What’s #16 asking me and how do i solve it?

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.

Make a drawing of the electric field lines around a positive charge, then make a second drawing of the electric field lines around a negative charge.
