select the phrase that has a connection with the vocabulary word pendulum. a writing instrument a racing motorcycle a grandfather clock

Answer

Brief Explanations:

A pendulum is a weight suspended from a pivot so it can swing freely, and a grandfather clock uses a pendulum to keep time. A writing instrument (like a pen) and a racing motorcycle have no connection to a pendulum. So the phrase connected to "pendulum" is "a grandfather clock".

Answer:

a grandfather clock
