Explanation :
The heating curve shows how water changes from one state of matter to another based on temperature and the addition or removal of heat over time.
Initially, ice is heated until its temperature reaches
and changes to liquid state.
From the attached graph it is clear that until
the temperature will rise steadily. Here, the liquid begins to vaporize. Vaporization is the state of matter at which liquid state changes to the gaseous state.
So, E is the point which shows the gaseous state.

To solve this problem we will apply the concepts related to Reyleigh's criteria. Here the resolution of the eye is defined as 1.22 times the wavelength over the diameter of the eye. Mathematically this is,
![\theta = \frac{1.22 \lambda }{D}](https://tex.z-dn.net/?f=%5Ctheta%20%3D%20%5Cfrac%7B1.22%20%5Clambda%20%7D%7BD%7D)
Here,
D is diameter of the eye
![D = \frac{1.22 (539nm)}{5.11 mm}](https://tex.z-dn.net/?f=D%20%3D%20%5Cfrac%7B1.22%20%28539nm%29%7D%7B5.11%20mm%7D)
![D= 1.287*10^{-4}m](https://tex.z-dn.net/?f=D%3D%201.287%2A10%5E%7B-4%7Dm)
The angle that relates the distance between the lights and the distance to the lamp is given by,
![Sin\theta = \frac{d}{L}](https://tex.z-dn.net/?f=Sin%5Ctheta%20%3D%20%5Cfrac%7Bd%7D%7BL%7D)
For small angle, ![sin\theta = \theta](https://tex.z-dn.net/?f=sin%5Ctheta%20%3D%20%5Ctheta)
Here,
d = Distance between lights
L = Distance from eye to lamp
For small angle ![sin \theta = \theta](https://tex.z-dn.net/?f=sin%20%5Ctheta%20%3D%20%5Ctheta)
Therefore,
![L = \frac{d}{sin\theta}](https://tex.z-dn.net/?f=L%20%3D%20%5Cfrac%7Bd%7D%7Bsin%5Ctheta%7D)
![L = \frac{0.691m}{1.287*10^{-4}}](https://tex.z-dn.net/?f=L%20%3D%20%5Cfrac%7B0.691m%7D%7B1.287%2A10%5E%7B-4%7D%7D)
![L = 5367m](https://tex.z-dn.net/?f=L%20%3D%205367m)
Therefore the distance is 5.367km.
Answer:
Explanation:
There's a formula for this:
![F = k*displacement](https://tex.z-dn.net/?f=F%20%3D%20k%2Adisplacement)
F being force, k being the spring constant, and displacement being the change in x
We are given the force and the spring constant, so this is essentially isolating the Δx term. Do 60N/120N per meter. The newtons cancel out and you get a final answer of Δx = 0.5 meters
