Hawking Radiation Homework Problems






1. Using the equations for Hawking Radiation and the example on the previous page determine the mass of a blackhole that takes 1.26 x 1010 years to evaporate.

Note: This is the current estimated age of the universe.


2. Calculate the Schwardzchild Radius of such a blackhole in its infancy, ie when t=1.26 x 1010 years.


3. Calculate the Schwardzchild Radius, temperature, luminosity and energy released of the blackhole using the times in parts a, b and c.

a. 1 year before it evaporates

b. 1 second before it evaporates.

c. 1 x 10-20 seconds before it evaporates.
