Explanation:
<u>Elastic Potential Energy
</u>
Is the energy stored in an elastic material like a spring of constant k, in which case the energy is proportional to the square of the change of length Δx and the constant k.
![\displaystyle PE = \frac{1}{2}k(\Delta x)^2](https://tex.z-dn.net/?f=%5Cdisplaystyle%20PE%20%3D%20%5Cfrac%7B1%7D%7B2%7Dk%28%5CDelta%20x%29%5E2)
Given a rubber band of a spring constant of k=5700 N/m that is holding potential energy of PE=8600 J, it's required to find the change of length under these conditions.
Solving for Δx:
![\displaystyle \Delta x=\swrt{\frac{2PE}{k}}](https://tex.z-dn.net/?f=%5Cdisplaystyle%20%5CDelta%20x%3D%5Cswrt%7B%5Cfrac%7B2PE%7D%7Bk%7D%7D)
Substituting:
![\displaystyle \Delta x=\sqrt{\frac{2*8600}{5700}}](https://tex.z-dn.net/?f=%5Cdisplaystyle%20%5CDelta%20x%3D%5Csqrt%7B%5Cfrac%7B2%2A8600%7D%7B5700%7D%7D)
Calculating:
![\displaystyle \Delta x=\sqrt{3.0175}](https://tex.z-dn.net/?f=%5Cdisplaystyle%20%5CDelta%20x%3D%5Csqrt%7B3.0175%7D)
![\boxed{\displaystyle \Delta x=1.74\ m}](https://tex.z-dn.net/?f=%5Cboxed%7B%5Cdisplaystyle%20%5CDelta%20x%3D1.74%5C%20m%7D)
Answer: A
Explanation: We know that f=p*n
f=50*300=15000 Hz = 15kHz.
Have a great day! <3
Water gets to the leaves in the tops of the tallest trees by something called the cohesion-tension theory. Water has two very unique properties called adhesion and cohesion. Cohesion is the tendency of water molecules to stick together with one another. The water sticks together, leaving no room for air, strengthening the "force" of the water going up the tree. The water also sticks to the sides of the xylem inside the tree. In addition to these properties, there are also the factors of negative and positive water potential. For more information, look up more details of the cohesion-tension theory.
