400 BTU of wasted heat energy is present in the form of electricity.
<h3><u>Energy sources and usage</u></h3>
- Potential energy sources include fossil fuels like coal, oil, and natural gas. Other energy sources include hydro, solar, and wind.
- Additionally, nuclear energy may also come from radioactive materials.But energy will constantly lose its strength.
- Industries would never be able to derive a full amount of energy from their sources.We can only obtain 60% of the energy in ideal situations, such as the Carnot engine. This is if the case is ideal. Actually, we receive considerably less than this for roughly 40%.
So, when efficiency is 60%, energy is used 60% of the time and lost 40% of the time. Thus, according to question, the energy that is wasted is:
1000 BTUx (40/100) = 400 BTU

you are given the number of moles, from the given formula you can get the molar mass which is 12.00g/mol + 16 g/mol =28 g/mol. using the formula n=m/Mr rearrange the formula and make m subject, you thn have m=nMr therefore 7.60x 1021 mol x 28g/mol= m
m = 217268.8 g, you will notice that mol cancel out each other leaving you with g.
now convert g to litres
1 litre is equal to 1000 grams therefore
217268.8g x 1l/1000g = 217,269 litres
Answer:
The sun has nearly 99.98% of the mass of the Solar System, which classifies it as having the greatest amount of gravity.
Explanation:
Answer:
A
Explanation:
The total number of each type of atom always stay the same.
Answer: Infrasound because sound waves travel easily through water to accessible buoys.
Explanation: its installation: underwater microphones hung from buoys near a volcano. how it works: senses low-frequency sound waves near a volcano. Since in its installation it specifies that it has UNDERWATER microphones and the question asks in predicting an eruption from an UNDERSEA volcano, that makes perfect sense.
