<u>Answer: </u>
<em>Considering the II law of thermodynamics</em>
<em>From the figure</em>
<em>Out put of energy: </em>
Heat supplied from the source/ reservoir (Q₁) - Heat rejected to the surroundings from the system (Q) = Q₁ - Q₂. Also known as Net work done on the system.
<em>Input of energy: </em>
Amount of heat energy supplied to the system from the source (Q₁ ).
Efficiency (H.E) = η = Output÷ Input
η = (Q₁ - Q₂) ÷ Q₁
OR η = Wnet ÷ Q₁ ; since Wnet = (Q₁ - Q₂)
Answer:
343/440
Explanation:
Recall that v=d/t
Now, this is the same thing.
Frequency is 1/T and wavelength is the distance travelled in one period.
So Vs=f*λ
(the greek letter is used as the symbol of wavelength; it's arbitrary)
For the most part aesthetics but you could argue they reduce air turbulence in some cases which would lead to better gas mileage. On sports cars however the goal is usually down force which is not wanted on economy cars as it can actually worsen gas mileage.
I hope that answered your question.
Answer:
The Wednesday test launch stored more potential energy, and launched the spacecraft at a faster speed because the stronger magnetic field closer to the magnet resulted in a greater increase in potential energy.
Explanation:
Answer:
Eating food produce locally makes it where big trucks don't have to bring it to the restaurant
Explanation:
When the big trucks drive it they release pollutants into the air so therefore when you get stuff produced locally you don't have the big trucks polluting the air. So therefore it is better for the environment.
