Explanation:
When hot water is poured on the can in a bucket of cold water, the can crushes off means it gets unshaped
True, because it is the state between solid and liquid
Answer:![x=\frac{x_m}{\sqrt{2}}](https://tex.z-dn.net/?f=x%3D%5Cfrac%7Bx_m%7D%7B%5Csqrt%7B2%7D%7D)
Explanation:
Given
initially mass is stretched to ![x_m](https://tex.z-dn.net/?f=x_m)
Let k be the spring Constant of spring
Therefore Total Mechanical Energy is ![\frac{kx_m^2}{2}](https://tex.z-dn.net/?f=%5Cfrac%7Bkx_m%5E2%7D%7B2%7D)
Position at which kinetic Energy is equal to Elastic Potential Energy
![K=\frac{mv^2}{2}](https://tex.z-dn.net/?f=K%3D%5Cfrac%7Bmv%5E2%7D%7B2%7D)
![U=\frac{kx^2}{2}](https://tex.z-dn.net/?f=U%3D%5Cfrac%7Bkx%5E2%7D%7B2%7D)
it is given
![k=U](https://tex.z-dn.net/?f=k%3DU)
thus ![2U=\frac{kx_m^2}{2}](https://tex.z-dn.net/?f=2U%3D%5Cfrac%7Bkx_m%5E2%7D%7B2%7D)
![2\times \frac{kx^2}{2}=\frac{kx_m^2}{2}](https://tex.z-dn.net/?f=2%5Ctimes%20%5Cfrac%7Bkx%5E2%7D%7B2%7D%3D%5Cfrac%7Bkx_m%5E2%7D%7B2%7D)
![2x^2=x_m^2](https://tex.z-dn.net/?f=2x%5E2%3Dx_m%5E2)
![x=\frac{x_m}{\sqrt{2}}](https://tex.z-dn.net/?f=x%3D%5Cfrac%7Bx_m%7D%7B%5Csqrt%7B2%7D%7D)
Li2O
Lithium is a metal with an oxidation number of 1+ and oxygen is a nonmetal with an oxidation number of 2-. Which chemical formula represents the compound formed by these two elements? Li2O is the correct answer because lithium has one valence electron and oxygen has six.
Hope this helped.
