Answer:
(a) 0.525
(b) 1750J
Explanation:
Coefficient of Performance (COP) = Q2/(Q1 - Q2)
Q1 = heat rejected to the surrounding = 1750J
Q2 = heat absorbed in the environment = 585K
COP = 585/(1700 - 585) = 585/1115 = 0.525
(b). Heat expelled to the surrounding (room) = 1750J

'Ampere' is the unit of current. That's the rate at which
electrons travel in the circuit ... the number of electrons
every second. If you wanted the actual amount or number
of electrons, you'd need to know the length of time too.
It doesn't matter whether we're talking about a parallel or
series circuit.
The range is: [26.86-0.02, 26.86+0.02] = [26.84, 26.88]
