"Two simple pendulums, A and B, are each 3.0 m long, and the period of pendulum A is T. Pendulum A is twice as heavy as pendulum B. What is the period of pendulum B?"

T

Explanation:

The pendulum of a simple pendulum is given by

where T is the period, l is the length of the pendulum and g is the acceleration due to gravity.

It is seen that this equation does not involve the mass or weight of the pendulum. Thus, the two pendulums will have the same period as long as they are of the same length.

explanation:

c. 7/3

step-by-step explanation:

a rational number is like pi- it is a repeating decimal.

a. is -1.8

b. 2.236068

c. 2.3333333333333333333

d.   is 3

i hope that ! =)
