please solve. I need help with part D and Part E

Large stars can explode as they finish burning their Part A Part B nuclear fuel, causing a supernova. The explosion blows away the outer layers of the star. According to Newton's third law, the forces that push the outer layers away have Consider a neutron star with a mass equal to the sun, a What is g at the surface of this neutron star? reaction forces that are inwardly directed on the core of radius of 13 km, and a rotation period of 1.0 s. What is the star. These forces compress the core and can cause the speed of a point on the equator of the star? Express your answer to three significant figures and the core to undergo a gravitational collapse. The include the appropriate units. gravitational forces keep pulling all the matter together Express your answer with the appropriate units. tighter and tighter, crushing atoms out of existence. Under View Available Hint(s) these extreme conditions, a proton and an electron can be View Available Hint(s) squeezed together to form a neutron. If the collapse is halted when the neutrons all come into contact with each 9 = 7.85x1011 m Urot = 82 km other, the result is an object called a neutron star, an entire star consisting of solid nuclear matter. Many neutron stars rotate about their axis with a period of Submit Previous Answers 1 s and, as they do so, send out a pulse of Submit Previous Answers electromagnetic waves once a second. These stars were discovered in the 1960s and are called pulsars. Correct Correct Part E Part D What is the radius of a geosynchronous orbit about the neutron star? Part C How many revolutions per minute are made by a Express your answer to three significant figures and satellite orbiting 1.0 km above the surface? include the appropriate units. A stationary 1.0 kg mass has a weight on earth of Express your answer in revolutions per minute. View Available Hint(s) 9.8 N. What would be its weight on the star?
