A ray of laser light travels through air and enters an unknown material. The laser enters the material at an angle of 36 degrees
V125BC [204]

Answer:1.27

Explanation:

Given

incident angle i=36^{\circ}

refracted angle r=27.5^{\circ}

Suppose n_2 is the refractive index of material then using Snell's law we  can write

n_1\sin i=n_2\sin r

where n_1=refractive index of air

1\times \sin (36)=n_2\times \sin (27.5)

n_2=\dfrac{0.5877}{0.4617}

n_2=1.27

Q12. How much force is applied on the body when 150 joule of work
ra1l [238]

Force = Work/distance

Force = 150/10

          =  15 Newtons

Force = 15 Newtons

Therefore, 15 newtons of force is applied to the body when 150 joules of work

is done in displacing the body through a distance of 10m in the  direction of the force.
