You overhear the following conversation Ty: “We created a diffraction pattern on the distant screen by illuminating a pair of long narrow slits with green light. The next instruction wants us to make the bright fringes of the diffraction envelope expand away from the center. I think we should find a different laser to do this – a red one would work well.” Sarah: “No, we shouldn’t use a different laser, we should just move the screen we’re making the...

You overhear a conversation between Mark and Anne in the gym. Mark is saying that he can bench press on average 200 pounds. Anne responds that on average she can bench press more. Mark then challenges her, saying "Show it!" Apparently, Anne keeps track of her data well, because she answers: "In the last n = 45 times, I pressed y = 205 with s2 = 24.5 pounds." She then suddenly turns around, looks at you, and says: "You are...

Your friend is belching the alphabet. Where you are standing, a distance of 2 meters from your friend, the peak sound level of their belching is 68.2 dB. You would like to move far enough away from them that you won’t have to hear their belching. Assuming that the belch noises approximate spherical waves, how far should you stand from your friend in order for the peak intensity of the sound to be the threshold of hearing, 10^−12 W/m2?
