There are two types of seismic waves associated with every
earthquake, called P and S waves. They travel in every direction
away from the source of an Earthquake called the epicenter. Because
they each travel with different speeds, seismologists can determine
the distance from a seismic station to an epicenter. An earthquake
occurred in an area when a P wave travels at 5 km/s and the S wave
travels at 3 km/s. A seismic station measures an SP lag time...
1. Define the following terms: earthquake, seismic wave, seismograph, seismogram. 2. What are the basic types of seismic waves? Which seismic wave travels along the surface of Earth? Which seismic wave travels through Earth's interior? 3. Which seismic wave travels fastest? Which seismic wave travels slowest? 4. What is the difference between an earthquake epicenter and an earthquake focus? 5. How many different earthquake recordings are needed to locate an earthquake epicenter?
Fluid Mechanics:
The speed of shallow water waves in the ocean (e.g., seismic sea
waves or tsunamis) depends only on the still water depth
and the acceleration due to gravity. Derive an expression for wave
speed.
When a seismometer station records the various seismic waves
from an earthquake event, which type of seismic wave arrives
FIRST?
The P-waves
The S-waves
The surface (Raleigh and Love) waves
The tidal waves
The lazy waves
Mergesort is known to be one of the fastest algorithms for
sorting lists of data. In fact, the runtime of mergesort is
proportional to n· logn where n is the size of the list to be
sorted. Bubblesort, on the other hand is a much slower algorithm,
since it's runtime is proportional to n2 , where n is
the size of the list to be sorted.
As an experiment, mergesort is run on a slow computer,
bubblesort is run on...
The velocity of waves on a string is 95.0 m/s. If the frequency of standing waves is 160 Hz, how far apart are two adjacent nodes? If two successive overtones of this vibrating string are 240 Hz and 320 Hz, what are the frequency of the fundamental and the length of the string?
The speed of waves on a string is 97 m/s. If the frequency of
standing waves is 485Hz, how far apart are the two adjacent
nodes?

Suppose the alphabet is S = {A B C D} and the known probability
distribution is PA = 0.3, PB = 0.1,
PC = 0.5, and PD = 0.1. Decode the Huffman
coding result {11000010101110100} to the original string based on
the probability distribution mentioned above. The codeword for
symbol “D” is {111}. Please writing down all the details of
calculation.
Q4. Tiger Woods is known for having one of the fastest driving
swings in Golf (among other things). In fact, his Tee-off ball
speed was recorded to be 122 MPH.
Determine what Tiger Wood’s angular velocity and acceleration
are for the club. He is 1.85 meters tall. (Refer to the
Anthropometry slides to estimate his shoulder height)
Shoulder height = 1.5133
122 MPH = 54.54 m/s
