A Physics student decides to conduct an experiment to estimate the gravitational acceleration of Earth. He drops a ball from a height of 10 meters and measures the time it takes for the ball to touch the ground. If he timed 1.4 seconds for the ball to reach the ground, what is the closest value of Earth's gravitational acceleration in m/s², according to the experiment? Use the formula: h = 0.5 * g * t².a.
9.8 m/s²
b.
10.2 m/s²
c.
8.7 m/s²
d.
9.1 m/s²
e.
11.5 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.
