What power source uses the earths internal heat
nlexa [21]

Answer:

Geothermal power comes from Earth's internal heat

Explanation:

The description applied to power sources tends to match the names applied to the source of energy. Sometimes Latin, or other word derivations are used.

For example, "hydro-" refers to water, so it is no surprise that hydroelectric power comes from the movement of water. Of course, "nuclear" refers to the nuclei of the atoms that are split to release energy in a nuclear power plant. Similarly, "geo-" refers to Earth, and "thermal" refers to heat, so "geothermal" energy is the name given to energy derived from Earth's heat.

Answer: The ratio of carbon to bromine atoms  in the molecule is 3:1

Explanation:

Compound is a pure substance which is made from atoms of different elements combined together in a fixed ratio by mass. It can be decomposed into simpler constituents using chemical reactions.

Chemical formula shows the elements in a compound and the relative proportions of those elements.

The chemical formula given for the compound is C_3H_6BrCl which means the ratio of carbon to bromine atoms is 3: 1.

Thus the ratio of carbon to bromine atoms  in the molecule is 3:1

The direction of electrical force is based on the fact that like charges will___each other.
NeTakaya

Answer:

repel

Explanation:

When it comes to electrical forces, "opposites charges attract" while "like charges repel."

There are primarily two types of charges: positive charge and negative charge. The forces they exert upon each other will depend on their charges. The<u> positive charge has an </u><em><u>attractive force</u></em><u> to a negative charge.</u> On the contrary,<u> it has a</u><em><u> repulsive force</u></em><u> to the same positive charge</u>. Thus, it will repel each other.

So this means that <em>opposite charges will draw closer together</em> while<em> like charges will move apart from each other.</em>
