This is a mathematical problem by converting the distance from the sun to earth then using what ever is given!
The total mass of the Earth plus you while you're on the Earth is lighter than the sum of the masses of the Earth and you.
a) Why is this?
b) Assuming the gravitational binding energy is GMm/r - calculate the difference.
129. In 1999, scientists discovered a new class of black holes with
masses 100 to 10,000 times the mass of our sun but occu-
pying less space than our moon. Suppose that one of these
black holes has a mass of 1 × 10° suns and a radius equal to
one-half the radius of our moon. What is its density in grams
per cubic centimeter? The mass of the sun is 2.0 × 10º kg,
and the radius of the moon is 2.16 × 10° mi. (Volume of a

- During most of its lifetime, a star maintains an equilibrium size in which the inward force of gravity on each atom is balanced by an outward pressure force due to the heat of the nuclear reactions in the core. But after all the hydrogen "fuel" is consumed by nuclear fusion, the pressure force drops and the star undergoes a gravitational collapse until it becomes a neutron star. In a neutron star, the electrons and protons of the atoms are squeezed together by gravity until they fuse into neutrons. Neutron stars spin very rapidly and emit intense pulses of radio and light waves, one pulse per rotation. These "pulsing stars" were discovered in the 1960s and are called pulsars. A star with the mass (M=2.0×10^30kg) and size (R=3.5×10^8m) of our sun rotates once every 29.0 days. After undergoing gravitational collapse, the star forms a pulsar that is observed by astronomers to emit radio pulses every 0.200 s. By treating the neutron star as a solid sphere, deduce its radius.arrow_forwardDuring most of its lifetime, a star maintains an equilibrium size in which the inward force of gravity on each atom is balanced by an outward pressure force due to the heat of the nuclear reactions in the core.

As we have seen in the text, the conversion of four hydrogen atoms to one helium atom results in the conversion of about 0.02862 times the mass of a proton to energy. How much energy in joules does one such reaction produce? (See Appendix E for the mass of the hydrogen atom, which, for all practical purposes, is the mass of a proton.)arrow_forward
