Question

find the time period of a simple pendulam whose lenght is 144 cm​

Answer 1

Length of pendulum (L) = 1.44 meters
Value of gravitational constant (g) = 9.82 m/s2
Value of the constant pi = 3.142

Now we can substitute these values in the above given equation and obtain the value for time period of the pendulum. The equation is solved below

T= 2 x 3.142 (1.44/9.82)1/2
T= 2 x 3.142 (0.14663951120162932790224032586558)1/2
T= 6.284x 0.38293538776356165840480801488278
T= 2.4063659767062214614158135655234
T= 2.406 sec
