2. A pendulum is built by attaching a 1-kg mass to the end of a 120 cm-long string. The mass is
displaced 30 cm from the center and released. It begins to swing back and forth, taking 2 seconds
to travel from one side to the other and back again. Which of the following describes the period
of this pendulum?
F. 1 kg
G. 2 s
H. 30 cm
J. 120 cm

Respuesta :

octopods

Answer:

G. 2s

Explanation:

The period of a pendulum is measured in time. Out of the four options, only one of them is measured in time so it must be G.

A period of a pendulum is how long it takes to swing back to it's original position, and this time (2 seconds) is given in the question as well
