Question 1057523
.
The pendulum of an antique clock has been damaged and needs to be replaced. If the original pendulum completed one swing 
every 1.5 seconds, how long should the new pendulum be? Use the formula: 

T =2sqrt√L/980
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~


Your formula is <U>WRONG</U>.


The correct formula is T = {{{2*pi*sqrt(L/g)}}},  or  T = {{{2*pi*sqrt(L/981)}}},  where  L  is the pendulum length in centimeters, g = 981 cm/s^2.
