Copper has a density of 8.96 g/cm3. If a thin sheet of copper measures 5.5 cm by 5.5 cm and has a mass of 12.96 g, what is its t
balandron [24]

Thickness of cooper sheet is 0.048 cm (Approx.)

Given that;

Density of copper = 8.96 g/cm³

Measures of copper sheet = 5.5 cm × 5.5 cm

Mass of of copper sheet = 12.96 gram

Find:

Thickness of cooper sheet

Computation:

Volume = Mass / Density

Volume of cooper = 12.96 / 8.96

Volume of cooper = 1.4464

Volume of cooper = 1.45 cm³ (Approx.)

Volume of cooper sheet = 5.5 cm × 5.5 cm x Thickness

5.5 cm × 5.5 cm x Thickness = 1.45

Thickness of cooper sheet = 0.04793

Thickness of cooper sheet = 0.048 cm (Approx.)

Which fossil fuel has the least amount of carbon dioxide released in the air each year
Natali5045456 [20]

The correct answer is - natural gas.

The natural gas is the fossil fuel that releases the least amount of carbon dioxide in the atmosphere. It actually releases very little to none. The reason for that is that the natural gas is a fossil fuel which has the methane as its main ingredient. Even when used, it is not causing some serious pollution, instead the pollution comes from not well managed infrastructure and movement from one place to another of the natural gas. The biggest problem, pollution wise, comes from the leaking of the natural gas, when methane is released into the atmosphere.
