The relationship between the period T and the length T of a smile pendulum is T = 2( pi ) ( ( frac{I}{g}) ^{ frac{1}{2} } ). From experiment data of T and I, one can obtain the following graphs, i. T vs.I ii. T vs I2 iii. T2 vs. I iv. T vs ( sqrt{I} ) v. logT vs logI. Which of the following graphs, are linear?
-
A.
all -
B.
only i and ii -
C.
only iii and iv -
D.
iii,iv and v -
E.
none of them
