(Originais Teachy 2023) - Question Medium of Physics

In an art exhibition room, a flat mirror is installed on the wall and moves horizontally towards a painting positioned 2 meters away from the mirror initially. The speed of the mirror relative to the wall is 0.5 m/s. Considering only the horizontal movements and using the laws of reflection, (a) calculate the speed of propagation of the image of the painting relative to the mirror; (b) if the mirror's speed is reversed and it moves away from the painting at the same speed of 0.5 m/s, calculate again the speed of propagation of the image of the painting relative to the mirror; (c) explain the relationship between the speeds found in (a) and (b) and why this occurs.

An architect is designing a theater room with a concave mirror on the back wall. The mirror has a focal length of 5 meters. The architect wants a sculpture, which will be placed 10 meters from the mirror, to be seen reflected in the mirror at a distance of 2 meters from the ground. Considering that the mirror is at ground level, what should be the height of the sculpture? Use the Gauss equation and the linear magnification equation to solve the problem.

In the universe, stellar evolution is a determining factor for the origin and distribution of chemical elements and for the emergence of solar and planetary systems. Suppose you are an astronomer studying a newly discovered star in a distant galaxy, and that star will go through all the stellar phases until its death. (a) Describe each of the main phases of the evolution of this star, from its formation from a cloud of gas and dust to its death as a white dwarf, neutron star, or black hole. (b) Explain how chemical elements are produced and distributed throughout this process. (c) Evaluate the possible implications of this stellar evolution on the emergence of planetary systems and the existence of life, considering the necessary conditions for the formation of solar and planetary systems.
