with the same generator, so the only factor for producing
the slectric field is only the speed. The faster the rotational speed of the
generator the greater it produce electric field. So the sequence is 3000 rpm
< 3200 rpm < 3400 rpm < 3600 rpm
Answer:
Gay-Lussac’s law, because as the pressure increases, the temperature increases
Explanation:
First of all, we can notice that the volume of the tank is fixed: this means that the volume of the air inside is also fixed.
This means that in this situation we can apply Gay-Lussac's law, which states that:
"for a gas kept at constant volume, the pressure of the gas is proportional to the absolute temperature of the gas".
Mathematically:
![p\propto T](https://tex.z-dn.net/?f=p%5Cpropto%20T)
where p is the pressure in Pascal and T is the temperature in Kelvin.
In this case, the tank is filled with air: this means that the pressure of the gas inside the tank increases. And therefore, according to Gay-Lussac's law, the temperature will increase proportionally, and this explains why the tank gets hot.

Answer:![v_1=28.4 cm/s](https://tex.z-dn.net/?f=v_1%3D28.4%20cm%2Fs)
Explanation:
Given
mass of marble ![m_1=27 gm](https://tex.z-dn.net/?f=m_1%3D27%20gm)
velocity of marble ![u_1=56.8 cm/s \approx 0.568 m/s](https://tex.z-dn.net/?f=u_1%3D56.8%20cm%2Fs%20%5Capprox%200.568%20m%2Fs)
mass of second marble ![m_2=13.5 gm](https://tex.z-dn.net/?f=m_2%3D13.5%20gm)
Velocity of second marble ![u_2=14.2 cm/s \approx 0.142 m/s](https://tex.z-dn.net/?f=u_2%3D14.2%20cm%2Fs%20%5Capprox%200.142%20m%2Fs)
After collision 13.5 gm marble moves to the right at i.e. ![v_2=71 cm/s](https://tex.z-dn.net/?f=v_2%3D71%20cm%2Fs)
Conserving momentum
![m_1u_1+m_2u_2=m_1v_1+m_2v_2](https://tex.z-dn.net/?f=m_1u_1%2Bm_2u_2%3Dm_1v_1%2Bm_2v_2)
![27\times 56.8+13.5\times 14.2=27\times v_1+13.5\times 71](https://tex.z-dn.net/?f=27%5Ctimes%2056.8%2B13.5%5Ctimes%2014.2%3D27%5Ctimes%20v_1%2B13.5%5Ctimes%2071)
![1533.6+191.7=27\cdot v_1+958.5](https://tex.z-dn.net/?f=1533.6%2B191.7%3D27%5Ccdot%20v_1%2B958.5)
![27\cdot v_1=766.8](https://tex.z-dn.net/?f=27%5Ccdot%20v_1%3D766.8)
![v_1=\frac{766.8}{27}=28.4 cm/s](https://tex.z-dn.net/?f=v_1%3D%5Cfrac%7B766.8%7D%7B27%7D%3D28.4%20cm%2Fs)
