The order of magnitude of the given physical quantities would be B < E < D < C
In positional notation, significant figures refer to the digits in a number that is trustworthy and required to denote the amount of something, also known as the significant digits, precision, or resolution.
Here, the order of magnitude of the following physical quantities is as follows
B.The mass of the Moon’s atmosphere: 25,000 kg ⇒ 10 ⁴
C.The mass of Earth: 5.97×10²⁴ kg ⇒ 10²⁴
D.The mass of the Moon is 7.34×10²² kg⇒ 10²²
E.The Earth-Moon distance (semi-major axis): 3.84×108 m ⇒ 10⁸
Thus, the order of magnitude of the given physical quantities would be B < E < D < C
