Abalance uses small metal weights of known mass to determine the mass of a substance. where would a balance not function correctly?
a. in a vacuum on earth
b. on the moon's surface
c. on the earth's highest mountain
d. in a zero gravity environment

In a zero gravity environment. As gravity fields extend out in the vase expanse of space indefinitely, though scientists use the term where no noticeable effects are seen on matter. When an object is in the weaker part of a gravity field, there is nothing that can determine the weight of the object, as that would require a strong gravitational field. Which means the correct answer is  D I hope it helps you. It definitely would not be in a vacuum on Earth or on the Earth's highest mountain. Like I said though, I hope this helps.
