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.

<span>Fossils provide solid evidence that organisms from the past are not the same as those found today; they show a progression of evolution. Scientists calculate the age of fossils and categorize them to determine when the organisms lived relative to each other. Hope this helps</span>
Answer:
Here is the solution hope it helps:)
Answer:
Explanation:
Given
Initial velocity of ball 
height of window 
Using Equation of motion
where u=initial velocity
t=time
a=acceleration
As ball is already is at a height of 20 m so
(b)highest point is obtained at v=0
where
v=final velocity
u=initial velocity
a=acceleration
s=displacement
Highest Point will be 
(c)Time taken when the ball hit the ground i.e. at Y=0
impact velocity
