The length of nylon rope from which a mountain climber is suspended has a force constant of 1.2 × 104 N/m. Part (a) What is the frequency, in Hz, at which he bounces, given his mass and the mass of his equipment is 98 kg? 1.76 Part (b) How much would this rope stretch, in centimeters, to break the climber's fall if he free-falls 2.4 m before the rope starts to stretch? 0.705 Part (c) What is the frequency, in Hz, at which he bounces, given his mass and the mass of his equipment is 98 kg if the rope is twice as long? Part (d) How much would this rope stretch, in centimeters, to break the climber's fall if he free-falls 2.4 m before the rope runs out of slack if the rope was twice the length? I only need part C and D answered. I have the correct answer for part A and B at the end of the question.
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.
