The correct answer is B
The gas having lowest boiling point i.e., highly volatile will be distilled out first and the gas having highest boiling point i.e., least volatile will be distilled out at the last. So, the correct order of gases distilling out is neon, nitrogen, oxygen, krypton.

The correct answer is D
Current carrying wire produces magnetic field, but direction of magnetic field on the given points X and Y are different.
This is found by right hand thumb rule. So magnetic compasses on X and Yexperience magnetic force of same magnitude but in opposite directions. Hence, the needles will deflect in opposite directions.

The correct answer is B
Coil P is moved with a uniform speed towards Q while R is static. Due to the current in P, magnetic field is from right to left. When P is moved towards Q, magnetic lines passing through Q (from right to left) will increase, i.e., magnetic flux passing through Q will increase. Therefore, current will be induced in Q. The induced current will have such a direction that it gives a magnetic field opposite to that passing through Q due to current in P. Thus, anticlockwise current will be induced in coil Q, opposite to the direction of current in coil P.
