Okay. Ill remember that

I don't know XD

I forgot to add the n. How did we get ## - \Delta U = n C_v (T_2-T_1) ## ? Can you show me step by step?

How come ##adiabatic \,work = C_v(T_2 -T_1)##

Thanks. I'll try that

Homework Statement A uniform spherical charge density of radius R is centred at origin O. A spherical cavity of radius r and centre P is made. OP = D = R-r. If the electric field inside the cavity at position r is E(r), the correct statement is: 1)E is uniform, its magnitude is independent of r...

K. I got it. Thanks

Is it possible for efficiency of R to be more than the backwards running efficiency of I for any engines I and R? Because in that case, net heat would flow from the sink to the source ( I think) which violates the second law of thermodynamics even though Carnot's theorem implies that R should be...

The engines I and R in the second case are not the same engines I and R in the first case. My bad.

Homework Statement Carnot theorem states that no engine working between two temperatures T1 of source and T2 of sink can have a greater efficiency than that of the Carnot engine. Second law of thermodynamics:it is impossible for a self acting machine to transfer heat from a body at a higher...

The source frequency is 50 hz

There was still no voltage across the secondary

That didnt work either. Besides, the project is to make a rod transformer. Maybe i should just make a new one :)
