- The typical core-collapse supernova has an energy budget of about 1046 J. This energy comes from the gravitational potential energy of an inner core with mass Mic, which collapses from an initial radius of 5 x 106 m down to the final radius of 50 km. Estimate Mic, in solar masses, for this to be a realistic energy source of the core-collapse supernova. You may assume that the density before the collapse is uniform. Discuss briefly how a Type la supernova is different from a core-collapse supernova from a massive star?Event Horizon is a region around a black hole where: group of answer choices: even light cannot escape. all the events are occurring speed of an object is close to speed of light. no physical object can pass through. r nothing can enter .Part A Assuming that these spectral lines correspond to the 656.46-nm hydrogen line in the rest frame, estimate the speed V of the center of mass of the binary system. Express your answer in kilometers per second to three significant figures .Part B Determine the mass M of each star. Express your answer in kilograms to one significant figure.

Explain your answer. a.) The mass of LV-426 is 1/4 that of Earth. b.) The mass of Earth is 1/4 that of LV-426. c.) A rock dropped from 10m would hit the ground faster on Earth. d.) A rock dropped from10mwould hit the ground faster on LV-426.4At the end of a massive star’s life, its core can undergo a catastrophic collapse that triggers a supernova explosion. The core remnant consists of about 1.4 solar masses’ worth of pure neutronsand is called a neutron star. What is the approximate radius of such a neutron star, if neutrons arereally like incompressible spheres?
