Directions: c = 299,792,458 m/s Little Boy was the atomic weapon dropped on Hiroshima toward the end of WWII. It had a yield (energy release) of 15,000 tons of TNT or 6.27E13 Joules. How much mass went “missing” when it detonated?

The magnitude of the amount of energy released by burning a fuel source, measured in energy per unit mass, is called its fuel value. note that the fuel value is the negative of the isobaric specific heat of combustion for the fuel. if all the energy obtained from burning 1.23 pounds of butane with a fuel value of 10.85 kcal/g is used to heat 128.0 kg of water at an initial temperature of 18.3 °c, what is the final temperature? note that 1 lb = 453.6 g.

Exercise 2. find the wavelength of a photon emitted when an electron jumps from the n = 3 energy level down to the n = 2 energy level. where is this photon in the electromagnetic spectrum?

Examples of states of consciousness include a. daydreaming b. dreaming during sleep c. hypnosis d. all of the above
