AFrom 9.78 m/s^2 to 9.83 m/s^2
BFrom 9.00 m/s^2 to 9.80 m/s^2
CFrom 1.67 m/s^2 to 9.80 m/s^2
DFrom 9.80 m/s^2 to 10.8 m/s^2
Answer & Solution
Correct answer: A. From 9.78 m/s^2 to 9.83 m/s^2
1. The acceleration due to gravity depends on latitude, altitude, underlying geology and local topography.
2. Because of that it varies from 9.78 m/s^2 to 9.83 m/s^2 across the Earth.
3. The average value of 9.80 m/s^2 sits inside that narrow band and is used unless stated otherwise.
4. A value of 1.67 m/s^2 belongs to the Moon and lies far outside the Earth range.
