A car participates in a race and, during a specific stretch, moves from point A to point B in 4 seconds. At the beginning of this stretch, the car is traveling at a speed of 20 m/s, while at the end, its speed is 40 m/s. Assuming that the acceleration is constant throughout the journey. Considering the situation presented, what is the value of the average vector acceleration of this car during the mentioned stretch?
a.
5 m/s²
b.
10 m/s²
c.
15 m/s²
d.
20 m/s²
e.
25 m/s²

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.
