Question

pendulum A makes 14 oscillation in five seconds and pendulum B makes 10 oscillation in 3 seconds . Which has higher frequency ? Express the frequency of each pendulum in hertz

Answer 1

^_^



For A ,


Number of oscillation = 14

Time = 5sec

So ,

frequency = 14 / 5

= 2.8


For B ,

Number of oscillation = 10

Time = 3 sec


Frequency = 10 / 3


= 3.333....

So ,


B has higher frequency than A

Answer 2

Answer:PENDULUM A

Number of oscillation=14 Oscillation

Total time is taken=5 seconds

Frequency=number of oscillations per second

=Number of oscillation/time

=14/5

=2.8 per second or 2.8 HZ

PENDULUM B

Number of oscillation=10 oscillation

Total time is taken=3 seconds

Frequency=number of oscillation /time

=10/3

=3.33 per second or 3.33 HZ

Explanation: Pendulum B has a higher frequency than Pendulum A
