Answer:
h=2.86m
Explanation:
In order to give a quick response to this exercise we will use the equations of conservation of kinetic and potential energy, the equation is given by,
![\Delta PE_i + \Delta KE_i = \Delta PE_f +\Delta KE_f](https://tex.z-dn.net/?f=%5CDelta%20PE_i%20%2B%20%5CDelta%20KE_i%20%3D%20%5CDelta%20PE_f%20%2B%5CDelta%20KE_f)
There is no kinetic energy in the initial state, nor potential energy in the end,
![mgh+0=0+KE_f](https://tex.z-dn.net/?f=mgh%2B0%3D0%2BKE_f)
In the final kinetic energy, the energy contributed by the Inertia must be considered, as well,
![mgh = (\frac{1}{2}mv^2+\frac{1}{2}I\omega^2)](https://tex.z-dn.net/?f=mgh%20%3D%20%28%5Cfrac%7B1%7D%7B2%7Dmv%5E2%2B%5Cfrac%7B1%7D%7B2%7DI%5Comega%5E2%29)
The inertia of the bodies is given by the equation,
![I=\frac{m(R_1^2+R^2_2)}{2}](https://tex.z-dn.net/?f=I%3D%5Cfrac%7Bm%28R_1%5E2%2BR%5E2_2%29%7D%7B2%7D)
![I=\frac{2(0.2^2+0.1^2)}{2}](https://tex.z-dn.net/?f=I%3D%5Cfrac%7B2%280.2%5E2%2B0.1%5E2%29%7D%7B2%7D)
![I=0.05Kgm^2](https://tex.z-dn.net/?f=I%3D0.05Kgm%5E2)
On the other hand the angular velocity is given by
![\omega =\frac{v}{R_2}=\frac{4}{1/5} = 2rad/s](https://tex.z-dn.net/?f=%5Comega%20%3D%5Cfrac%7Bv%7D%7BR_2%7D%3D%5Cfrac%7B4%7D%7B1%2F5%7D%20%3D%202rad%2Fs)
Replacing these values in the equation,
![(0.5)(9.8)(h) =\frac{1}{2}*0.5*4^2+\frac{1}{2}*0.05*20^2](https://tex.z-dn.net/?f=%280.5%29%289.8%29%28h%29%20%3D%5Cfrac%7B1%7D%7B2%7D%2A0.5%2A4%5E2%2B%5Cfrac%7B1%7D%7B2%7D%2A0.05%2A20%5E2)
Solving for h,
![h=2.86m](https://tex.z-dn.net/?f=h%3D2.86m)
The answer is oil and water. If you want I could give you the reason too
The answer of this question is called uplift i.e the rising of rock layers in geology is called uplift.
Uplift is the process in which there will be vertical elevation of earth surface due to various natural processes occurring inside the surface of earth like earth quakes. Sometimes uplift is also caused by the mountain building which hampers the balance of a particular region.
In the process of uplift,the rocks normally metamorphic rocks present underground will be brought up to the earth surface.The enhanced elevation will cause erosion of lot of materials on the surface of earth.

Answer:
Seismic waves
Explanation:
seismic waves are not represented by electromagnetic graphs, nor can they be reflected on an electromagnetic spectrum. Visible light, radio waves, and microwaves are all electromagnetic waves, which are represented by graphs and electromagnetic spectrums.
