Period of Pendulum

If the pendulum is allowed to swing through a small angle, the period T is given by the formula:
                  T=2π (L/g)
Where L is the length of the pendulum.
Let there are two pendulums.
The length of the first pendulum is four times greater than the length of the second pendulum (L1 = 4 L2)
Compare periods of these pendulums.
a) The period of the first pendulum is four times greater than the period of the second pendulum
(T1 = 4 T2);
b) The period of the first pendulum is two times greater than the period of the second pendulum
(T1 = 2 T2);
c) The period of the second pendulum is four times greater than the period of the first pendulum
(T2 = 4 T1);
d) The period of the second pendulum is two times greater than the period of the first pendulum
(T2 = 2 T1);
e) The periods of the pendulums are equal to each other (T1 = T2).

Distance

If you wanted to make a distance that is 3 m 4 cm in length 10 times longer, how long will it be?
a) 33 m 4 cm, b) 30 m 4 cm, c) 3 m 40 cm, d) 34 m 0 cm, e) 30.4 m.  

Feet, Inches

If you wanted to make a table that is 3 feet 4 inches in length 10 times longer, how long will it be?
a) 33 feet 4 inches, b) 30 feet 4 inches, c) 3 feet 40 inches, d) 34 feet 0 inches, e) 30.4 feet.
