What is 3 kelpers law? And how to help Newton for gravitation?
1. using Newton’s Law of Universal Gravitation and some kinematics calculation we can calculate the mass of the planet. For this, use this equation below: ?planet =(9.340×1024)×(vmax)×(Pstar)1/3×(Mstar)2/3 Given: - vmax = 1.5 m/s - Pstar = 3.5 days - Mstar = 1.148 Msun, where Msun = 1.98847×1030 kg. This calculation is not shown.
1.) In what way(s) is Einstein's general theory of relativity superior to Newton's theory of universal gravitation? For each way, give an example of a case where Einstein's theory provides a more accurate description of physical phenomena than does Newton's. (Select all that apply.) A.) Newton's theory originally held that the orbit of a spherical object about another will be an open curve for which the point of closest approach slowly precesses. Einstein's theory correctly predicts that gravitational forces lead to orbits of closed ellipses. B.) Einstein's theory correctly predicts the deflection of light passing near a massive object, while Newton's theory predicts a deflection that is one-half the observed deflection. C.) Einstein's theory correctly predicts that the orbit of a spherical object about another will be an open curve for which the point of closest approach slowly precesses.

New Horizons was launched by NASA lastJanuary 19, 2006 to a mission to the dwarfplanet Pluto. On July 15, 2015, it flew 12,500km above the surface of Pluto, making it thefirst successful spacecraft to explore the dwarfplanet. Explain how the gravity of Jupiterhelped New Horizons to propel faster to Pluto.
Use Newton’s law of gravity to calculate the force of gravity between you and Earth. Convert your answer, which will be in newtons, to pounds, using the conversion 4.45 N equals 1 pound (1 lb). What do you normally call this force? Please consider you are 55 kg. b) The Moon’s mass is 7.4 x 1022 kg and its radius is 1700 km.

A geosynchronous orbit is one in which the satellite stays in the same relative position above the earth, as the earth rotates. To do so, the satellite needs to have an orbital period of 1 day. Given that the moon has an orbital period of 27.3 days and a semi-major axis of 384,000 km, determine the radius of a geosynchronous orbit using Kepler's 3rd law. Enter your answer in km.
