Describe one advantage and one disadvantage of having the water level "sweep" (move) through the resonance position. 5. a tuning fork has a frequency of 384 hz. the speed of sound is 343 m/s. the maximum length of an air column is 80 cm. how many resonances can be observed? lab journal template experiment a: wavelength - determine resonance locations. rvoir ermo- neter a tuning fork is held over the open end of a long tube. the tube is partly filled with water and the tube is connected to a reservoir that is used to change the height of the water in the tube. when the reservoir is high, the water in the reservoir drains into the tube, raising the water level. when the reservoir is low, water drains out of the tube into the reservoir, lowering the water level. the flow of water is not instantaneous, so it is possible to sweep through a range of water levels in a controlled way over the course of a few seconds.

hi i’m sorry to call us today so we will get back with y’all and we will have to do it haha omg was the day

the only real purpose of sputnik 1 was to beat the us into space. we were getting close to launching a useful satellite, explorer 1 - which launched on january 31, 1958. the ussr had to beat that, so they launched sputnik 1 on october 4, 19

russian is not my first language, so i'm afraid i can't write out an answer in russian, but hopefully you can find a way to do so. here's my best translation of the problem: you're given a plot of a particle's position in one-dimensional space over time, and you're asked to find either the total distance traveled by the particle after 6 seconds had elapsed, or the total displacement of the particle after 6 seconds.

if you want the total distance traveled, you would first need to determine the particle's velocity as a function of time, then integrate that over the 6-second interval. we know the position function is quadratic with roots at 0 and 6, so we have

where is unknown. because the position is parabolic, there is symmetry about the midpoint at , and we know that

so that the position function is

which means the velocity is

then the total distance traveled is

so the total distance traveled is 20 m.

on the other hand, if you want to find displacement: the particle starts at and ends at , so its displacement is 0.
