The existence of atmosphere increases the average planetary temperature by more than 15°C, due to the greenhouse effect of some atmospheric compounds. The most important of them are water vapour (H2O), ozone (O3), carbon dioxide (CO2), and methane (CH4).
Answer:
Explanation:
First we must find the real power that is dissipating for each of the two cases, this is achieved by multiplying the nominal power by the efficiency
P=Poη
P=power
Po=nominal power
η=efficiency
POWER NUMBER 1
P1=400*0.89=356W
POWER NUMBER 2
P2=400*0.94=376W
then we find the power change by subtracting both results
ΔP=P2-P1=376-356=20W
always ensure that the efficiency in any system is maximized, because it is always required that the amount of energy delivered by the system is maximum with the same input power.
The answer to the first is two arrows.
The second picture, normal force goes up.
Since nuclear fusion in the sun creates energy from matter, Einstein's formula E=mc² states that matter and energy are equal.
To find the answer, we have to know more about the nuclear fusion.
<h3>What is
nuclear fusion?</h3>
- We are aware that the sun can achieve nuclear fusion by the fusion of hydrogen atoms.
- These atoms need to get closer to one another in order to fuse.
- Since both protons inside each nucleus are positively charged, they attempt to repel one another as they get closer to one another.
- If this issue cannot be solved, nuclear fusion in the sun cannot occur.
Thus, we can conclude that, since nuclear fusion in the sun creates energy from matter, Einstein's formula E=mc² states that matter and energy are equal.
