Of these options the one which best answers the question is 'Use whatever professionals claim to use.'
It is not that professional recommendations should not be consired or valued. The reason you should not just use whatever professionals claim to use is that their needs, as professionals, may be very different from your own. In order to know whether your own needs will be met you need to know what those needs are and whether the product meets those needs. All of the other options given would help you to figure this out, but the testimony of professionals would not.

How does the scientific process generally begin?

Murljashka [212]

There are several approaches. The most favourable one (in my opinion) is this one:
1. Asking a question
2. Doing a research (how to answer this question)
3. Creating a hypothesis (NOT a thesis!)
4. Experimenting (to prove the hypothesis)
5. Analysing results from the experiment
6. Writing a thesis

At high noon, the sun delivers 1150 w to each square meter of a blacktop road. if the hot asphalt loses energy only by radiation

Pie

Stephen`s Law:
P = (Sigma) · A · e · T^4
P in = P out
e = 1 for blacktop;
1150 W = (Sigma) · T^4
(Sigma) = 5.669 · 10 ^(-8) W/m²K^4
T^4 = 1150 : ( 5.669 · 10^(-8) )
T^4 = 202.875 · 10^8
$T = \sqrt[4]{202.857 * 10 ^{8} }$
T = 3.774 · 10² = 377.4 K
Answer: Equilibrium temperature is 377.4 K.
