Yes that is a balaned equation
Answer:
2.73414 seconds
467622.66798 J
Explanation:
t = Time taken
u = Initial velocity
v = Final velocity
s = Displacement
g = Acceleration due to gravity = 9.81 m/s² = a
![v=60\times \dfrac{1609.34}{3600}=26.822\ m/s](https://tex.z-dn.net/?f=v%3D60%5Ctimes%20%5Cdfrac%7B1609.34%7D%7B3600%7D%3D26.822%5C%20m%2Fs)
![mgh=\dfrac{1}{2}mv^2\\\Rightarrow h=\dfrac{v^2}{2g}\\\Rightarrow h=\dfrac{26.822^2}{2\times 9.81}\\\Rightarrow h=36.66766\ m](https://tex.z-dn.net/?f=mgh%3D%5Cdfrac%7B1%7D%7B2%7Dmv%5E2%5C%5C%5CRightarrow%20h%3D%5Cdfrac%7Bv%5E2%7D%7B2g%7D%5C%5C%5CRightarrow%20h%3D%5Cdfrac%7B26.822%5E2%7D%7B2%5Ctimes%209.81%7D%5C%5C%5CRightarrow%20h%3D36.66766%5C%20m)
![s=ut+\frac{1}{2}at^2\\\Rightarrow 36.66766=0t+\frac{1}{2}\times 9.81\times t^2\\\Rightarrow t=\sqrt{\frac{36.66766\times 2}{9.81}}\\\Rightarrow t=2.73414\ s](https://tex.z-dn.net/?f=s%3Dut%2B%5Cfrac%7B1%7D%7B2%7Dat%5E2%5C%5C%5CRightarrow%2036.66766%3D0t%2B%5Cfrac%7B1%7D%7B2%7D%5Ctimes%209.81%5Ctimes%20t%5E2%5C%5C%5CRightarrow%20t%3D%5Csqrt%7B%5Cfrac%7B36.66766%5Ctimes%202%7D%7B9.81%7D%7D%5C%5C%5CRightarrow%20t%3D2.73414%5C%20s)
or
![v=u+at\\\Rightarrow t=\dfrac{v-u}{a}\\\Rightarrow t=\dfrac{26.822-0}{9.81}\\\Rightarrow t=2.73414\ s](https://tex.z-dn.net/?f=v%3Du%2Bat%5C%5C%5CRightarrow%20t%3D%5Cdfrac%7Bv-u%7D%7Ba%7D%5C%5C%5CRightarrow%20t%3D%5Cdfrac%7B26.822-0%7D%7B9.81%7D%5C%5C%5CRightarrow%20t%3D2.73414%5C%20s)
The time taken is 2.73414 seconds
The potential energy is given by
![U=mgh\\\Rightarrow U=1300\times 9.81\times 36.66766\\\Rightarrow U=467622.66798\ J](https://tex.z-dn.net/?f=U%3Dmgh%5C%5C%5CRightarrow%20U%3D1300%5Ctimes%209.81%5Ctimes%2036.66766%5C%5C%5CRightarrow%20U%3D467622.66798%5C%20J)
The change in potential energy is 467622.66798 J
A place that is cold because of an increase in altitude has a mountain area climate or simply, mountain climate. An area that is high in altitude typically has a colder temperature because of the increased amount of rainfall they have. Also, air tends to cool as it rises in temperature.
Answer:
the answer is C
Explanation:
we know this because if you compare the graphs and look at the direction. it isn't always in the explanation or the few sentences they gave you at the top. also, look at the waves, you can see in Davids drawing that it is directly straight up, A and B do not represent that. A isn't even a valid answer. Notice also in A that the arrow is going in the completely different direction than in Davids drawing. B is also going a different direction even though it is only turned a little bit although if it was straight up like Davids drawing then it would most likely be a correct answer. C does have one arrow going a different direction but look at how it has two, showing in which if the waves were to turn then the arrow is still valid
