Final answer:
Without specific details, it is not possible to rank the frictional forces accurately. However, for the fundamental forces, the correct ranking from greatest to least is: gravity, Earth-Sun; electrostatic, Earth-Sun; electrostatic, hydrogen; gravity, hydrogen.
Step-by-step explanation:
Understanding Frictional Forces
Friction is a resistive force that occurs when two surfaces are in contact. It is important to note that frictional forces will always oppose motion or attempted motion between the surfaces in contact. This resistance can arise due to the roughness of the surfaces, as well as due to the adhesive forces between the molecules of the objects involved, meaning even smooth surfaces experience friction. In terms of ranking frictional forces, we need more specific details about the surfaces and the normal force to make a comparison.
Understanding Fundamental Forces
Four fundamental forces mentioned in the question are gravitational and electrostatic forces both between Earth and the Sun and between a proton and an electron in a hydrogen atom. Since gravity is the weakest of the four fundamental forces when considering elementary particles, the gravitational force between the proton and electron would be the least. The electrostatic force between a proton and electron, due to their charges, is significantly stronger at the atomic level. Moreover, considering the masses and distances involved, the gravitational force between the Earth and the Sun is stronger than the electrostatic force between them. Thus, the correct ranking from greatest to least would be: gravity, Earth-Sun; electrostatic, Earth-Sun; electrostatic, hydrogen; gravity, hydrogen.
