Question

a balance 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

Explanation:

A balance measures mass by comparing gravitational forces on both pans, requiring a gravitational field. All options (A, B, C) have gravity, so the balance functions correctly in each.

Answer:

None of the provided options (A, B, C) are correct as the balance works in gravitational fields.
