You are shocked to learn that the Sun (which has a mass of 1M⊙) and Betelgeuse (with a mass of 11M⊙) have both become black holes overnight. Which black hole would have a larger event horizon and why? What do you experience if you fly your spaceship towards the Betelgeuse black hole? Describe any effects on you or the spaceship What would an observer on the other side of the galaxy see when looking at the black holes against the background of the rest of the stars in the Milky Way?
Molten metal at 2000 C is poured using crucible. The liquid metal jet has a diameter of 3 mm with an insulation shield of 5 cm diameter. There is a slit of 30 degrees around the insulation shield. The temperature inside the room is 30 C and the shield is 700 C. Assuming black bodies, find the net heat transfer between jet and shield, jet and room, shield and the room. One of the steps is wrong A) Resistance network is required to be built B) To find the view factor between metal and shield , ratio of the angles is used C) View factors are one of the most important steps to solve the problem D) None of the above E) Slit doesnot participate in radiation
