Answer:
refractive index for water,glass,diamond are 0.752m, 0.667m, 0.413m respectively
Explanation:
refractive index (n) = 
velocity =
The time for travel is kept constant for all mediums.
refractive index (n) = 
distance in medium = 

For water, n= 1.33


For glass, n=1.5


For diamond, n= 2.42


Answer:
Circuit 1 and Circuit 3
Explanation:
If there is 1 Circuit and it runs out of energy, there's another one to produce the power.
Force on the particle is defined as the application of the force field of one particle on another particle. The magnitude and direction of the electrical force will be 4.05×10⁴N towards the north.
<h3>What is electrical force?</h3>
Force on the particle is defined as the application of the force field of one particle on another particle. It is a type of virtual force.
The given data in the problem is
q₁ is the negative charge = 6 µC=6×10⁻⁶ C
q₂ is the positive charge = 3 µC=3×10⁻⁶ C
r is the distance between the charges=0.002 m
is the electric force =?
The value of electric force will be;

Hence the magnitude and direction of the electrical force will be 4.05×10⁴N towards the north.

Here is the formula that you need to know for this problem:
Number of proton (atomic number) + Number of neutrons = Mass number
So,
45 + Number of Neutrons = 161
Number of neutrons = 161 - 45
Number of Neutrons = 116
"It acts over a very small distance" would be the best answer as to a characteristic of the strong nuclear force, since its primary purpose is to bind the smallest particles together.
