What is the value of g at the surface of this star? (You may enter your calculation using scientific notation

he weight of a star is usually balanced by two forces: the gravitational force, acting inward, and the force created by nuclear reaction, acting outward. Over a long period of time, the force due to nuclear reactions gets weaker, causing the gravitational collapse of the star and crushing atoms out of existence. Under such extreme conditions, protons and electrons are squeezed to form neutrons, giving birth to a neutron star. Neutron stars are massively heavy-a teaspoon of the substance of a neutron star would weigh 100 million metric tons on the Earth.  What is the value of g at the surface of this star?

Compute the value of g at a height of 4RE above the surface of the earth, given that the mass and radius of the earth (RE) have their usual values.*1 point0.39 m/s^20.42 m/s^20.49 m/s^23.90 m/s^2

The value of '  g ' at certain height  h above the free surface of earth is  x4 where  x is the value of '  g ' at the surface of earth. The height  h is

An astronomer is trying to estimate the surface temperature of a star with a radius of 5.0×108m5.0×108m by modeling it as an ideal blackbody. The astronomer has measured the intensity of radiation due to the star at a distance of 2.5×1013m2.5×1013m and found it to be equal to 0.055W/m20.055W/m2 . Given this information, what is the temperature of the surface of the star?

Compute g for the surface of a planet whose radius is double that of the earth and whose mass is also double that of the earth.
