Question 18

A student defines three periods of time:

  • TET_{\text{E}}TE​: the time taken for the Earth to orbit the Sun
  • TRT_{\text{R}}TR​: the time taken for the Earth to rotate once on its axis
  • TMT_{\text{M}}TM​: the time taken for the Moon to orbit the Earth

Which of the following correctly orders these periods of time from shortest to longest?

A

TR<TM<TET_{\text{R}} < T_{\text{M}} < T_{\text{E}}TR​<TM​<TE​

B

TM<TR<TET_{\text{M}} < T_{\text{R}} < T_{\text{E}}TM​<TR​<TE​

C

TR<TE<TMT_{\text{R}} < T_{\text{E}} < T_{\text{M}}TR​<TE​<TM​

D

TE<TM<TRT_{\text{E}} < T_{\text{M}} < T_{\text{R}}TE​<TM​<TR​
