Answer:

Nuclear Fuel is derived from the splitting of uranium atoms also known as fission. Uranium is mined and undergoes refining and enrichment and put through a nuclear reactor. Then it is put into fuel rods and grouped to form fuel assemblies. It is finally stored in the reactors core.

Wind gets is original energy from the sun. The sun heats the surface of the earth and the air above it warms and rises upwards into the atmosphere. Wind is used to power water pumps and was used to move boats along rivers.

<u><em>Question 1: </em></u>

The natural gas starts by piping natural gas underground to power plants, then the power plants burn the natural gas to boil water that becomes steam. The steam spins the blades of a turbine that is connected to a generator, then the generator spins the magnets which generate the electricity.

<u><em>Part B:</em></u>

Natural gas: The original form of natural gas is a fossil energy source. Natural gas plants use a gas turbine; natural gas is added, along with a stream of air, which combusts and expands through this turbine causing a generator to spin a magnet, making electricity.

Coal: The original form of coal is peat. Coal-fired plants produce electricity by burning coal in a boiler to produce steam. The steam produced, under tremendous pressure, flows into a turbine, which spins a generator to create electricity. The steam is then cooled, condensed back into the water, and returned to the boiler to restart the process.

Nuclear fuel: <em>Sorry couldn't do this one, it's 4 am and my brain just isn't working w me too well.</em>

Hydropower: The original form of hydropower is water. The hydropower plants water flows through a pipe, or penstock, then pushes against and turns blades in a turbine to spin a generator to produce electricity

Wind: <em>Sorry couldn't do this one either.</em>

I'm sorry I didn't do two of them but I really hope this helps.

Dna is approximately 2.5 nm in length. of an average man is 5 ft 10 in. tall, how many dna molecules could be stacked to extend
Angelina_Jolie [31]
To determine the number of dna molecules that can be stacked as requested in this item, we convert the given measurements in a single unit. For simplicity, we convert all the lengths to meters.

Length of DNA molecule = (2.5 nm)(1 x 10^-9 m/1 nm) = 2.5 x 10^-9 nm

Height of a person = (5 ft 10 in)(12 inches/ 1ft)(2.54 cm/1 in)(1 x 10^-2 m/ 1 cm)
               = 1.778 m

Then, divide the height of the person by the length of a single DNA molecule.

       n = 1.778 m / (2.5 x 10^-9)
       n = 7.112 x 10^8

Hence, the number of DNA would be 7.112 x 10^9.
