Which of the following statements are part of the explanation why a small increase in mass leads to a large increase in luminosity for stars? select all that apply o faster moving hydrogen atoms hit each other more frequently and are more likely to fuse when they impact each other o greater mass leads to a stronger force of gravity o with a denser core, hydrogen atoms are packed more closely together and thus hit each other more frequently more compression of the core of the star raises its density and temperature. o at a higher temperature, hydrogen atoms are moving faster o stronger self gravity leads to greater compression of the star's core.
