Question

A supplier wants to make a profit by buying metal by weight at one altitude and selling it at the same price per pound weight at another altitude. The supplier should
a. buy at high altitude and sell at low altitude
b. buy at low altitude and sell at high altitude
c. disregard altitude because it makes no difference

Answer 1

The correct option is C.

In physics, the gravitational law makes us to understand that gravity change with altitude. The higher the altitude, the more the gravity one will experiences. Change in altitude also produce change in weight but all these changes are not really significant. Therefore, there will be no significant difference between weighing metals at different altitude, this is because the effect of gravity on them will be the same.
