Question

in the simple pendulum experiment the length of the pendulum is 19.6 ×10 ki power -2 metre. the time period is 1.91 sce. write the value of the acceleration due to gravity to correct signification figure and round it off.​

Answer 1

Answer:

Given that L = 19.6 ×10^-2 m and T = 1.91 s g = ?

.:g  = 4 pie^2. L

            T

g = 4 pie^2 . (19.6 ×10^-2  )

               (1.91)

.: g = 4.1 m/s^2 = 4 m/s^2

Explanation:

Since T = 2 pie. square root of L/g
