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:
It takes 266 seconds to melt the ice.
Explanation:
Given data
- Power of the microwave oven (P): 125 Watt
- Heat supplied to the ice (Q): 33,200 Joule
- Time for the melting (t): to be determined
In order to determine the time required to melt the ice, we can use the following expression.
P = Q/t
t = Q / P = 33,200 J/ 125 W = 266 s
It takes 266 seconds to melt the ice.
Answer:
1.227 m
Explanation:
Given that
Minimum wavelength is 410 nm
Maximum wavelength is 750 nm
Grating is 7800 slits/cm
Distance is 3.2 m
To solve this question, we would use the formula
sin θ = λ/d
sin θ = (410*10^-9) / (0.01/7800)
Sin θ = 410*10^-9 / 1.282*10^-6
Sin θ = 0.32 and θ = 18.67 degrees
For the second wavelength = 750 nm
sin θ = [(0.32x750)/410]
sin θ = (240 / 410)
sin θ = 0.5853 or
θ = 35.8 degrees
And finally, the width of spectrum would be
3.2[tan 35.8 - tan 18.67]
3.2 * 0.3833
= 1.227 m
Electrical force is the repulsive or attractive force of attraction between any two charged bodies. it is possible to calculate electric force on anything that runs on batteries or uses a plug. Its net effect can be explained using newtons law of motion like any force.
From the coulombs law; F = k (q1║q2)/ r²
Where k = 9 ×10∧9 N.m².C∧-2, r12= 0.285m, q2= +6μC and q1 = 4.86 nC
substituting values in the equation
the net electrical force acting on the +6ц C charge is 5.4 N.
