I've been told that if you drop a magnet through a coil the induced emf and flux graphs would look like this: I understand that when the bar magnet is in the middle of the coil the emf induced is zero as flux change in top and bottom is in opposite directions but why is effective flux maximum...

But how much gas will flow into the balloons, will the gas stop flowing once the pressure inside the cylinder is 1.85x10^5 Pa?

There might be, as gas takes up the volume of the container. It wasn't mentioned in the question tho.

P1V1=P2V2 (2.5x10^7x4x10^4)/1.85x10^5 , V2 = 5.41x10^6 cm^3 5.41x10^6=4x10^4+7.24x10^3 N N= 741
