In an experiment conducted in the Physics Laboratory, a group of students found that a wooden block floated in water with half of its volume submerged. Next, the same block was placed in oil where they found that it floated with $$\frac{1}{4}$$ of its volume emerged. From this information, we can affirm that the specific mass of the oil is:

A motor operates according to the Carnot cycle between two thermal sources. The hot source is at a temperature of 500 K and the cold source at 300 K. Determine the efficiency of the motor, knowing that the efficiency of the Carnot cycle is calculated by the expression 1 - (Tcold/Thot), where Tcold and Thot are the temperatures of the cold and hot sources, respectively. Discuss briefly the importance of the maximum efficiency of the Carnot cycle in practical applications of thermal engines.
