9. What is a Kerr black hole?
10. Where did the term 'black hole' come from?
EXERCISE1.To become a black hole, an object must have a mass greater than three times the mass of the sun. This is because the forces attributed to quantum mechanicswill keep anything smaller from becoming dense enough. But we can calculate what the Schwarzschild radius of an object would be as if it could become a black hole. Using equation (2) from Lab 9 instructions, calculate the Schwarzschild radius of the following objects:a)A 60 kg person.
b) The Earth (6 x 1024kg)R
c) Jupiter (2 x 1027kg)R
d) The Sun (2 x 1030kg)R
e) A star with three solar masses.
