Un pendul cu arc oscileaza cu frecventa de 0,25Hz. Cite oscilatii efectueaza acest pendul timp de 10s?

Given:

The frequency of the pendulum (f) = 0.25 Hz.

Total time (t) = 10 s

Concept: Frequency means, the number of oscillation in one second.

Time period is the required time by pendulum to complete one oscillation.

∵ In 1.0 second, number of oscillations = 0.25

∴ In 10.0 second, number of oscillations = (0.25 * 10.0) / 1.0 = 2.5

Hence, the required number of oscillation = 2.5
