Question

a pendulum completes 2 oscillations in 5 seconds (a)what is the time period(b)g=9.8ms^2 find its length ​

Answer 1

Step-by-step explanation:

Time period= (oscillation per second) ^-1

=(2/5) ^-1 = 5/2= 2.5 s

Length= t^2/ 4x^2×g= (2.5)^2/4x^2×9.8=1.55

Answer 2

Answer:

because a = 2.5s and b=1.55m
