h than a hot wheels car moving at 60 km/h.
Explanation:
Given that,
Potential = 75 kV
Exposure = 200 mR
Time = 0.2 sec
We need to calculate the x-ray fluence during this chest x-ray exam
Using formula of fluence

Put the value into the formula


We need to calculate the energy fluence
Using formula of energy fluence


We need to calculate dose -equivalent delivered to the bone, muscle, and fat
Using formula of dose

Where, D = dose
E = energy
t = time
Put the value into the formula


Hence, This is the required solution.
