A traveling wave on a taut string with a tension force T, is given by the wave function: y(x,t) = 0.05sin(rtx-100rt), where x and y are in meters and t is in seconds. If the linear mass density of the string is given by µ = 0.01 kg/m, then the tension force on the string is, 10 N 25 N O 0.5 N O 1N O 100 N
Properties of sound
A sound wave is a mechanical wave (or mechanical vibration) that transit through media such as gas (air), liquid (water), and solid (wood).
Quality Of Sound
A sound or a sound wave is defined as the energy produced due to the vibrations of particles in a medium. When any medium produces a disturbance or vibrations, it causes a movement in the air particles which produces sound waves. Molecules in the air vibrate about a certain average position and create compressions and rarefactions. This is called pitch which is defined as the frequency of sound. The frequency is defined as the number of oscillations in pressure per second.
Categories of Sound Wave
People perceive sound in different ways, like a medico student takes sound as vibration produced by objects reaching the human eardrum. A physicist perceives sound as vibration produced by an object, which produces disturbances in nearby air molecules that travel further. Both of them describe it as vibration generated by an object, the difference is one talks about how it is received and other deals with how it travels and propagates across various mediums.

A simple pendulum is set into motion at
two different times with different initial
conditions. The first time: the bob is in
its equilibrium position and is given an
initial velocity +2 m/s. The maximum
height reached by the bob is h1,max
and the period of motion is T1. The
second time: the bob is in its
equilibrium position and is given an
initial velocity +6 m/s. The maximum
height reached by the bob is h2,max
and the period of motion is T2. Assume
that the motion is simple harmonic,
which of the following is true?
h2,max
= 4h1,max and T2 = T,

A simple pendulum is made of a 2 m-
string and a bob of mass m. At t = 0,
the pendulum is at its equilibrium
position and is given an initial velocity v
= 0.2 m/s. The maximum angular speed,
O'max, is:
