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

Answer:
3.75 × 10⁻⁸ N
Explanation:
Given:
Intensity of the electromagnetic wave, I = 150 W/m²
Sides of the board = 25 cm (= 0.25 m) and 30 cm (= 0.30 m)
therefore,
the area of the rectangular box, A = 0.25 × 0.30 = 0.075 m²
Now,
force exerted on the card by the radiation, F = 
here,
C is the speed of the light = 3 × 10⁸ m/s
on substituting the respective values, we get
F = 
or
F = 3.75 × 10⁻⁸ N
Force of gravity on an object = (mass of the object) x (acceleration of gravity)
12.0 Newtons = (mass of the object) x (9.8 m/s²)
Mass of the object = (12.0 Newtons) / (9.8 m/s²)
Mass of the object = 1.22 kilograms
Psychoanalysis considers introspection and examines the subconscious.
Answer:
D. Test a piece of treated iron and a piece of untreated iron under the same conditions.
Explanation:
A controlled experiment is defined as an experiment where the experimenter or the researcher tries to test or experiment his result by changing one variable at a time and keeping the other factors under the same conditions and sees how it effects the result.
The factors which can be changed in an experiment is called its variables.
In the context, testing a piece of treated iron as well as a untreated piece of iron under the same working conditions forms a controlled experiment.
