Nuclear forces are small-distance forces and have t… Rank them based on the order in which a probe would encounter them when traveling from Earth to the Sun's surface, from first encountered to last. B) Higher temperature would cause the rate of nuclear fusion to rise, which would increase the internal pressure, causing the core to expand and cool until the fusion rate returned to normal. There is no evidence for this. The Sun's core would start to heat up and the rate of fusion would increase even more. corona, chromosphere, photosphere, convection zone, radiation zone, core.

Nuclear fusion in the core keeps the temperature and the pressure inside the Sun at a high enough level so that gravity is balanced. Because of the electromagnetic force, the two protons will. Why do sunspots appear dark in pictures of the Sun? In the late 1800s, Kelvin and Helmholtz suggested that the Sun stayed hot thanks to gravitational contraction. In this fusion reaction, two protons (1 H) collide to form a deuteron (a nucleus of deuterium, 2 H), with the liberation of a positron (the electron’s positively charged antimatter counterpart, denoted e +). Does fusion occur only under extremely high temperatures? However, some energy is released from the upper layers of the solar atmosphere. What processes are involved in the sunspot cycle?
