The distance from the thermal energy source affect the amount of thermal energy transfer occurring in a substance in a way that area that the radiation is spread over is four times as large for just the double distance.
Thermal energy that can transfer between substances always does so from one that is warmer to one that is cooler. Conduction, convention, and radiation are the three categories. Distance causes the heat radiation emitted by a source, such the sun, to disperse.
As it moves away from the source, the same quantity of energy is dispersed over a larger and larger sphere every second. For simply the twice distance, the radiation's distribution area is four times as large.
The solar constant (also known as the solar coefficient), abbreviated S, refers to the Sun's intensity on Earth, , in units. This information reveals how much radiation enters a square metre of Earth (or any other planet at a similar distance from the sun).

I think the answer is 2-elements
Answer:
The answer to your question is 177.8 g of NaOH
Explanation:
Balanced chemical reaction
2 Na + 2 H₂O ⇒ 2 NaOH + H₂
Data
Grams of H₂ = ?
Mass of Na = 120 g
Mass of H₂O = 80
Process
1.- Calculate the limiting reactant
Molar mass of Na = 2 x 23 = 46 g
Molar mass of H₂O = 2 x 18 = 36 g
Theoretical proportion Na/H₂O = 46/36 = 1.28
Experimental proportion Na/H₂O = 120/80 = 1.5
As the experimental proportion increases, we conclude that the limiting reactant is the water.
2.- Calculate the mass of hydrogen
Molar mass of NaOH = 2[23 + 16 + 1] = 80 g
36 g of H₂O ------------------ 80 g of NaOH
80 g of H₂O ----------------- x
x = (80 x 80) / 36
x = 6400 / 36
x = 177.8 g of NaOH
Answer:
Carbon monoxide + hydrogen ------> methanol
Explanation:
In writing a chemical equation, the substances which react together to form other substances are known as products and are usually placed on the left side of a the equation, whereas the substances that are formed by the reactants are known as products and are usually written on the right side of the equation. A forward pointing arrow is usually placed between the reactants and and products to show how the reaction proceeds from reactants to formation of products.
From the given equation, methanol is the product formed from the reactants carbon monoxide and hydrogen. Therefore, the equation will be:
carbon monoxide + hydrogen -----> methanol
Answer:
Energy emitted by photon = 45.06 × 10−32 J
Explanation:
Energy of photon is given by E = hf
where
h is the Planck's constant whose value is 6.626×10−34J⋅s
f is the frequency of photon
________________________________________
given that
f = 6.8 x 104 Hz
1 HZ = 1 s^-1
E = 6.626×10−34J⋅s * 6.8 x 10^4 Hz
E = 45.06 × 10−32 J
Thus,
Energy emitted by photon is 45.06 × 10−32 J
