Question

during a high - altitude endurance race where gravity is slightly less than at sea level, how would the performance of material b be affected in terms of runner experience? it would weigh more, increasing runner fatigue. it would weigh less, but its elasticity would remain unchanged. it would become more dense, resulting in greater responsiveness. it would become less dense, resulting in more flexibility for the runner.

Explanation:

Weight is the product of mass and gravitational acceleration ($W = mg$). At high - altitude, gravity ($g$) is less. So the weight of Material B would be less. Elasticity is an inherent property of the material and is not affected by gravity.

Answer:

It would weigh less, but its elasticity would remain unchanged.
