Modelling the structure of the atom is important because modeling replaces the real system with something similar but easier to examine. Option B
<h3>What is modeling?</h3>
A model is a representation of reality. We know that a model could help us to recreate reality in a manner that we could be able to relate fully with it. A model could be used also a means of explanation.
The atomic models that we have usually help us to understand more abut the atom. Therefore, modelling the structure of the atom is important because modeling replaces the real system with something similar but easier to examine. Option B

The part of the ear where the sound wave converted into electrical impulse would be the cochlea. This part is the auditory portion of the inner ear which produces nerve impulses in response to sound vibrations. Hope this answers the question. Have a nice day.
Answer:
t = 3.29 seconds
Explanation:
It is given that,
Height of the Eiffel tower is 60 m
Initial speed of a euro, u = 2 m/s
It will move under the action of gravity in the downward direction. Firstly, we can find the final velocity as follows :
![v^2-u^2=2ad\\\\v=\sqrt{u^2+2ad} \\\\v=\sqrt{(2)^2+2\times 9.81\times 60} \\\\v=34.36\ m/s](https://tex.z-dn.net/?f=v%5E2-u%5E2%3D2ad%5C%5C%5C%5Cv%3D%5Csqrt%7Bu%5E2%2B2ad%7D%20%5C%5C%5C%5Cv%3D%5Csqrt%7B%282%29%5E2%2B2%5Ctimes%209.81%5Ctimes%2060%7D%20%5C%5C%5C%5Cv%3D34.36%5C%20m%2Fs)
Let t is the time taken by the euro to hit the ground. It can be calculated as :
![v=u+at\\\\t=\dfrac{v-u}{a}\\\\t=\dfrac{34.36-2}{9.81}\\\\t=3.29\ s](https://tex.z-dn.net/?f=v%3Du%2Bat%5C%5C%5C%5Ct%3D%5Cdfrac%7Bv-u%7D%7Ba%7D%5C%5C%5C%5Ct%3D%5Cdfrac%7B34.36-2%7D%7B9.81%7D%5C%5C%5C%5Ct%3D3.29%5C%20s)
Hence, it will take 3.29 seconds to hit the ground.
