The outer shells of the atom are the rings around it if that’s what you’re asking
Answer:
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 <u><em>weight is a measurement of the force of gravity pulling (the mass of) an object</em></u>. 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.
