The length (L) of a simple pendulum is directly proportional to the square of the time period (T). Which type of graph can best describe this relationship?
A. hyperbolic B. inverse C. linear with negative slope
D. linear with positive slope E. quadrat
the answer is E. quadratic proof (L) of a simple pendulum is directly proportional to the square of the time period (T), means  L= kT^2, k is the coefficient of proportionality
