A block of 10 kg is dragged across a horizontal surface with an applied force of 50 N, parallel to the surface. The coefficient of kinetic friction between the block and the surface is 0.3. What is the value of the kinetic friction force and what is the resulting acceleration of the block?a.
Kinetic friction force = 30 N and Acceleration = 2 m/s²
b.
Kinetic friction force = 20 N and Acceleration = 3 m/s²
c.
Kinetic friction force = 15 N and Acceleration = 3.5 m/s²
d.
Kinetic friction force = 25 N and Acceleration = 2.5 m/s²
e.
Kinetic friction force = 40 N and Acceleration = 1 m/s²

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.
