at the surface of the red super giant star betelguese, the gravitational force 6-67x10
between the star and a 1.00 kg mass of hot gas is only 2.19 x 10-3 n. this is
because the mean radius of betelguese is so large. given that the mass of
betelguese is 20 times that of the sun, or 3.98 x 1031 kg, what is the mean radius of
betelguese?

The starship enterprise is caught in a time warp and spock is forced to use the primitive techniques of the 20th century to determine the specific heat capacity of an unknown mineral. the 125-g sample was heated to 96.3°c and placed into a calorimeter containing 85.9 g of water at 20.0°c. the heat capacity of the calorimeter was 14.2 j/k. the final temperature in the calorimeter was 24.5°c. what is the specific heat capacity (in j/g°c) of the mineral? enter to 4 decimal places.
