T = 2pi*sqrt(L/g).
T = 1 sec. = Period.
L = Length in cm.
g = 980 cm/s^2.
The period of a pendulum is the time it takes to swing from left to right and back again.
The period T seconds, of a pendulum is directly proportional to the square root of its length, Lcm.
When L=25, T=1
Find a formula for T in terms of L.
