A 100-kilogram astronaut travels to the moon and steps onto a bathroom scale. The scale reads “16.7 kilograms.” Which statement best describes the reason for this observation? [1 point]
A: The scale was designed to use the person’s mass on Earth to tell him his weight.
B: The scale was designed to use the person’s weight on Earth to tell him his mass
C: The scale was designed to use the person’s mass on the moon to tell him his weight
D: The scale was designed to use the person’s weight on the moon to tell him his mass.
I GOT A 100% here are the answers:
1.weight
2.Yes, they would still be balanced because their masses would not change.
3.The scale was designed to use the person’s weight on Earth to tell him his mass.
4.m=D*V (the dot is a times symbol
5.Density
thanks willy wonka i got a 100.
willy is right
thx

The correct answer is C: The scale was designed to use the person's mass on the moon to tell him his weight.
To understand why, we need to consider the difference between weight and mass. Weight is the force of gravity acting on an object, while mass is the amount of matter in an object. On Earth, the acceleration due to gravity is about 9.8 m/s^2, which means that a 100-kilogram astronaut would weigh approximately 980 Newtons.
However, the moon has a weaker gravitational field compared to Earth. The acceleration due to gravity on the moon is only about 1/6th of that on Earth, or around 1.6 m/s^2. Therefore, when the astronaut steps onto a bathroom scale on the moon, the scale measures the force of gravity acting on the astronaut's mass on the moon, rather than his actual weight. Since the gravitational force is much weaker on the moon, the scale reads a much lower value. In this case, the scale reads "16.7 kilograms."
It's important to note that while the scale is calibrated to measure mass, it still displays the reading in kilograms, which can be misleading. It would be more accurate to say the scale displays the "apparent weight" on the moon, as opposed to the true weight on Earth.
first, consider -- how many scales manufacturers do you think ever even consider the moon when they make their scales?
So now think about the remaining two choices. What do scales tell you?
