A 1.30-m string of weight 0.0125 N is tied to the ceiling at its upper end, and the lower end supports a weight W. Neglect the very small variation in tension along the length of the string that is produced by the weight of the string. When you pluck the string slightly, the waves traveling up the string obey the equationy(x, t)=(8.50mm)cos(172rad⋅m−1x−2730rad⋅ s−1t)Assume that the tension of the string is constant and equal to W. How much time does it take a pulse to travel the full length of the string?What was the weight W?How many wavelengths are on the string at any instant of time?What is the equation for waves traveling down the string?

0.25N
0.036 m
![y(x, t)=Acos[kx -wt]\\\\becomes\\\\y(x , t)= Acos[(172 rad.m)x + (2730 rad.s)t]](/tpl/images/0643/0128/2eac2.png)
![without, unit\\\\y(x , t)= Acos[172x + 2730t]](/tpl/images/0643/0128/65498.png)

Assume that a person skiing high in the mountains at an altitude of h = 15100 ft takes in the same volume of air with each breath as she does while walking at sea level. determine the ratio of the mass of oxygen inhaled for each breath at this high altitude compared to that at sea level. assume that the air composition (i. e. % of air that is oxygen) is the same at sea level as it is at 15100 ft.

Scientist have use computer models to create a series of maps that show how susceptible coastal cities in island countries are to the sea rising at different levels. the map shows that a 1 meter rise would swap cities all along the us eastern seaboard. a 6-meter sea level rise with sub merge a large part of florida. thermal expansion has already raise the oceans 10 to 20 centimeters the most likely cause, directly and indirectly, for such a rise in sea level is
