Is RMS Velocity depends upon pressure of gas or not?

Or

In a Young's double slit experiment, the two slits act as coherent sources of waves of equal amplitude $A$ and wavelength $\lambda$. In another experiment with the same arrangement , the two slits are made to act as incoherent sources of waves of same amplitude and wavelength. If the intensity at the middle point of the screen in the first case is $I_1$ and in the second case is $I_2$, then the ratio $\frac{I_1}{I_2}$ is :

The efficiency of a Carnot engine which operates between the two temperatures $T_1=500Kand{T}_2=300K$ is:

The correct order of hydration energy is:

Nuclear binding energy is the energy released during the hypothetical formation of the nucleus by the condensation of individual nucleons. Thus, binding energy per nucleon =$\frac{\text{Total binding energy}}{\text{Number of nucleons}}$ For example, the mass of hydrogen atom is equal to the sum of the masses of a proton and an electron. For other atoms, the atomic mass is less than the sum of the masses of protons, neutrons and electrons present. This difference in mass, termed as mass defect, is a measure of the binding energy of protons and neutrons in the nucleus. The mass-energy relationship postulated by Einstein is expressed as: $\Delta E=\Delta m{c}^2$

Where $\Delta E$ is the energy liberated, $\Delta m$ is the loss of mass, and c is the speed of light.

In the reaction ${}_1^{2}H{+}_1^{3}H{\to }_2^{4}He{+}_0^{1}n$, if binding energies ${}_1^{2}H{,}_1^{3}H\text{and}{}_2^{4}He$ are respectively a, b and c (in MeV), then the energy released in this reaction is:
