Answer:
E = 4000 N/C
Explanation:
Given the following data;
Force = 0.080 N.
Charge, q = 20 microcoulomb = 20 * 10^-6 = 2 * 10^-5 Coulombs
To find the electric field strength;
Mathematically, the electric field strength is given by the formula;
Electric field strength = force/charge
Substituting into the formula, we have;
E = 0.080/0.00002
E = 4000 N/C
Force, F = ma
Where m = mass in kg, a = acceleration in m/s², Force, F is in N.
F = ma
2000 = m*2.2
2.2m = 2000
m = 2000/2.2
m ≈ 909.09
Mass is ≈ 909.09 kg.
The magnitude of the applied force is 3369.57 N.
<h3>What is Force?</h3>
Force can be defined as the product of mass and acceleration.
To calculate the magnitude of the applied force, we use the formula below.
Formula:
- P = Fv................ Equation 1
Where:
- P = Power of the electric motor
- F = Applied force
- v = Velocity
Make F the subject of the equation
- F = P/v................. Equation 2
From the question.
Given:
- P = 31 kW = 31000 W
- v = 9.2 m/s
Substitute these values into equation 2
- F = 31000/9.2
- F = 3369.57 N
Hence, the magnitude of the applied force is 3369.57 N.

Answer:
Waning gibbous.
Explanation:
The same side that you see in one place of the continent at night, you will also see in other place on earth, regardless of the hemisphere. There is however a slight difference, but not ecognizable to the human eye thus Waning Gibbous will also be seen everywhere else in the night sky that night.
