(a) If gold were sold by weight, would you rather buy it in Denver or in Death Valley? (b) If it were sold by mass, in which of the two locations would you prefer to buy it? Why?

(a)

To determine
The weight of gold.

Explanation

The weight of the gold at a location is equal to the product of its mass and acceleration due to gravity at the location.

The formula to calculate the weight of the gold is,

W=mg

Here,

m is the mass of gold

g is the acceleration due to gravity

The greater the value of the acceleration due to gravity, the greater the weight of gold at that particular location.

The formula to calculate acceleration due to gravity is,

g=Gme(re+h)2

(b)

To determine
The mass of gold.
