Prove that WT/Q2 = T2-T1/T2​

Alfred pushes on a heavy box, but cannot move it. the box has a lot of inertia motion friction gravity

Is the time in tennessee the same as florida

The period of a pendulum varies directly as the square root of the length of the pendulum and inversely as the square root of the acceleration due to gravity. find the period when the length is 144 cm and the acceleration due to gravity is 980 cm per second squared, if the period is 7pi seconds when the length is 289 cm and the acceleration due to gravity is 980 cm per second squared.
