Observations show that a celestial body traveling at 1.2 × 106 mi/h appears to be describing about point B a circle of radius equal to 60 light years. Point B is suspected of being a very dense concentration of mass called a black hole. Determine the ratio MB/MS of the mass at B to the mass of the sun. (The mass of the sun is 330,000 times the mass of the earth, and a light year is the distance traveled by light in 1 year at 186,300 mi/s.)

classical mechanics : Captain James T. Kirk of Star Trek fame spent a large portion of his time mining for planets that contained heavy metals after leaving active duty. In order to accomplish this, he put his spaceship into an elliptical orbit around the planet and measured its density (= total mass/volume; a sphere's volume is equal to 4/3pi r^(3)), where r is its radius). Significant concentrations of important heavy metals were probably present on planets with densities higher than normal. The radius of the planet, the period of the orbit, the minimum and greatest distances of his ship from the planet's centre, or r_min and r_max, were the only measurements he took to arrive at this conclusion. The engines of the ship were deactivated during his journey in the elliptic orbit. Ignore any effects the local star might have on the motion. Kirk also knows the mass of his ship. Explain how he was able to determine the planet’s density using this method.
Please answer the equation step by step and include a proper diagram if needed. Usse gravity as 9.8m/s^2. 4. Mars and Earth, at their closest theoretical positions, are 54.6 million km apart. The mass of Earth is 5.97 x 10 kg, and the mass of Mars is 6.39 x 10ª kg. A satellite of mass 9550 kg is to be placed such that the forces of gravity between the satellite and the two planets are equal in magnitude. Determine two possible locations for this to occur.
Write down an expression for the gravitational filed strength of a planet of radius R and density ρ.
A particle has γ=18,399. a) Calculate c-v in m/s. (I would have asked for 1 - v/c, making the answer dimensionless, but the system doesn't seem to take numbers that small. Gamma is chosen to make the particle extremely close to the speed of light.) If your calculator gives problems, you might want to solve the appropriate equation for c-v or c(1 - v/c) and use an approximation. b) In a race to the moon, by 3/4ths the distance, light is one or ten meters ahead of the particle. We routinely approximate mass as zero, gamma as infinite, and speed as the speed of light. ("Massless particles" -- gamma and m have to be eliminated from the expressions. Light is a true massless particle.) If a massless particle has momentum 1,739 MeV/c, calculate its energy in MeV. Thank you so much!!
The Millennium Falcon is approximately 35.8 m long. There are conflicting reports, but the Falcon made the Kessel Run in approximately 12.86 parsecs. This is an odd unit to measure speed with as a parsec is a unit of length equal to 3.26 light-year. The science FICTION comes in when you consider that ships in Star Wars use hyperdrive to travel faster than the speed of light, so they are able to make jumps through space. Han Solo picked difficult or dangerous points to jump between to make the trip so short. Let's imagine that the Millennium Falcon travels at 0.97c during the 12.86 parsec Kessel Run. What distance, in light-year, does an observer at the finish line measure for the trip? Don't forget to convert parsec to light-year. light-year What distance, in light-year, does Han Solo measure for the trip as he pilots the ship? light-year Which person measures the proper distance of the trip? Which person would measure the proper length of the Millennium Falcon? ✪

A Mars observing satellite is orbiting on a circular orbit at an altitude of 1000 km above Mars’s equator. Find satellite’s acceleration and velocity as seen from a deep space communications station located on Earth’s equator, when they are on a direct line of sight (see the Fig. below). Assume for simplicity that planetary orbits and their equatorial planes are all in the plane of ecliptic (that is all, motion is in a 2D plane). Earth radius is 6300 km, Mars radius 3400 km, Mars mass 6.4x1023 kg. Assume that all circular motions are counter clockwise (i.e., orbital motions of Earth and Mars, Earth spin, and satellite orbital motion).
Suppose you observe a binary system containing a main-sequence star and a brown dwarf. The orbital period of the system is 1 year, and the average separation of the system is 1 AU . You then measure the Doppler shifts of the spectral lines from the main-sequence star and the brown dwarf, finding that the orbital speed of the brown dwarf in the system is 23 times greater than that of the main-sequence star. How massive is the brown dwarf in kg?
A non-rotating black hole has an ‘edge’ at what’s called it’s Schwartzschildradius. For a black hole of mass M, the Schwartzschild radius isRSch = 2GM/(c^2) where G is the gravitational constant and c is the speed of light. Close to black holes, we really should use Einstein’s theory of gravity (General Relativity) instead of Newton’s, but Newton’s is still a good approximation.Using Newtonian Gravity, find the gravitational force on a mass m at theSchwartzschild radius of a black hole. (Your answer for this should look likeFgrav = an expression in terms of G, M, m, c and numbers.) Is the forcesmaller or larger for a more massive black hole?
