<u>Mass</u>
- Mass is measured in kilograms.
- Mass does not change when gravity changes.
- Mass is the amount of matter in something.
<u>Weight</u>
- Before I answer, we have to know weight formula. Weight = mass × acceleration due to gravity.
- Therefore, weight is measured in Newtons.
- Weight changes when gravity changes. This is because weight is dependent on acceleration due to gravity.
- Weight is a gravitational force.

Answer: Pretty sure the answer is B but this kind of looks like a test question.
Explanation:
The magnitude of average current is 2.02 * 10⁻¹⁴ A.
<h3 /><h3>What is current?</h3>
A stream of charged particles, such as electrons or ions, travelling through an electrical conductor or a vacuum is known as an electric current. The net rate of electric charge flowing through a surface or into a control volume is how it is calculated.
Number of electrons passing per second = 4910/ 0.0662 = 74169.18
Number of proton passing per second = 3485/0.0662 = 52643.50
current due to electrons,
I = ne
= 74169.18 * 1.6 * 10⁻¹⁹
= 1.18 * 10⁻¹⁴ A
current due to protons,
I = ne
= 52643.50 * 1.6 * 10⁻¹⁹
= 0.84 * 10⁻¹⁴ A
total current I = Ie + Ip
I =( 1.18 + 0.84 ) * 10⁻¹⁴ A
I = 2.02 * 10⁻¹⁴ A

Light travels approximately 186,000 miles per second in empty space.
Then, if you do the math, it goes 5.88 Trillion miles per year.
