Question

29) Suppose a group of students performed the Standing Wave experiment and made a graph of T (Tension) (Y-axis) vs. V2 (velocity squared) (X-axis). They made a linear adjustment and obtained a slope with a value of 0.043. Calculate the value of the linear density of the string.

1. In an experiment to study standing waves, you use a string
whose mass per length is µ = (1.8 ± 0.1) × 10−3kg/m. You look at
the fundamental mode, whose frequency f is related to the length L
and tension T of the string by the following equation L = 1 2f s T
µ .
You make a plot with L on the y-axis and √ T on the x-axis, and
find that the best fitting line is...

Open the Wave on a String PhET simulation.
Set the following parameters:
Simulation
PAUSED
Damping
None
Tension
High
Rope’s End
No End
Source
Oscillate
Ruler
Enabled
Amplitude
0.5 cm
Set the frequency of oscillation to 1.5 Hz. Run the simulation
by clicking on the Play/Pause button. Measure the wavelength of the
wave, using the ruler and the Play/Pause button.
Repeat step 3 but increase the frequency to 3 Hz. Determine the
wavelength of the wave. Summarize your data in Data...

The waves that stay in the middle by reflecting and changing
phase, without canceling out, are called standing waves because
they take shape that does not vary with time.
6- The set of free frequencies in which a system can vibrate is
known as natural frequencies.
7- Transverse waves in the string vibrate to the medium in the
direction of wave propagation.
The wavelength vs frequency graph has the form of? A- straight
line B- circle C- Parable D- Square...

Two waves traveling in opposite directions on a stretched rope
interfere to give the standing wave described by the following wave
function:
y(x,t) = 4 sin(2πx) cos(120πt),
where, y is in centimetres, x is in meters, and t is in seconds.
The rope is two meters long, L = 2 m, and is fixed at both
ends.
In terms of the oscillation period, T, at which of the following
times would all elements on the string have a zero vertical...

In an experiment, a group of students will determine the
dielectric constant of paper. They have the following materials
available, as well as other materials traditionally available in a
high school physics lab.
_____ Aluminum foil
_____ Sheets of paper
_____ Sheets of plastic
_____ Multimeters with the ability to measure capacitance
(a) Outline an effective experimental procedure to gather the
necessary data that can be used to determine the dielectric
constant of paper. Place a check mark next to...

An experiment on memory was performed, in which 16 subjects were
randomly assigned to one of two groups, called "Sentences" or
"Intentional". Each subject was given a list of 50 words. Subjects
in the "Sentences" group were told to form multiple sentences, each
using at least two words from the list, and to keep forming
sentences until all the words were used at least once. Subjects in
the "Intentional" group were told to spend five minutes memorizing
as many of...
