The aluminum alloy (2024-t6) absorber plate is 6 mm thick and well insulated on its bottom. the top surface of the plate is sepa
rated from a transparent cover plate by an evacuated space. the tubes are spaced a distance / of 0.20 m from each other, and water is circulated through the tubes to remove the collected energy. the water may be assumed to be at a uniform temperature of 7z 60c. under steady-state operating conditions for which the qhw radiation heat flux to the surface is trad 800 w/m2 , what is the maximum temperature on the plate and the heat transfer rate per unit length of tube? note that trad represents the net effect of solar radiation absorption by the absorber plate and radiation exchange between the absorber and cover plates. you may assume the temperature of the absorber plate directly above a tube to be equal to that of the water.

Base in your question about the magnetic field of the Earth near the equator where as its almost horizontally to the north and has magnitude of B=0.5x10^-4t, the answer is <span>Velocity of electron will be westwards.</span>
The work done is negative as the force is applied in the forward direction and the displacement of the hand is in the backward direction.
The work done is positive as the work is done on the baseball by Carlton. Moreover, both the force applied and the displacement of Carlton are in a straight line in the forward direction.
The work done in this case is zero as Carlton rides with constant speed, the Kinetic energy too remains constant and hence net work done is zero.
The work done in this case is positive as the work is done on the baseball by Carlton and as the velocity changes its Kinetic energy also varies wit it.
Also the force applied and the displacement of Carlton in this case are in the directed to the same path.
