Physics: light "a red laser beam travels from flint glass into lemon oil. the angle of incidence is 40* while the angle of refraction is 44.4* what is the refractive index of lemon oil? " i know the refractive index of flint glass is 1.61, but i need finding the equation to use to find the refractive index of lemon oil.

the displacement produced by the body.  

the amount of force subjected to the body.  

the angle between the direction of force and displacement

im guessing the west of station b

electrical potential energy =0.072 j

explanation:

electrical potential energy is given by

u= q δv

q= charge=6 c

δv= potential difference and is given by

δv= e d

e= electric field

d= distance=5 mm=0.005 m

δv=2.4 (0.005)=0.012 v

now electric potential energy= u= q δv

u=6 (0.012)

u=0.072 j
