Answer
Compound pendulum
Reason — Compound pendulums have a more constant period of oscillation over a wider range of amplitudes, making them suitable for use in clocks.

Figure below shows the reading obtained while measuring the diameter of a wire with a screw gauge. The screw advances by 1 division on main scale when circular head is rotated once.
Find —
(i) pitch of the screw gauge,
(ii) least count of the screw gauge, and
(iii) the diameter of the wire.
A screw has a pitch equal to 0.5 mm. What should be the number of division on its head so as to read correct up to 0.001mm with its help?
The time taken to complete one oscillation is called:
- Frequency
- Amplitude
- Time period
- Acceleration
The number of oscillations made in one second is called :
- Amplitude
- Time period
- Frequency
- None of these
