"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.

object 2 because all the other ones are wrong

this is an example of "committed" time.

committed time, as contracted time, takes need over essential and available time since it is seen as profitable work. it alludes to the time allotted to keep up a home and family. at the point when a man is commuting using committed time this individual may feel that the drive is an obligation to family, for example, strolling youngsters to class or driving a mate to work. contracted and committed time clients may feel that their commute could really compare to the commute of important or leisure time clients on the grounds that their commute is profitable work. in this manner, they might be more disposed to pick a mechanized method of movement.
