Acertain refrigerator, operating between temperatures of −3.00°c and +23.8°c, can be approximated as a carnot refrigerator. what is the refrigerator's coefficient of performance? cop = (b) what if? what would be the coefficient of performance if the refrigerator (operating between the same temperatures) was instead used as a heat pump? cop =

Ok what do you need with

Answer: 1.4 seconds which is the third optionexplanation: current is defined as the flow of charge per timetherefore, the equation that relates current, charge and time can be expressed as follows: i = δq / δtwhere: i is the current given = 1.8 ampereδq is the charge given = 2.5 coulombδt is the time required for the flow of the given charges to give the 1.8 ampere.substitute with the givens in the above equation to get the time as follows: 1.8 = 2.5 / δtδt = 2.5 / 1.8 = 1.38888 which is approximately 1.4 secondshope this was !
