Consider steady heat transfer between two large parallel plates at constant temperatures of t1 = 210 k and t2 = 150 k that are l = 2 cm apart. assume that the surfaces are black (emissivity ε = 1). determine the rate of heat transfer between the plates per unit surface area assuming the gap between the plates is filled with atmospheric air.

Choose the correct general statement concerning the total potential and kinetic energy at any point along the arc of swing. the total energy at any point along the arc of swing of the pendulum is always less than 12 joules. the total energy at any point along the arc of swing of the pendulum is always more than 12 joules. the total energy at any point along the arc of swing of the pendulum is always equal to 12 joules. not enough information to determine
