find the ratio of of time peroid of two pendula whaose lenghths are in ratio of 1:4
The time periods of two simple pendulums of different lengths are the same on two different planets. If the lengths of the two pendulums are in the ratio of 1:9, then the ratio of the accelerations due to gravity on the two planets, most likely, is :
The ratio of frequencies of two pendulums are 2:3, then their length are in ratio
