The indices of refraction for red, green, and violet light in glass are nred =1.520, ngreen = 1.526, and nviolet = 1.538. When a ray of light passes through a transparent slab of glass, the emergent ray is parallel to the incident ray, but can be displaced relative to it. For light passing through a glass slab that is surrounded by air, which color is displaced the most?(a) All colors are displaced equally.
(b) Red
(c) Green
(d) Violet
Answers
The color which is displaced the most will be "Violet".
Refractive index
According to the question,
Indices of refraction,
Red, = 1.520
Green, = 1.526
Violet, = 1.538
The higher the refractive index of something like a wavelength, the generally greater the departure from the glass's surfaces or ground. The emerging ray always seems to be perpendicular towards the incident light.
You now understand something the greater more deviation somewhere at this same surface of the object, the greater the laterally or sideways displacement.
Thus the response above i.e., "Option d" is correct.

Answer:
(d) Violet
Explanation:
The formula for lateral displacement = t sin ( i - r ) / cos r
where t is thickness of slab , i is angle of incidence , r is angle of refraction
refractive index = sin i / sin r
if refractive index is high , for given i , angle of r will be less
i - r will be more , hence sin( i - r ) will be more
cos r will be less ( larger the angle , lesser will be its cos value )
sin( i - r ) / cos r will be more
lateral displacement will be more .
hence higher refractive index results into greater displacement .
So violet ray will undergo maximum displacement .

Answers
Answer: A. The flask would probably feel cooler than before the reaction started.
Explanation: An endothermic reaction is a type of of chemical reaction in which energy is absorbed from the surroundings. The temperature of the surrounding decreases.
An Exothermic reaction is a type of of chemical reaction in which energy is released into the surrounding. The temperature of the surrounding increases.
When an endothermic reaction takes place in the flask, the heat is absorbed by the flask and thus the temperature of the surrounding (here the flask) will decrease which can be felt by touching the outside of the test tube. Thus the flask would appear colder.

The answer is 3 tonnes, because 3 tonnes equal 6613.87 pounds, which is higher than 6001.
I hope this helps! I would love it if you could help me answer my question too!
Final answer:
6001 pounds is slightly more than 3 tons. This is because, in the comparison scale, 1 ton is equal to 2000 pounds. So, 3 tons equals 6000 pounds.
Explanation:
The student is asking which is more, 3 tons or 6001 pounds. To determine this, we need to understand the relationship between tons and pounds. We know that 1 ton is equivalent to 2000 pounds. So, 3 tons would be equivalent to 3*2000 = 6000 pounds.
Hence, comparing 6001 pounds with 3 tons, or effectively 6000 pounds, 6001 pounds is slightly more than 3 tons.

Answer: The correct answer is option D.
Explanation:
At point B, the temperature becomes constant which means that energy given to the substance is getting used in to the breaking of forces which are present in between the molecules of the substance. These forces are known as inter-molecular forces. Or we can also say that ,at point B the state of the substance is changing.
Hence, the correct answer is option D.

Explanation:
Notice that nothing but the mass and height are given, and the mass is not really necessary. It will cancel when we do the problem.
So the potential energy at the top equals the Kinetic energy at the bottom.
PE_top = Ke_bottom
mgh = 1/2 m v^2 Divide by m
mgh/m =1/2 mv^2/m
gh = 1/2 v^2 Multiply both sides by 2
