Answer 2

The time period of a simple pendulum is $T=2.406sec$.

Step-by-step explanation:

Given:

The length of the simple pendulum is 144cm.

To find:

To find the time period of a simple pendulum.

Formula used:

The time period of a simple pendulum $T=2\pi \sqrt{\frac{l}{g} }$

where l is the length and g is gravitational.

Solution:

The gravitational constant (g) has a value of  $g=9.82m/s^{2}$.

The value of the constant pi is $\pi =3.142$

$T=2\times3.142\sqrt{\frac{144}{9.82} }$

$T=6.284\times0.382$

$T=2.406$

Hence, the time period of the simple pendulum is$T=2.406sec$
