The answer is position 3, because it is at its lowest point.
Potential Energy is “stored energy.” It is energy that is ready to be converted or released as another type of energy. We most often think of potential energy as gravitational potential energy. When objects are higher up, they are ready to fall back down. When you stretch an object and it has a tendency to return to its original shape, it is said to have elastic potential energy. Chemical potential energy is the stored energy in a substance’s chemical structure that can be released in a chemical reaction or as heat.

Answer:
0.655 m
13.468°C
Explanation:
v = Speed of sound at 20.0°C = 343 m/s (general value)
For one both end open we have the expression
![L=\dfrac{\lambda_1}{2}\\\Rightarrow L=\dfrac{\dfrac{v}{f_1}}{2}\\\Rightarrow L=\dfrac{\dfrac{343}{261.6}}{2}\\\Rightarrow L=0.655581039755\ m](https://tex.z-dn.net/?f=L%3D%5Cdfrac%7B%5Clambda_1%7D%7B2%7D%5C%5C%5CRightarrow%20L%3D%5Cdfrac%7B%5Cdfrac%7Bv%7D%7Bf_1%7D%7D%7B2%7D%5C%5C%5CRightarrow%20L%3D%5Cdfrac%7B%5Cdfrac%7B343%7D%7B261.6%7D%7D%7B2%7D%5C%5C%5CRightarrow%20L%3D0.655581039755%5C%20m)
The length of the flute is 0.655 m
Beat frequency is given by
![\Delta f=f_1-f_2\\\Rightarrow 3=261.6-f_2\\\Rightarrow f_2=261.6-3\\\Rightarrow f_2=258.6\ Hz](https://tex.z-dn.net/?f=%5CDelta%20f%3Df_1-f_2%5C%5C%5CRightarrow%203%3D261.6-f_2%5C%5C%5CRightarrow%20f_2%3D261.6-3%5C%5C%5CRightarrow%20f_2%3D258.6%5C%20Hz)
Velocity of the wave is
![v=f_2\lambda_1\\\Rightarrow v=258.6\times \dfrac{343}{261.6}\\\Rightarrow v=339.066513761\ m/s](https://tex.z-dn.net/?f=v%3Df_2%5Clambda_1%5C%5C%5CRightarrow%20v%3D258.6%5Ctimes%20%5Cdfrac%7B343%7D%7B261.6%7D%5C%5C%5CRightarrow%20v%3D339.066513761%5C%20m%2Fs)
The temperature is given by
![T=273(\dfrac{v}{331})^2\\\Rightarrow T=273(\dfrac{339.066513761}{331})^2\\\Rightarrow T=286.468227799\ K=286.468227799-273=13.468227799^{\circ}C](https://tex.z-dn.net/?f=T%3D273%28%5Cdfrac%7Bv%7D%7B331%7D%29%5E2%5C%5C%5CRightarrow%20T%3D273%28%5Cdfrac%7B339.066513761%7D%7B331%7D%29%5E2%5C%5C%5CRightarrow%20T%3D286.468227799%5C%20K%3D286.468227799-273%3D13.468227799%5E%7B%5Ccirc%7DC)
The temperature of the room is 13.468°C
Answer:
The sweet food changed because the molecules were able to move fast enough to overcome the attraction between them with its molecules now moving away from each other.
Explanation:
We are told that the sweet food has a strong attraction between its molecules, and the sour food has a weak attraction between its molecules.
This means that the molecules in the sweet food would be moving at a faster rate than in the sour food because of the strong forces of attraction. Therefore, the molecules in the sweet food would be moving far away from each other hence the change of phase.
