Question

a pendulum a oscillates 16 times in 4 seconds and pendulm b oscilates 40 time in 8second the number of osccilation in time period equal to taken in b to complete 10p osccilation

Answer 1

Answer:

Explanation:

A pendulum makes 40 oscillations in 4 seconds. find its time period and frequency.

Given that 40 oscillations are made by the pendulum for 4 sec.

So, It makes 10 oscillations are made by the pendulum for 1sec.

We know that the number of oscillations made per second (10 oscillations per second ) is called its frequency

∴ Frequency = 10 Hz

Time period = 1/ Frequency

Time period = 1/ 10

Time period = 0.1 sec
