Make a histogram, using a bin width of ten, to display the bowling scores for these 28 players: 116, 109, 81, 99, 72, 101, 89, 112, 76, 93, 86, 104, 98, 114, 74, 97, 107, 87, 115, 71, 105, 78, 84, 91, 83, 103, 94, 96.

Asample of silver (with work function ? = 4.52 ev) is exposed to an ultraviolet light source (? = 200 nm), which results in the ejection of photoelectrons. what changes will be observed if: silver is replaced with copper (? = 5.10 ev) more photoelectrons ejected no photoelectrons are emitted fewer photoelectrons ejected more energetic photoelectrons (on average) less energetic photoelectrons (on average)
