The length of a pendulum changes by thermal expansion. If the length increases by 0.1%, what would be the change in the period?
A) increase by $ \sqrt{1.001} $
B) increase by 0.1%
C) decrease by 0.1%
D) decrease by 0.99

Question

Quizplus · Accepted Answer

The period of a pendulum is proportional to the square root of its length. If the length increases by 0.1%, the period increases by $ \sqrt{1.001} $.

The Length of a Pendulum Changes by Thermal Expansion 1.001 \sqrt{1.001} 1.001​

The Length of a Pendulum Changes by Thermal Expansion $\sqrt{1.001}$
