Question 43

An observer defines three periods of time:

$T_H$ : the time taken for the hour hand of a standard analog clock to make one complete revolution
$T_E$ : the time taken for the Earth to rotate once on its axis
$T_M$ : the time taken for the Moon to orbit the Earth

Which row correctly identifies the shortest period of time and the longest period of time?

A

Shortest: $T_E$ ; Longest: $T_M$

B

Shortest: $T_H$ ; Longest: $T_M$

C

Shortest: $T_H$ ; Longest: $T_E$

D

Shortest: $T_M$ ; Longest: $T_H$
