When an object is heated, its particles move faster, increasing its volume and causing thermal expansion. What is the Coefficient of Linear Expansion?a.
It is the additional volume resulting from thermal expansion.
b.
It is the ratio between the change in length and the change in temperature caused by thermal expansion.
c.
It is the number of atomic particles moving in thermal expansion.
d.
It is the rate of temperature change caused by thermal expansion.
e.
It is the rate of change in length due to thermal expansion.

A technician from an electronics company is working on a circuit involving three capacitors in series. The capacitors have capacitances of 6μF, 8μF, and 12μF, respectively. Assuming the potential difference applied to the capacitors is 60V, determine the charge stored in each capacitor and the equivalent capacitance of the series configuration.

An electric car was developed to be a more sustainable alternative to combustion cars, which use non-renewable resources. This car travels in a straight line, starting from an initial position of 20 meters and reaching a final position of 120 meters. Calculate the position variation (Δx) of this car during the journey.
