Let's begin by calculating the mass of the puck, which will be needed at various points throughout this tutorial. Using the density of dry ice (1.50 g/cm3) and the dimensions of the puck, find the mass of the puck. Assume the height of the puck is 2.60 cm.

6–43 a food department is kept at 2128c by a refrigerator in an environment at 308c. the total heat gain to the food department is estimated to be 3300 kj/h and the heat rejection in the condenser is 4800 kj/h. determine the power input to the compressor, in kw and the cop of the refrigerator.

The magnitude of the poynting vector of a planar electromagnetic wave has an average value of 0.939 w/m^2 . the wave is incident upon a rectangular area, 1.5 m by 2.0 m, at right angles. how much total electromagnetic energy falls on the area during 1.0 minute?
