Define the length of pendulum.

For simple pendulum, T = 2pi sqrt((l)/(g)) where T is the periodic time and l is the length of pendulum. If there is 4% error in the measure of periodic time then find the error percentage in the length of pendulum.

While measuring the acceleration due to gravity by a simple pendulum , a student makes a positive error of 1% in the length of the pendulum and a negative error of 3% in the value of time period . His percentage error in the measurement of g by the relation g = 4 pi^(2) ( l // T^(2)) will be

The bob of a pendulum is released from a horizontal position. If the length of the pendulum is 1.5m, what is the speed with which the bob arrives at the lowermost point, given that it dissipated 5% of its initial energy against air resistance?

The angle made by the string of a simple pendulum with the vertical depends on time as theta=pi/90sin[(pis^-1)t] . Find the length of the pendulum if g=pi^2ms^-2

The bob of mass 50 gm of a pendulum is released from a horizontal position A as shown in the figure . .If the length of the pendulum is 1.5 m , what is its kinetic energy at the lower most point B ? (g = 10 m/(s^(2)))

The bob of pendulum is released from a horizontal position . If the length of the pendulum is 1.5 m ,what is the speed with which the bob arrives at the speed with which the bob arrives at the lowermost point , given that it dissipated 5 % of its intial energy against air resistance ?

If the length of second pendulum becomes (1)/(3) what will be its periodic time?

Statement-1 : Pendulum clocks go slow in summer and fast in winter. Statement-2 : The length of the pendulum used in clock increases in summer.
