Answer:
The gravity collapsing the core, increases pressure causing the fusion of hydrogen to helium. The newly formed helium creates outward pressure. The pressure balances the gravitational inward pull. This is the hydrostatic equilibrium and it occurs throughout the main sequence phase.
Answer:
Explanation:
Set the equations for work and kinetic energy equal to each other. Work equals force times distance and kinetic energy equals one-half the mass of the object times its velocity squared, so F_d = (m_ ÷ _2)_v2. Substitute the measurements for force, distance and mass into the equation.
