Answer:
An increase in air temperature because of its compression.
Explanation:
The Gay-Lussac's Law states that a gas pressure is directly proportional to its temperature in an enclosed system to constant volume.
<em>where P: is the gas pressure, T: is the gas temperature and k: is a constant.</em>
Therefore, due to Gay-Lussac's Law, when the plunger is pushed down very rapidly, the pressure of the air increase, which leads to its temperature increase. That is why cotton flashes and burns.

Answer:
Electrons and protons are connected with one another in term of charge and size.
Explanation:
- The size of electron and proton is always same in any atom but they possess opposite charge.
- Electron in any atom carries negative charge where as proton carries the positive charge.
- In any neutral atom the charge between electron and proton is balanced along with the size.
- The nucleus of any atom bounds only proton and neutron but the electron is present revolving around the nucleus.
Answer:
BC and DE
Explanation:
In the given figure, the velocity time graph is shown. We know that the area under v-t curve gives the displacement of the particle.
Area under AB, 
Area under BC, 
Area under CD, 
Area under DE, 
Area under EF, 
So, form above calculations it is clear that, during BC and DE undergo equal displacement. Hence, the correct option is (c) "BC and DE = 4 meters".
