The internal combustion engine has been criticized for ages for its negative effects on human health as well as the deterioration that it has caused to the environment with the release of Carbon Dioxide (CO2). However, to settle the skeptics, studies have been conducted to prove the environmental benefits of the internal combustion engine.
According to an article written by Dr. Dwight R. Lee, an Economist at the University of Georgia, livestock is responsible for 18% of the greenhouse gases that cause global warming, a far higher statistic than the contribution made by automobiles and aircrafts. The internal combustion engine began replacing horses as a source of power in the early 1900s, which started replacing the outputs from animals with exhaust from tailpipes.
The electric flux is changed only if we change the charge.
<h3>What is the expression of electric flux?</h3>
- As per gauss law, total electric flux link through a surface is equal to (1/ε0) × charge.
- Mathematically, electric flux = q/ε0
- q = total charge enclosed by the gaussian surface
- Here the electric flux is directly proportional to the charge, so on changing charge, the electric flux changes.
Thus, we can conclude that the electric flux is changed only if we change the charge.

Answer:
Approximately 6.8 x 10⁻¹⁵
Explanation:
To be able to get this fraction, there are some things we need to know.
1. The radius of nucleus = 1.0 x 10⁻¹³ cm
2. The radius of hydrogen atom = 52.9 pm
3. Volume of sphere = V1/V2 = (R1/R2)^3
4. 1 picometer (pm) = 10^-10 cm

Stars and planets because of there gravitational pull but planets are the most likely out of all of them because planets are closer together than stars so they pull each other in
The amount of heat energy that must still be removed by the cooling system is 1300 kJ.
<h3>Conservation energy</h3>
The total energy before and after a transformation must be equal.
Based on this principle, the heat energy that must still be removed by the cooling system is calculated as follows;
Input heat energy = out put heat energy
E = h + w
2000 kJ = h + 700 kJ
1300 kJ = h
Thus, the amount of heat energy that must still be removed by the cooling system is 1300 kJ.
