A fridge operates between temperatures of 4°C and 27.0°C. This particular fridge has a COP of 5.80. (a) If 500 of work is done by the compressor in the fridge to extract heat from inside the fridge, how much heat is removed from inside the fridge?
(answer in Jules)
(b) How much heat is dumped by the fridge into the surroundings?
(answer in Jules)

(d) What is the maximum possible COP that would be achieved by an ideal fridge operating between the two temperatures specified above?

Learning goal: to understand newton's 1st law. newton's principia states this first law of motion: an object subject to no net force maintains its state of motion, either at rest or at constant speed in a right line. this law may be restated as follows: if the sum of all forces acting on an object is zero, then the acceleration of that object is zero. mathematically this is just a special case of the 2nd law of motion, f⃗ =ma⃗ , when f⃗ =0. when studying newtonian mechanics, it is best to remember the 1st law in two ways: if the net force (i.e., sum of all forces) acting on an object is zero, the object will keep moving with constant velocity (which may be zero). if an object is moving with constant velocity, that is, with zero acceleration, then the net force acting on that object must be zero. complete the following sentences to see if you can apply these ideas. part a if a car is moving to the left with constant velocity, one can conclude that
