After our Sun exhausts its nuclear fuel, its ultimate fate may be to collapse to a white dwarf state, in which it has approximately the same mass as it has now but a radius equal to roughly the size of the Earth's radius. (a) Calculate the average density of this white dwarf if the Sun were to collapse to a radius of 6.18 x 10 m. O kg/m3 (b) Calculate the free-fall acceleration at its surface. Cm/s2 (c) Calculate the...

4、15 pts Some five billion years from now, the Sun will have exhausted its hydrogen fuel and blown off its outer layers. The remaining core of the sun will be a hot, dense white dwarf star. Assuming that the white dwarf has a radius roughly equivalent to Earth's and a remaining mass of 0.60 Mo, what is the acceleration due to gravity at its surface? (Mo is the present day mass of the sun). Compare this value to-g. the acceleration...

Stars much heavier than our sun will not form white dwarf, but collapse further, becoming (if condition are right) neutron stars. They result from the supernova explosion of a massive star, combined with gravitational collapse, that compresses the core past white dwarf star density to that of atomic nuclei. Eventually neutron degeneracy pressure stabilizes the collapse, just as the electron does for white dwarfs. The Fermi Energy is given by where Z/A =1 and V corresponds to volume. The neutron...

When a star exhausts its nuclear fuel, the gravitational force causes it to col- lapse. As the density increases, the star enters the electron degeneracy limit and the electron degeneracy pressure may be able to support the star against gravitational col- lapse. The gravtiational pressure of N nucleons of mass MN is 1/3 P, - G(NM)?(45 V-4/3 Determine the radius of the star assuming that there are 2 nucleons per electron. Evaluate the radius for N - 1057, which is...

Assume that the Earth's orbit is a circle of radius 1.5 X 10' m (iv) Calculate the Gravitational Force between the Earth and the Sun. (v) Compare the Gravitational Force to that net force from section (ii) above. Given that F mg (vi) Calculate the acceleration due to...

Problem 1. A block of mass m = 735 g is located on an incline which makes an angle of 40 with the horizontal The friction coefficient between the block and the incline is K = 0.21. The block is released and it is let slide down the incline. (a) Draw a free body diagram and identify all forces acting on the block. Find the acceleration of the block (b) If the block moves d = 0.42...
