Apollo 17 astronauts eugene cernan and harrison schmitt collected the last samples of moon rocks to bring back to earth in 1972 The astronauts took measurements of the moon rocks using three categories not affected by gravity this is because the earth and moon have different forces of gravity which measurement did they not use? A-Volume
B-Weight
C-Mass
D-Density

The correct answer is B

Explanation:

This question seeks to test the difference between mass and weight.

Mass is a measurement of the amount of matter present in an object. While weight is a measurement of the force of gravity pulling (the mass of) an object. Hence, measuring the weight of the moon rocks in the moon might be a waste since the weight of the object on earth will produce a different value due to the difference in the force of gravity between the earth and the moon.

sry but any answer choices
