Does voltage flow in a circuit? Explain

alekssr [168]

Answer:

Voltage is the measure of specific potential energy (potential energy per unit charge) between two locations. ... When a voltage source is connected to a circuit, the voltage will cause a uniform flow of charge carriers through that circuit called a current.

In proton beam therapy, a beam of high-energy protons is used to kill cancerous cells in a tumor. In one system, the beam, which

Thepotemich [5.8K]

The number of protons that strike the tumor each second is $1.75 \times 10^8$ protons.

<u>Given the following data:</u>

Energy of proton = $2.8 \times 10^{-11}$ Joules.

Current = 84 nA to A = $84 \times 10^{-9}$ Ampere.

Energy of total dose = $3.4 \times 10^{-3}$ Joules.

<u>Scientific data:</u>

Charge of proton = $1.602 \times 10^{-19}$ 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:

$Q =It=Ne\\\\N = \frac{Q}{e}$

<u>Where:</u>

N is the number of protons.

t is the time measured in seconds.

I is the current.

e is the charge of protons.

Substituting the parameters into the formula, we have;

$N=\frac{2.8 \times 10^{-11} }{1.602 \times 10^{-19}} \\\\N = 1.75 \times 10^{8}$ protons.

ankoles [38]

Answer:It depends on the initial velocity of the projectile and the angle of projection. The maximum height of the projectile is when the projectile reaches zero vertical velocity. ... The horizontal displacement of the projectile is called the range of the projectile and depends on the initial velocity of the object
