Detailed explanation-1: -Which statement disagrees with Laplace’s hypothesis of the sun’s formation? The sun’s mass moved toward the outer edge of it. What plays an important role in the formation of a star system?
Detailed explanation-2: -what is now called Laplace’s nebular hypothesis, a theory of the origin of the solar system. Laplace imagined that the planets had condensed from the primitive solar atmosphere, which originally extended far beyond the limits of the present-day system.
Detailed explanation-3: -Which statement correctly describes a difference in our solar system’s inner planets and outer planets due to gravitational effects? The inner planets are larger.
Detailed explanation-4: -Laplace’s model begins with the Sun already formed and rotating and its atmosphere extending beyond the distance at which the farthest planet would be created. Knowing nothing about the source of energy in stars, Laplace assumed that the Sun would start to cool as it radiated away its heat.
