We begin by noting that the angle of incidence is the one that's taken with respect to the normal to the surface in question. In this case the angle of incidence is 30. The material is Flint Glass according to the original question. The refractive indez of air n1=1, the refractive index of red in flint glass is nred=1.57, finally for violet in the glass medium is nviolet=1.60. Snell's Law dictates:

Where 

 differs for each wavelenght, that means violet and red will have different refractive indices in the glass.
In the second figure provided details are given on which are the angles in question, 

 is the distance between both rays.


At what distance d from the incidence normal will the beams land at the bottom?
For violet we have:

For red we have:

We finally have:
 
 
        
        
        
Answer:
The heat capacity for the second process is 15 J/K.
Explanation:
Given that,
Work = 100 J
Change temperature = 5 k
For adiabatic process,
The heat energy always same.


We need to calculate the number of moles and specific heat 
Using formula of heat


Put the value into the formula


We need to calculate the heat 
Using formula of heat

Put the value into the formula


We need to calculate the heat capacity for the second process
Using formula of heat

Put the value into the formula



Hence, The heat capacity for the second process is 15 J/K.
 
        
             
        
        
        
It would take about 2 thirds of a second or .66666666 repeating of a second. please give brainliest?
        
             
        
        
        
Answer:
The amount of time for the whole journey is 8 hours.
Explanation:
A truck covered 2/7 of a journey at an average speed of 40  mph. Representing 1 the total of the trip traveled, then the rest of the distance traveled is calculated as: 
So if the truck covered the remaining 200 miles at  , this means that
, this means that  of the trip represents the 200 miles. So, to calculate the total distance traveled by the truck, you apply the following rule of three: if
 of the trip represents the 200 miles. So, to calculate the total distance traveled by the truck, you apply the following rule of three: if  of the route represents 200 miles, the integer 1 (which represents the total of the route), how many miles are they?
 of the route represents 200 miles, the integer 1 (which represents the total of the route), how many miles are they?

miles= 280 
So the total distance traveled is 280 miles. Since speed is the relationship between the space traveled by an object and the time used for it ( ), then if the average of the entire trip was 35 mph and the distance traveled 280 miles, the time is calculated as:
), then if the average of the entire trip was 35 mph and the distance traveled 280 miles, the time is calculated as:

time= 8 h
