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`

Instantaneous angle (in radian) between string of a simple pendulum and verical is given by theta = (pi)/(180) sin2pit . Find the length of the pendulum if g = pi^(2) m//s^(2) .

Time period of a simple pendulum only depends on the _______________ of the string.

Obtain an expression for the time period T of a simple pendulum. [The time period T depend upon (i) mass l of the bob (ii) length m of the pendulum and (iii) acceleration due to gravity g at the place where pendulum is suspended. Assume the constant k=2pi ]

State how does the time period of a simple pendulum depend on length of pendulum.

Show that the motion of a simple pendulum is simple harmonic and hence derivean equation for its time period. Find the length of a simple pendulum which ticks seconds. (g=9.8ms^(-2))
