Nov 04 Q6 part c:

Change in flux linkage = NA [ B(initial) - B(final) ] Determine B from the graph for the given displacement

nov 02 Q7 Part b

Use SHM knowledge and apply x= x(max) Sin (wt) Where x is displacement from mean position i.e amplitude

June 05 Q2 part b ii

Using

P=1/3 p <c^2)

deduce to (be replacing chota p( density) by Nm/V)

PV = 1/3 Nm <c^2>

Replace this equation in the other equation given i.e PV= NkT

From there make one side of equation equal to 1/2 m <c^2> which can be done by dividing both side by 2... and 1/2 m <c^2> is kinetic energy of gas, so thats ur answer -_-

And you are welcome 'in advance'
