A glass prism is used in a laboratory experiment to separate the colors that make up white light. The prism is in the shape of an equilateral triangle with sides of length 10 cm and a refractive index of 1.5. A monochromatic light beam is incident on the prism and emerges with an angular deviation. For this experiment, consider that the light beam hits the first face of the prism at a 45º angle. (a) Calculate the angle of refraction on the first face of the prism, applying Snell's Law; (b) Determine the angle of incidence of the light beam on the second face of the prism as it passes through it; (c) Using the information obtained in the previous steps, calculate the total angular deviation of the light beam passing through the prism.

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.
