Answer 1

A ll the The objective of this experiment is to determine the time period of a simple pendulum. Period of a simple pendulum. the time measured in seconds for the pendulum bob to go from one extreme position to the cather and back again : the time it takes to complete one cycle. T=27L : here T= time period - L = length of pendulum g= acceleration due to grauity. The size or angle of the are the pendulum is displaced from equilibrium, it is measured in degrees and then converted to radian o amplitude Ans 5 Anso 7 fequilibrium position period of a simple pendulum depends on length of pendulum (4 and acceleration due to gravity (g). TA VE ; T&T True False, it also depends on acceleration to gravity. Ars Aus due I

Ansis! Since TX VE = T = K VE Now, 4 L=4L T = K JUL = 2 k VZ Newperiod 1-2 Corresponding T i-e. time period becomes I to length L. {2 times of original.
