Sagot :
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.
