Copper can be drawn into thin wires. how many meters of 34-gauge wire (diameter 6. in) can be produced from the copper in 5.01 lb of covellite, an ore of copper that is 66% copper by mass? (hint: treat the wire as a cylinder: v of cylinder ; d of copper 8.95 g/cm3.)

Covellite ore contains 66% copper by mass thus, in 5.01 lb of covellit, mass of copper will be :

Converting mass into grams,

1 lb=453.592 g

Thus, 5.01 lb=2272.498 g

The density of copper is , calculate volume as follows:

Comparing this volume of cylinder because shape of wire is cylindrical.

Since, 34 gauge=0.00630 inch

Convert inch into cm,

1 inch=2.54 cm

Thus,

0.00630 inch=0.016002 cm

The diameter of wire is 0.016002 cm, calculate radius as follows:

Rearranging equation for volume and putting the values,

1 cm=0.01 m thus,

Thus, the length of wire is .

hurricanes form when warm, moist air from the ocean surface quickly rises into the atmosphere and forms storm clouds and rain. when the clouds are formed, heat is released which warms the cool air in the upper regions of the atmosphere so that the cycle can continue. which two phases of the water cycle are repeated in this process?
