Solid phase. The atoms are tightly packed and vibrate.
The number of protons that strike the tumor each second is
protons.
<u>Given the following data:</u>
- Energy of proton =
Joules.
- Current = 84 nA to A =
Ampere.
- Energy of total dose =
Joules.
<u>Scientific data:</u>
- Charge of proton =
C.
To determine the number of protons that strike the tumor each second:
<h3>How to determine the number of
protons.</h3>
Mathematically, the quantity of charge per unit time is given by this formula:

<u>Where:</u>
- N is the number of protons.
- t is the time measured in seconds.
- e is the charge of protons.
Substituting the parameters into the formula, we have;
protons.

Answer:
Ф = 239.73 rad
Explanation:
α = 12 + 15×t
W = ∫α×dt
= ∫(12 + 5×t)×dt
= 12×t + 2.5×t^2
then:
Ф = ∫W×dt
= ∫(12×t + 2.5×t^2)dt
= 6×t^2 + 5/6×t^3
therefore the angle at t = 4.88s is:
Ф = 6×(4.88)^2 + 5/6×(4.88)^3
= 239.73 rad
