Response Details:
  The time period of the seconds pendulum is
            T = 2π√(L/g)
          
   The length of the pendulum is
                    L = (T2 g)/(4π2)

  Here T = 0.600 s
           g =9.80  m/s2

Substitute the values for L.
I hope this helps! Best of luck with the rest of your coursework.

Response Details:
T = 2π √(L/g)  ,  here T is period, L is the length
=>L = g*(T/2π)2 = 9.8m/s2 *(0.600s/2*3.14)2 = 0.089 m
the length is 0.089m
