Explain given below the time period of the S.H.M. is changed if
Increase the temperature of the bob

What will be the change in the time period of a pendulum if (i) the diameter of the bob is increased (ii) the mass of the bob is increased keeping its diameter constant?

If the time period of an SHM is 2 s, then what will be its frequency?

Prove that the change in the time period t of a simple pendulum due to a change DeltaT of temperature is, Deltat=1/2alphatDeltaT , where alpha = coefficient of linear expansion.

Explain why the resistance of a semiconductor decreases with increase in temperature.

A bob of mass 0.25 kg hung from a ceiling of a room by a string 1 m long is set into oscillation. The speed of the bob at its mean position is 1.5 m/s. What is the trajectory of the bob if the string is cut when the bob is at its mean position.

A bob of mass 0.25 kg hung from a ceiling of a room by a string 1 m long is set into oscillation. The speed of the bob at its mean position is 1.5 m/s. What is the trajectory of the bob if the string is cut when the bob is at one of its extreme positions.
