Two infinite straight wires run through an "infinite" solenoid a distance d = 2cm from the center of the solenoid. the wires carry a current of iwire = 5a in the direction drawn. the solenoid carries a current of isol = 1.5a in the direction drawn. the solenoid is wound using 500 turns of wire on a 13cm tube. (a)compute the magnetic field of the solenoid at point p, b~ sol. (b)compute the magnetic field of wire 1 at point p, b~ wire1. (c)compute the magnetic field of wire 2 at point p, b~ wire2. (d)compute the total magnetic field at point p.

Agas contained within a piston-cylinder assembly e end nation about same energy states, 1 and 2, where pi 10 bar, v undergoes two processes, a and b, between the sam 0.1 m3, ui-400 kj and p2 1 bar, v2 1.0 m2, u2 200 kj: process a: process from 1 to 2 during which the pressure- volume relation is pv constant process b: constant-volume process from state 1 to a pressure of 2 bar, followed by a linear pressure-volume process to +20 0 state 2 kinetic and potential energy effects can be ignored. for each of the processes a and b, (a) sketch the process on p-v coordinates, (b) evaluate the work, in kj, and (c) evaluate process the heat transfer, in kj
