Consider a pulsar, a collapsed star of high extremely high density with mass M equal to that of the Sun (2.0E30 kg), a radius R=14000m, and a rotational period T=0.023sec. A 15500kg, man made satellite is planed to place in orbit of this start. A)Find the gravity at the surface of the Star? B)The escape velocity from the surface of the star. C) The height of the satellite? D) The orbital speed of the satellite? E) To what size the pulsar must collapse to become a black hole?

Expert Solution

In the above stated question, as nothing is mentioned about the orbit of the satellite, the only assumption we can make is that it is a geostationary satellite.

When the escape velocity of any given object becomes greater than the speed of light, i.e., impractical speed to achieve, the other objects never escape from the gravitational influence of that object, hence it acts like a black hole.

Consider the final iron core of a massive star with a mass M Fe = 1.5M and radius R Fe = 3 × 10 8 cm. When this core collapses, the initial collapse stops when the central core with a mass M core = 0.7M reaches a density ρ = 3 × 10 13 g cm −3 . At this density the core bounces, which drives a shock with an energy E bounce = 10 51 erg into the infalling...

Consider a wire of uniform density and mass M shaped into a quarter circle of radius R.The wire is located in the xy plane, with the origin at the focus of the quarter circle (i.e at the center of the circle of which the wire is part). Choose the x axis parallel to the line that connects the endpoints of the wire, so that the y-z plane is a plane of reflection symmetry for the wire. This means that the...

Problem 4. Consider a simple solar system that contains one star (mass M) and one planet (mass m) in a circular orbit with radius r. The planet orbits at speed v. (v can be computed in terms of G, M, m, and r using Kepler’s 3rd Law and/or Newton’s Law of Gravitation.) Due to conservation of momentum, as the planet changes its velocity vector, the star’s velocity vector will also change. Astronomers can detect a star’s changing velocity from its...
