- As an object falls into a black hole, tidal forces increase. Will these tidal forces always tear the object apart as it approaches the Schwarzschild radius? How does the mass of the black hole and size of the object affect your answer?arrow_forwardThe next step in deciding whether the object in Exercise 25.25 is a black hole is to estimate the density of this mass. Assume that all of the mass is spread uniformly throughout a sphere with a radius of 20 lighthours. What is the density in kg/km3? (Remember that the volume of a sphere is given by V=43R3 .) Explain why the density might be even higher than the value you have calculated. How does this density compare with that of the Sun or other objects we have talked about in this book?arrow_forwardHow can we calculate Schwarzschild radius?arrow_forward

Calculate the orbital velocity of the particle and express the answer in units of the speed of light.arrow_forwardWhat is Schwarzschild radius?arrow_forwardYou discover by dropping particles into it that the Event Horizon (Schwartzschild Radius) of a black hole is 171 km.

- Calculate the Schwarzschild Radius for each of the following: 1. A 3.3 X 108 solar-mass black hole in the center of a quasar 2. a 3.5 solar-mass black hole formed in a type II supernova 3. a mini-black hole with the mass of the moon 4. a black hole with the mass of you (estimate your mass to be 51.8 kg)arrow_forwardan introduction on what is the event horizon of a black holes?arrow_forward1. Let’s say we have a black hole with a mass 10 times that of the Sun (the Sun’s mass is 2 x 1030kg so the mass of the black hole is then 2 x1031 kg) Using the definitions for G and c what Schwarzschild radius of this black hole be? g=6.67 x 10-11 m3 kg-1 s-2 c=3 x 108 m s-1arrow_forward
