Brass is an alloy made from copper and zinc. A 0.59 kg brass candlestick has an initial temperature of 93.0 oC. If 1.85 x 104 J of energy is removed from the candlestick to lower its temperature to 5 oC, what will be the specific heat, in J/goC, of brass?

the answer for sodium is 0.186

the answer for rubidium is 0.251

question: ray weighs 100 kilograms, his wrestling partner, bobby, weighs 50 kilograms. if ray moves at 4 m s , how fast will bobby have to run at him to apply an equal amount of kinetic energy?

answer: 8 m/s he needs to run twice as fast to keep up so he has some work to do

explanation:   if the mass has units of kilograms and the velocity of meters per second, the kinetic energy has units of kilograms-meters squared per second squared.
