Document Summary
Please read the problems carefully and answer them in the space provided. Write on the back of the page, if necessary. Problem 1 (10 pts total, 2 points/part, no partial credit on each part, no justification needed) Potentially useful information: atomic mass of 2 atomic mass of 3 atomic mass of 4 mass of proton in mev/c2 is 937. 873 mass of neutron in mev/c2 is 939. 565 mass of electron in mev/c2 is 0. 511. While in europe, where the household voltage is 240 v, you buy a light bulb rated at 60. When you return home to america, where the household voltage is 120 v, if you use this light bulb, how will the brightness of this light bulb compare to the standard american. 60 w light bulb? (assume the resistance of the european bulb does not change depending on the applied voltage. ) After graduation, you take a job at ed"s transmorgorizer emporium.
