Newton's third law states that every action has an equal and opposite reaction. An example of this can be seen in car accidents: when two cars collide, the collision forces are equal and opposite. Additionally, when a driver brakes the car, the car is pushed forward with the same force that he is braking. Based on this information, which of the alternatives below correctly represents the application of Newton's third law?a.
When a bird flaps its wings, the air is pushed downwards and the bird is propelled upwards.
b.
When a man pushes a wall, the wall pushes the man with the same intensity of the push.
c.
When a person jumps into a pool, the impact of the water on the person pushes the water out of the pool.
d.
If an object is at rest, it will remain at rest until a force acts upon it.
e.
When an object is thrown upwards, it returns to the ground because the Earth exerts a gravitational force on it.

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.
