Alice steps on a scale on Earth that is calibrated to measure one's weight in Newtons at the surface of the Earth, and she finds that she weighs 500 N. Which of the following is true?
A. If Alice were to step on an identical scale on the surface of the Moon, then the scale would read less than 500N, but Alice's mass would be the same on the Moon as it was on Earth.
B. On the Moon, both Alice's weight and her mass are different than on Earth.
C. If Alice were to step on an identical scale on the surface of the Moon, then the scale would read more than 500N, but Alice's mass would be the same on the Moon as it was on Earth.
D. If Alice were to step on an identical scale on the surface of the Moon, then the scale would still read 500N.
E. On the moon, Alice's weight is the same as her weight on Earth, but her mass is smaller
