Question

for water waves

For every trial, the waves travel for exactly the same amount of time to the same pointfrom each of the taps. Doesn’t that mean every “Wave state” should be a “trough?” Explain.

Using a PHET light waves stimulator: Turn only bottom light on
then measure how long it takes for the center of the trough of the
wave to be at that point you marked. Turn the bottom light off and
allow the waves to dissipate. Next, turn on the light at the top
and allow the simulation to run for exactly the amount of time
measured. Record the “state of the wave” at your marked point. Is
it a trough, a...

These two waves travel along the same string: y1 = (4.37 mm)
sin(2.17πx - 440πt) y2 = (5.75 mm) sin(2.17πx - 440πt +
0.754πrad).
What are (a) the amplitude and
(b) the phase angle (relative to wave 1) of the
resultant wave? (c) If a third wave of amplitude
5.45 mm is also to be sent along the string in the same direction
as the first two waves, what should be its phase angle in order to
maximize the amplitude...

Today, the waves are crashing onto the beach every 6 seconds.
The times from when a person arrives at the shoreline until a
crashing wave is observed follows a Uniform distribution from 0 to
6 seconds. Round to 4 decimal places where possible. a. The mean of
this distribution is b. The standard deviation is c. The
probability that wave will crash onto the beach exactly 3.3 seconds
after the person arrives is P(x = 3.3) = d. The probability...

Suppose you are interested in determining the amount of time in
minutes that commuters travel to school. You would like to use a
95% confidence that your sample mean is within 1.5 minutes of the
true population mean. If the commute times have a standard
deviation of 10 minutes, how many students should you include in
your sample?

1)Today, the waves are crashing onto the beach every 5.6
seconds. The times from when a person arrives at the shoreline
until a crashing wave is observed follows a Uniform distribution
from 0 to 5.6 seconds. Round to 4 decimal places where
possible.
a. The mean of this distribution is
b. The standard deviation is
c. The probability that wave will crash onto the beach exactly
0.4 seconds after the person arrives is P(x = 0.4)
=
d. The probability...
