Question

question 8 1 pts a supplier wants to make a profit by buying metal by weight at one altitude and selling it at the same price per pound at another altitude. the supplier should disregard altitude because it makes no difference. buy at a low altitude and sell at a high altitude. buy at a high altitude and sell at a low altitude. each of us weighs a tiny bit less inside the ground floor of a skyscraper than we do on the ground away from the skyscraper. the reason for this is the mass of the building attracts us upward slightly. none of these both of these gravitational field is shielded inside the building.

Explanation:

The weight of an object is related to the gravitational force acting on it. The gravitational force \(F = mg\), where \(m\) is the mass and \(g\) is the gravitational - acceleration. The gravitational acceleration \(g\) decreases with increasing altitude. When buying metal by weight, to make a profit by buying at a lower \(g\) (higher altitude) and selling at a higher \(g\) (lower altitude). For the second part, the mass of the building attracts us upward slightly, reducing the net gravitational pull towards the Earth's center, making us weigh a tiny bit less inside the ground - floor of a skyscraper.

Answer:

Question 8: buy at a high altitude and sell at a low altitude.
Second - question: mass of the building attracts us upward slightly.
