  10. Alma didn’t have the best people skills • Alma 32:14 And now, as I said unto you, that because ye were compelled to be humble ye were blessed, do ye not suppose that they are more blessed who truly humble themselves because of the word?

  11. Alma didn’t have the best people skills • Alma 32:25 For I do not mean that ye all of you have been compelled to humble yourselves; for I verily believe that there are some among you who would humble themselves, let them be in whatsoever circumstances they might.

  12. Alma didn’t have the best people skills • Alma 39:1 And now, my son, I have somewhat more to say unto thee than what I said unto thy brother; for behold, have ye not observed the steadiness of thy brother, his faithfulness, and his diligence in keeping the commandments of God? Behold, has he not set a good example for thee?

  13. Hold a rope taut. Which of the following will get the pulse to the end faster? • Move hand up and down faster • Move hand up and down a greater distance • Use a lighter rope • Use less Tension http://phet.colorado.edu/simulations/sims.php?sim=Wave_on_a_String

  14. Two guitar strings of the same length have the same tension, but one has four times the mass of the other. The speed of a wave on the heavier guitar string is __________ than the lighter string. • Slower • The same • faster

  15. Which of the following statements is true assuming the same rope and tension? • The higher the frequency, the longer the wavelength • The lower the frequency, the longer the wavelength. • Higher frequency waves travel faster than lower frequency waves. • 1 and 3 • 2 and 3

  16. Two strings, one thick and the other thin, areconnected to form one long string. A wavetravels along the string and passes the pointwhere the two strings are connected. Whichof the following changes at that point: • frequency • period • wavelength
