Answer:
It is a little bit trivial:
As we know:
Energy sink: is anything that uses energy.
Energy source: is anything that produces energy.
How the caol deposits can be energy sinks? well, you want to extract the coal from those deposits, and to do it, you need to "use energy" (the type of energy can depend on the extraction method, for example, if you use a pickaxe to extract the coal, you are using mechanical energy)
These coals are potential energy sources because coal is an energy source, potential means that, given some circumstances, something can transform into other things.
So potential energy source in this situation means that those coal deposits can be potential energy when we extract the coal and use it as an energy source.
Answer:
<h2><em><u>80</u></em><em><u>%</u></em>.</h2>
Step-by-step explanation:
<em><u>Since</u></em><em><u>,</u></em>
Any number if divided by hundred then that no. is known as a <em><u>percentage</u></em>.
<em><u>Here</u></em><em><u>,</u></em>
<em><u>80</u></em><em><u> </u></em><em><u>is</u></em><em><u> </u></em><em><u>divided</u></em><em><u> </u></em><em><u>by</u></em><em><u> </u></em><em><u>100</u></em><em><u> </u></em><em><u>i</u></em><em><u>. </u></em><em><u>e</u></em><em><u>.</u></em>
80 / 100
= <em><u>80% (Ans)</u></em>
Okay. So when it comes to combining like terms, they should have the same variable and power. They dont have to be the exact same number, but they should at least have the same terms. In the expression 40 + 15e + 10e, 15e and 10e both have like terms, because they have the same variable. 15e + 10e is 25e. 40 has no like term, so that is left alone. The expression simplified is 40 + 25e.
1)the letter x is two times the product two Hope fully this is hopeful and you can do the same on the rest by just changing the number
