An earthquake is the shaking and trembling that results from the movement of rock beneath earth's surface. earthquakes most commonly occur near tectonic plate boundaries.

why is this most likely the case?
a.
earthquakes can only happen near volcanic eruptions, and most volcanoes occur on or near plate boundaries.

b.
many plate boundaries are bordered or covered by the ocean. water from the ocean seeps into earthquake fault lines, softening the rock materials so that they can move and cause earthquakes.

c.
tectonic plates move along, against, or away from each other at their boundaries. these movements produce earthquakes.

d.
seismic waves transmit through different media at different speeds. subduction zones at plate boundaries are ideal for transmission of these waves.

Iam a bacterium. i cause stomach cramps and diarrhea. i am caused by eating rotten foodssuch as chicken, fish, or eggs. sometimes turtles carry my bacteria.what am i?

When is a chart legend used a. all the time b. whenever you are comparing data that is the same c. whenever you are comparing multiple sets of data d. only for hand-drawn charts

Now you’re on your own. include a short summary of this section with plots in your lab report. write a matlab script file to do steps (a) through (d) below. include a listing of the script file with your report. 1 the soundsc(xx,fs) function requires two arguments: the first one (xx) contains the vector of data to be played, the second argument (fs) is the sampling rate for playing the samples. in addition, soundsc(xx,fs) does automatic scaling and then calls sound(xx,fs) to actually play the signal. mcclellan, schafer, and yoder, dsp first, 2e, isbn 0-13-065562-7. prentice hall, upper saddle river, nj 07458. c 2015 pearson education, inc. 4 mcclellan, schafer and yoder, signal processing first. prentice hall, upper saddle river, new jersey, 2003. c 2003 prentice hall. (a) generate a time vector (tt) to cover a range of t that will exhibit approximately two cycles of the 4000 hz sinusoids defined in the next part, part (b). use a definition for tt similar to part 2.2(d). if we use t to denote the period of the sinusoids, define the starting time of the vector tt to be equal to t , and the ending time as ct . then the two cycles will include t d 0. finally, make sure that you have at least 25 samples per period of the sinusoidal wave. in other words, when you use the colon operator to define the time vector, make the increment small enough to generate 25 samples per period. (b) generate two 4000 hz sinusoids with arbitrary amplitude and time-shift. x1.t / d a1 cos.2
