Answer:
360,000 kilometers
Explanation:
Because the moon is the closest to the earth and sorry if it was no help and it wrong but i think its 360,000 kilometers.
Answer:
3
Explanation:
not 100 percent sure but i think so
Biomolecules are organic compounds that are present as essential components of living things. There are four major biomolecules namely lipids, proteins, carbohydrates and nucleic acids. Proteins, lipids and glucose are usually used by organisms as energy sources as well as structural components among other functions in living organisms. Nucleic acids are important components that bring about heredity. In this case the appropriate molecule to be chosen by the long distance learner would be carbohydrate because it stores and may be used as a source of energy.
yes,because with no qualification you can not make the right choice when voting
We have the following assumptions:
The temperature of the surroundings remains constant.
The entire surface area of head emits radiation.
From the problem, we have the given values:
emissivity = 0.95
T2 = 36 degrees C
T1 = 9 degrees C
Solving for the area:
A = πD² + πDh = π(21)² + π(21)(20) = 2709.91 cm² = 0.2710 m²
Using the heat transfer equation for radiation:
q = εAσ(T₂⁴ - T₁⁴)
q = 0.95 (0.2710)(5.67 x 10<span>-8)[(36+273)</span>⁴-(9+273)⁴]
q = 3.9 x 10^9 W
