- Gravitational forces are affected by two variable. List these two variable and indicate how they can lead to the formation of black holes. Use the word "event horizon" in your answer and indicate what it means.If a neutron star has a radius of 15 km and rotates 748 times a second, what is the speed of the surface at the neutron star's equator as a fraction of the speed of light?The redshift due to the Doppler effect is caused by sources of light obscured by interstellar dust. sources of light moving away from the Solar System. an effect not yet believed to be understood. sources of light moving at right angles to the Solar System. sources of light moving toward the Solar System.
