Figure shows two processes A and B on a system. Let ΔQ1 and ΔQ2 be the heat given to the system in processes A and B respectively. Then
1.   ΔQ1  ΔQ2
2.   ΔQ1 = ΔQ2 
3.   ΔQ1  ΔQ2
4.   ΔQ1 ≤ ΔQ2

Sir plzzzz make a video solution upon these two question :-

1)Two persons A and B are moving in opposite directions with same speed V on a horizontal road. An aeroplane is flying horizontally in the sky at constant velocity of magnitude V to A. the plane appears to move perpendicular to the road and to B the plane appears to move at 45° to the road. Find V in terms of V.

2)Two persons A and B running on a track in the same direction observe a car. A says that the car is moving in cast direction and B says the car is moving in north direction. They contradict the direction but say that magnitude is same. If the speed of B is double that of the speed of A. then the true direction of the car will be:
