1. The instructor informs Carey that his determination of the wave speed is lower then the actual value. The instructor suggests that he try the first overtone. Why would the instructor suggest this and how would it change the measurements and outcome?

2. Marcy then asks the instructor a question, "Why does it get louder at certain positions, but not others?" How should the teacher answer this question?

3. In the teacher's response they mention, "the natural frequency of the pipe". What does the teacher mean by this statement?

as we probably am aware that our atmosphere or air have various levels, each level has different gasses, and each gas has another porousness. at the point when the light originates from lower porousness to higher penetrability, it alters its course. with the goal that implies that when the light originates from the moon to the earth, it alters it's course a lot more occasions. it essentially implies that the state of the light piece of the moon is changed on the earth.

the old price per ounce is c/4.

the new price per ounce is c/3.6.

the ratio of the old price to the new one is

(c/4)/(c/3.6) = (c/c)×(3.6/4) = 0.9 . . = 9/10 . . "nine tenths" in either form
