If T = 2 π √1/g, make g the subject of the formula
A.
(4π l2) / T
B.
(4π2l) / T2
C.
(4π2l2) / T2
D.
(2π√l) / T
Correct Answer: (4π2l) / T2
Explanation
T = 2 π √1/g T/2π = √1/g (T/2π)2 = (√1/g)2 T2/4π2 = 1/g T2 x g = 4π2 x l G = (4π2 x l) / T2
T = 2 π √1/g T/2π = √1/g (T/2π)2 = (√1/g)2 T2/4π2 = 1/g T2 x g = 4π2 x l G = (4π2 x l) / T2THIS WEEK's
