Apendulum with a length of 1.5 meters is released from an angle of 20 degrees. what is the period and frequency of this pendulum?

The period and frequency of this pendulum are 2.457 s and 0.407 Hz.

Explanation:

Given that,

Length = 1.5 m

Angle = 20°

We need to calculate the period

Using formula of period

Where, T = time period

g = acceleration due to gravity

l = length

Put the value into the formula

We need to calculate the frequency

Put the value of T

Hence, The period and frequency of this pendulum are 2.457 s and 0.407 Hz.

it is very well related to a lot of things but with my limited knowledge i can confidently say that the answer is space.

the answer is b, have negligible mass
