Erything in Earth's system can be placed into one of four major subsystems: land, water, living things, or air. These four subsystems are called "spheres." Specifically, they are the "lithosphere" (land), "hydrosphere" (water), "biosphere" (living things), and "atmosphere" (air).
Explanation:
It is given that,
Frequency of vibration, f = 215 Hz
Amplitude, A = 0.832 mm
(a) Let T is the period of this motion. It is given by the following relation as :
![T=\dfrac{1}{f}](https://tex.z-dn.net/?f=T%3D%5Cdfrac%7B1%7D%7Bf%7D)
![T=\dfrac{1}{215}](https://tex.z-dn.net/?f=T%3D%5Cdfrac%7B1%7D%7B215%7D)
![T=4.65\times 10^{-3}\ s](https://tex.z-dn.net/?f=T%3D4.65%5Ctimes%2010%5E%7B-3%7D%5C%20s)
(b) Speed of sound in air, v = 343 m/s
It can be given by :
![v=f\times \lambda](https://tex.z-dn.net/?f=v%3Df%5Ctimes%20%5Clambda)
![\lambda=\dfrac{v}{f}](https://tex.z-dn.net/?f=%5Clambda%3D%5Cdfrac%7Bv%7D%7Bf%7D)
![\lambda=\dfrac{343\ m/s}{215\ Hz}](https://tex.z-dn.net/?f=%5Clambda%3D%5Cdfrac%7B343%5C%20m%2Fs%7D%7B215%5C%20Hz%7D)
![\lambda=1.59\ m](https://tex.z-dn.net/?f=%5Clambda%3D1.59%5C%20m)
Hence, this is the required solution.

I have asked question in my profile please tell me the answer
Answer:
i am just answering what this guy said this answer isnt mine ok -v-/ Both soaps and emulsifiers contain only one nonpolar tail group Both soaps and emulsifiers consist of fatty acid chains and a polar head group Both soaps and emulsifiers work in the same manner
Soaps contain two polar tail groups, but emulsifiers have only one polar tail group ,Soaps contain only one nonpolar tail group, but emulsifiers have two nonpolar tail group
Answer:
The answer is 1020 meters.
Explanation:
The values given by the problem are:
1. T= The falling time of the rock [Seconds]
2. H=The sound velocity constant [meter/second]
The Velocity normal formula is
V=H/T
340=H/3
340*3=H
This solution considers the physic of the traveling wave sound but not really the rock falling problem, because the problem ask for the height of the cliff not even more.
