An electrophorus is charged (as in electrostatics ii). it briefly touches one terminal of a capacitor so that a positive charge, +q, is put on the plate of the capacitor that is connected to the terminal. after the electrophorus is removed, we have; +q)i any changes take place at other plate (on the right of the diagram)? if so, draw the charge on the following diagram and explain why it appears. your explanation must include reasons for the sign and size of any charge that appears and say how these electrostatic charges +q)i nothing happens to the other plate then explain why not.

Na food processing facility, a spherical container of inner radius r1 5 40 cm, outer radius r2 5 41 cm, and ther- mal conductivity k 5 1.5 w/m · k is used to store hot water and to keep it at 100°c at all times. to accomplish this, the outer surface of the container is wrapped with a 800-w electric strip heater and then insulated. the temperature of the inner surface of the container is observed to be nearly 120°c at all times. as- suming 10 percent of the heat generated in the heater is lost through the insulation, (a) express the differential equation and the boundary conditions for steady one-dimensional heat conduction through the container, (b) obtain a relation for the variation of temperature in the container material by solving the differential equation, and (c) evaluate the outer surface tempera- ture of the container. also determine how much water at 100°c this tank can supply steadily if the cold water enters at 20°c.

Calculate the work done by an external agent during an isothermal compression of 1.00 mol of oxygen from a volume of 22.4 l at 10∘c and 1.0 atm pressure to 16.8l
