A pendulum takes 10 seconds to swing through 2 complete cycles.

AHow long does it take to complete one cycle?
BWhat is its period?
CWhat is its frequency?

Verified Answer :

Answer:

a. 5 seconds

b. 5 seconds

c. 0.2 Hz

Explanation:

a) For 2 complete cycles, time taken is 10 s.

Thus, for 1 complete cycle, the pendulum would take = 10 s÷ 2 = 5 s

b) The time period of a pendulum can be defined as time to complete 1 cycle/oscillation. This is calculated in part a. Thus, time period of the pendulum is 5 s.

c) The frequency of a pendulum can be define number of cycles/oscillations in 1 s. It takes 5 s to complete 1 cycle.

In 1 s, number of cycles = (1 ÷ 5) s⁻¹ = 0.2 Hz.
