You wish to start a fire by reflecting sunlight from a mirror onto some paper under a pile of wood which means the best choice of the type of mirror for this operation is a concave one and is denoted as option B.
<h3>What is Concave mirror?</h3>
This type of mirror usually has a reflective surface that is curved inward and away from the light source. They also reflect light inward to one focal point which is done by reflecting all the rays parallel to its axis and converge them at a single point.
For fire to occur, then we need a large concentration of light rays which will help reflect all the sunlight from a mirror onto some paper under a pile of wood thereby causing the fire.
This is therefore the reason why concave mirror was chosen as the most appropriate choice.

<u><em>Answer:</em></u>498.82 cg is equivalent to 4988.2 mg
<u><em>Explanation:</em></u>cg stands form centigrams
mg stands for milligrams
From the standards of conversion, to convert from centi to milli, we multiply the amount ny 10
<u>This means that:</u>
1 centigram = 10 milligram
To convert 498.82 cg to mg, all we have to do is <u>cross multiplication</u> as follows:
1 cg ..................> 10 mg
498.82 cg .........> ?? mg
498.82 cg = </span>
<span> = 4988.2 mg

Answer:
See the answer below
Explanation:
The temperature stops rising when water begins to boil because the heat which causes the rise in temperature is now diverted into changing the phase of the boiling water.
The conversion of substances from one state of matter to another requires energy. Hence, instead of causing a rise in the temperature of the boiling water, the heat is used to convert the liquid water into vapor. The heat thus becomes what is known as the latent heat of vaporization.
