Answer:
3.7m/s^2
Step-by-step explanation:
T is given as 3.27 seconds
L= 1m
we have to find g just put values in given formula
3.27s=2pi(sqrt(1m/g))
3.27s/2pi=(sqrt(1m/g))
0.520s=(sqrt(1m/g))
Taking square on both side to eliminate square root
0.27085s^2=1m/g
Multiply with g on both sides
0.27085 s^2*g=1m
Divide both sides with 0.27085
g=1m/0.27085s^2
g=3.7m/s^2
