Asteady current i flows through a wire of radius a. the current density in the wire varies with r as j = kr, where k is a constant and r is the distance from the axis of the wire. find expressions for the magnitudes of the magnetic field inside and outside the wire as a function of r. (hint: find the current through an ampèrian loop of radius r using ithru = j · da. use the following as necessary: μ0, i, a and r. do not substitute numerical values; use variables only.)a. b inside=? b. b outside=?

Acylinder with a movable piston contains 11.7 moles of a monatomic ideal gas at a pressure of 1.32×10^5 pa. the gas is initially at a temperature of 300 k. an electric heater adds 43200 j of energy into the gas while the piston moves in such a way that the pressure remains constant. cp=20.79 j k^−1 mol^−1 for a monatomic ideal gas, and that the number of gas molecules is equal to avogadro's number (6.022×10^23) times the number of moles of the gas. (a) what is the temperature of the gas after the energy is added? (b) what is the change in volume of the gas? (c) how much work is done by the gas during this process?
