  12. What is meant by longitudinal and mechanical waves? Answer: Longitudinal waves are waves in which the particles of the medium move parallel to the direction of the wave, while mechanical waves are waves that require a material medium for propagation, such as sound waves.

  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.

Answer: When the number of turns in the primary coil of a transformer is greater than the number of turns in the secondary coil, the voltage is stepped up (increased). Conversely, if the secondary coil has more turns, the voltage is stepped down (decreased).
