The answer is B
I used these equations then i putted it together.
Charge = number of ( electron or proton ) x charge of ( electron or proton )
Force = k x (q1 q2)/r²
Alcohol use causes to reduced inhibitions that which it may be lead to mistakes in judgment with other drugs, sex, driving, and violent. When everyone drink alcohol it is bad for everyone it is for adults only ask to permission to do that.
n₂ = index of refraction of glass = 1.58
n₁ = index of refraction of air = 1
θ = Brewster's angle
Brewster's angle is that incident angle at which the the reflected light from the interface of two medium is completely polarized.
Brewster's angle is given as
θ = tan⁻¹(n₂ /n₁ )
θ = tan⁻¹(1.58/1 )
θ = 57.7 deg
hence the Brewster's angle comes out to be 57.7 deg
Answer: discplacement/change in time = average velocity.
Explanation:
There is a formula for velocity which is given above
