Both waves would increase right? That seems correct since the water and air temp both equally changed.
The correct answer for this question is letter "E.. The frequency of the resultant wave decreases." The magnetic fields inside the two solenoids compare can give t<span>he frequency of the resultant wave decreases, given two solenoids, with current twice as great and 4 times as many coils and 3 times long.</span>
Answer:
0.00417 kW/K or 4.17 W/K
Second law is satisfied.
Explanation:
Parameters given:
Rate of heat transfer, Q = 2kW
Temperature of hot reservoir, Th = 800K
Temperature of cold reservoir, Tc = 300K
The rate of entropy change is given as:
ΔS = Q * [(1/Tc) - (1/Th)]
ΔS = 2 * (1/300 - 1/800)
ΔS = 2 * 0.002085
ΔS = 0.00417 kW/K or 4.17 W/K
Since ΔS is greater than 0, te the second law of thermodynamics is satisfied.
