How can i solve this Chemistry question ?

Question

please help i am so confused ,,, how can you solve this problem

T= 2π (√L/G) and L= 0.5 and G= 10m/s^2

Please help .... atleast tellll me how i can solve it

i can only get to this point

T= 6.28(√L/G)

please help

Thank You

This is more of a physics problem, as 2π·√(L/G) is the approximation formula for the period of a simple pendulum at small angles. (Where L is the length of the string and g is gravitational acceleration.)

Use L and G in the equation:

T = 2π·√( L / G )

T = 2π·√[ (0.5m) / (10m/s²) ]

T = 2π·√( 0.05 s² )

T ≈ 1.4 s
