Question 195786: the time it takes for a pendulum to complete one full swing is called its period. the period of a pendulum is directly related to the square root of the length of the pendulum. if the period is 1.5 seconds when the pendulum is 2 feet long, what is the period for a 4 foot long pendulum?

1.5/sqrt2=x/sqrt4
1.5*sqrt4=xsqrt2
1.5*2=xsqrt2
3=1.414x
x=3/1.414
x=2.12164 sec. is the period of a 4 foot long pendulum.
