13. What happens when the length of a body becomes double, then tension becomes? Answer: When the length of a body becomes double while keeping other factors constant, the tension in the body remains the same if it is under uniform stretching.

14. What is tension in the string? Answer: Tension in a string is the force transmitted through the string when it is pulled at both ends. It is a pulling force that acts along the length of the string.

15. When kinetic energy becomes maximum at the extreme position, then the equation becomes? Answer: When kinetic energy becomes maximum at the extreme position in simple harmonic motion, it is equal to the potential energy, and the equation becomes “K.E = 0.5 * m * ω^2 * A^2,” where “m” is mass, “ω” is angular frequency, and “A” is amplitude.
