Math is the process of using the given information, along with
all the general stuff that you know, to find the missing information.
With no given information, we have no way to even guess at
an answer.
Answer:
Angle of refraction for red light is
Angle of refraction for blue light is
Explanation:
It is given refractive index for red light is 
Refractive index of blue light 
Angle of incidence 
According to law of refraction 
For red light 



Therefore angle of refraction for red light is 
Similarly for blue light 


r = 
Therefore angle of refraction for blue light is 
The answer is
6.67 Ohms (I tried to find the ohms sign but it looks like the lululemon logo)
Q.1
Answer . Momentum = mass x velocity
Momentum/mass = velocity
5/0.8 = velocity
6.25 m/s = velocity
Q.2
Answer . F = ma => a = f/m => a = 7/3.2 => a = 2.1875m/s²
