The sun or solar energy is the most reliable source of energy on Earth.
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:

Explanation:
The number of oscillation per unit time is called frequency of a wave while the distance between two consecutive crests and the trough is called its wavelength.
The wavelength of a wave is given by :

If frequency is doubled, f' = 2f




So, when the frequency is doubled the wavelength of a wave on the string becomes half.
Temputure is outside of earth like around us but internal is inside of the earth
