Two neutron stars are separated by a distance of 1.0 x 1012 m. They each have a mass of 1.0 x 1030 kg and a radius of 1.0 x 105 m. They are initially at rest with respect to each other. As measured from that rest frame, how fast are they moving when (a) their separation has decreased to one-half its initial value and (b) they are about to collide

If a neutron star and a white dwarf has a total mass of 1M. If the white dwarf has a radius of 9 x 106 m and the neutron star has a radius of 11 km. i) Compare the surface gravity of both stars. ii) What is the density of the neutron star? iii) Assuming the neutron star is entirely made up of neutrons, and that the interparticle separation of a gas of density n is l = n-1/3. How...
Two identical particles, each having charge +q, are fixed in space and separated by a distance d. A third particle with charge -Q is free to move and lies initially at rest on the perpendicular bisector of the two fixed charges a distance x from the midpoint between those charges (see figure below). tq -Q a) Show that if х ıs small compared with d, the motion of Q is simple harmonic along the perpendicu arbi sector. Submit a e...
A neutron of mass 1.67 x 10-27 kg, moving with velocity 2.0 x 104 m/s, makes a head-on collision with a boron nucleus of mass 17.0 x 10-27 kg. The boron nucleus is initially at rest. If the collision is elastic, what fraction of the original kinetic energy of the neutron is transferred to the boron nucleus?
Two black holes (the remains of exploded stars), separated by a distance of 10.0 AU (1 AU = 1.50 ✕ 1011 m), attract one another with a gravitational force of 6.70 ✕ 1025 N.The combined mass of the two black holes is 5.60 ✕ 1030 kg. What is the mass of each black hole? largest value kg smallest value kg
Two spherical objects, both of mass m and radius R, have center-to-center separation 4R and are initially at rest. No external forces act. The spheres accelerate towards one another until they collide. (a) What is the speed of each object just before the collision? Find the exact answer using energy methods. (b) Using the final speed from part (a), and assuming the acceleration is roughly constant and equal to the initial acceleration, calculate an upper limit on the time it...

[Q2 20 points] A and B devices separated by a distance d- 50 m measured in the reference frame S where they are at rest. The following sequence of events occurs: (K) A sends light signal towards B. (L) As soon as the signal is received by B, B sends a signal back to A. (M) A receives the signal from B The reference frame S', coincides with S at time t = t, 0 and is in motion with...
