Awindow has a glass surface of 2907 cm2 and a thickness of 5.6 mm. find the rate of energy transfer by conduction through this pane when the temperature of the inside surface of the glass is 71◦f and the outside temperature is 81 ◦f. assume the thermal conductivity of window glass is 0.8 j/s · m · ◦ c . answer in units of kw

part bfind the rate of energy transfer for the same inside temperature and an outside temperature of 0◦f.

Assume that two of the electrons at the negative terminal have attached themselves to a nearby neutral atom. there is now a negative ion with a charge -2e at this terminal. what are the electric potential and electric potential energy of the negative ion relative to the electron? the electric potential and the electric potential energy are both twice as much. the electric potential is twice as much and the electric potential energy is the same. the electric potential is the same and the electric potential energy is twice as much. the electric potential and the electric potential energy are both the same. the electric potential is the same and the electric potential energy is increased by the mass ratio of the oxygen ion to the electron. the electric potential is twice as much and the electric potential energy is increased by the mass ratio of the oxygen ion to the electron.
