DNA of two species is one of the best evidence to tell us how closely related the two species are.
A longitudinal wave is also known as an oscillating wave. These waves affect the medium they are traveling through by disrupting what is either directly in front of behind them as they move.
Answer:
electricity
If a rod is charged it is because of the electrical force acting on it
The frequency and period of any wave are reciprocals.
Frequency = 1/period and Period = 1/frequency .
That means that the product of (frequency) times (period) of any wave is always the same. The product is always ' 1 ', with no unit.
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.
