The Sun’s mass is 2.0 × 1030 kg, its radius is 7.0 × 105 km, and it has a rotational period of approximately 28 days. If the Sun should collapse into a white dwarf of radius 3.5 × 103 km, what would its period be if no mass were ejected and a sphere of uniform density can model the Sun both before and after?
C6M.9 Astar with mass M and radius R collides with another star of massM and radius R, and coalesce to form a new star at rest whose radius is R. Assume that initially the colliding stars had angular velocities with opposite direc- tions but the same magnitude | What is the magnitude and direction of the final star's angular velocity? (Express the magnitude as a fraction of )
A black hole is an object so massive that not even light can escape, one way to define the size of a black hole is by the Schwarzschild Radius, which is the radius at which the escape velocity is equal to the speed of light. If we were to condense the Earth into a black hole, what would be the size of its Schwarzschild Radius?
A brown dwarf star has 5 times the mass of the Sun packed into a sphere of diameter of 20 km. Compute for the surface gravity on this star.
Around 2.5 centuries ago, several physicists of the time came up with the notion of a dark star. This was a star so dense, with so much gravity, that not even light could escape. The calculations used Newtonian mechanics. In class, we calculated the escape speed from the surface of the earth or the distance from the sun, and the mass of the planet or star. Here, the process is partially reversed. Calculate the dark star radius from the mass of the star and the escape speed. Answer in kilometers. • c = 3*108 m/s • M = 3.7*1030 kg G = 2/3 * 10-10 N*m²/kg²
Suppose the Sun contracts (collapses) to a pulsar with radius 15 km. Estimate the period of rotation of the pulsar. The period of revolution of the Sun about its axis is 25.38 days (1 day = 24 hours). Compare the kinetic energies of rotation of the pulsar and of the Sun.
A certain white dwarf star was once an average star like our Sun. But now it is in the last stage of its evolution and is the size of our Moon but has the mass of our Sun. Part A Estimate gravity on the surface on this star.
Neptune has a mass of 1.0 × 1026 kg and is 4.5 × 10⁹ km from the Sun with an orbital period of 177.5 years. Planetesimals in the outer primordial solar system 4.5 billion years ago coalesced into Neptune over hundreds of millions of years. If the primordial disk that evolved into our present day solar system had a radius of 10¹1 km and if the matter that made up these planetesimals that later became Neptune was spread out evenly on the edges of it, what was the orbital period of the outer edges of the primordial disk? Express your answer rounded to the nearest year, and be sure not to do any rounding before expressing your final answer. P = years
Black holes are difficult to observewith telescopes because they, bydefinition, don’t emit or reflect any light. They can be found by look-ing for other nearby objects orbit-ing them, however. Here is a dia-gram of a star in a circular orbit around a black hole. a. The period of the star’s orbit is 90 days, and its orbital radius around the black hole isobserved to be 3.6 : ×10^11 m. Find the orbital velocity of the star in units of m/s. (You need to convert 90 days to seconds, first). The circumference of a circle is 2πr. b. The mass of the star is known to be 4 × 10^30 kg. Find the centripetal acceleration of thestar and the strength of the gravitational force on the star. c. Find the mass of the black hole.
Question 1 a. Suppose the Sun contracts (collapses) to a pulsar with radius 15 km. Estimate the period of rotation of the pulsar. The period of revolution of the Sun about its axis is 25.38 days (1 day = 24 hours). Compare the kinetic energies of rotation of the pulsar and of the Sun. Figure 1: Question 1(a) A pulsar star system b. A wheel on an extremely low friction slanted surface will slide without rotating. However, if the same surface is rough and having some friction the wheel will roll down (with rotation). Explain why, using free body diagram.
Physics A white dwarf is the remnant core of a previous star < 8 solar masses that has about the mass of the Sun but the radius of the Earth. What would be (1) the orbital speed and (2) the orbital period for a spacecraft in orbit just above the surface of the white dwarf?
The rate at which a nebular cloud rotates increases as the cloud collapses to form systems of stars and planets. Consider a small segment of a nebular cloud with a mass m of 1.9 x 1027 kg, tangential velocity vinitial equal to 6.8 km s¯1 located at an orbital distance rinitial = 2.5 x 104 km. After the cloud collapses, the same small segment is located at an orbital distance rinal = 3.2 x 10° km. Calculate the change of the rotational velocity, Ao, for the cloud segment, assuming perfectly circular orbits. Perform your work and report your solution using two significant figures. Δω- rad s-
