Answer:

Bohr.

Explanation:

In 1913, N.Bohr proposed an atomic model for atom. He proposed that in an atom there is a central nucleus and electrons move around this center in a fixed path known as shell.

The shells or path have a fixed size and energy. The electrons do not lose energy during this movement.

There is possibility of energy change (emit or absorb) in an electron if they move from one shell to another.

Explain why uranium must be enriched to be used in a nuclear power plant.
galben [10]

Answer:

The nuclear fuel used in a nuclear reactor needs to have a higher concentration of the U 235 isotope than that which exists in natural uranium ore. U235 when concentrated (or "enriched") is fissionable in light-water reactors (the most common reactor design in the USA).

In large generators in power plants, ___________ rotate inside a coil of wire to produce an electric current
lapo4ka [179]
<h3><u>Answer;</u></h3>

Magnets

In large generators in power plants, <u>magnets</u> rotate inside a coil of wire to produce an electric current.

<h3><u>Explanation;</u></h3>
  • Generators are devices that use electromagnetic induction to convert mechanical energy to electrical energy.
  • In power plants, large wheel known as turbine that rotates when pushed by steam,wind, or water and provides mechanical energy to a generator.
  • <u><em>Generators are used in power plants and have very large quantities of copper wire spinning around inside very large magnets, at very high speeds. A turbine spins the shaft that runs the generator. Eventually, electric current is generated.</em></u>

timurjin [86]
In a closed system, heat should be conserved which means that the heat produced in the calorimeter is equal to the heat released by the combustion reaction. We calculate as follows:

Heat of the combustion reaction = mC(T2-T1)
                                                          = 1 (1.50) (41-21)
                                                          = 30 kJ
