Answer :
1318.31 J is the work produced by the Carnot engine each cycle.
Briefing
Given;
reservoir for high temperatures, Th = 435 k
River water temperature, Tl = 280 k
every cycle, absorbed heat energy, Q = 3700 J
Calculate the amount of work completed every cycle as;
W=Q(T1/Tn)
Where;
W is the completed work.
Q represents the total heat absorbed each cycle.
The cold liquid's temperature is Tl.
The hot reservoir's temperature is T.
w= Q( 1-T1/Th)
w= 3700 (1-280/435)
W= 3700(1-0.6437)
W =1318.31J
As a result, the carnot engine produces 1318.31 J of work each cycle when functioning under the current circumstances.
