Answer 1

A seconds pendulum is a pendulum whose period is precisely two seconds; one second for a swing in one direction and one second for the return swing, a frequency of 1/2 Hz.

Answer 2

A seconds pendulum is a pendulum whose period is precisely two seconds; one second for a swing in one direction and one second for the return swing, a frequency of 1/2 Hz.

The time period of a simple pendulum is 2 s. What is its frequency? What name is given to such a pendulum?

A clock which has pendulum made of brass keeps correct time at $3 0^{\circ} C$ . How many seconds it will lose or gain in a day if temperature falls to $0^{\circ} C$ . $(α_{b r a s s} = 1.8 \times 1 0^{- 3} /^{\circ} C^{- 1})$

State the numerical value of the frequency of oscillation of a seconds' pendulum. Does it depend on the amplitude of oscillation?

If a pendulum takes $4 s e c$ to swing in each direction, find the length of the pendulum.

A simple pendulum (whose length is less than that of a second's pendulum) and a second's pendulum starts swinging in phase. They again swing in phase after an interval of 18 second from the start. The period of the simple pendulum is
