length of night increases, and change to night from day and viceversa would occur quite suddenly as there will be no atmosphere to cause diffraction as well scattering light rays.

A prism has two inclined surfaces, so even if you the light is incident perpendicular to the first surface, it will bend while emerging from the second. (mudna toh hai hi)

dw:1334821169427:dw ab ek aur image hoga shaayad, main soch nahi paa raha abhi, bata hoon ek minute ruko. The difference between refraction for monochromatic and polychromatic light is only this that polychromatic light is made up of more than one wavelengths of light. Now, for different wavelengths, relative refractive index is different, toh bending kisi mein kam kisi mein zyada hogi.(jaise color spectrum mein hota hai) @Ishaan94 explanation for why days would get shorter is that, when the earth then while rotating, when a certain longitude of it is just about to lose direct reception of sun rays, would suddenly get dark. BUT, in the present case, due to atmosphere (OOPS i forgot to mention the most important phenomena here  REFRACTION), light rays bend, and reach that portion of the earth for just a few more minutes than they would have. This elongates the daylight period.

dw:1334822038038:dw Now in this question, there is no net force on the block due to the movement of the elevator, since it is moving with a constant velocity. But the lift moves up by 2m in that once second, and the block also moves by 2metres (since there is no net motion on the incline)

Hmm, @Aadarsh continuing with the liftquestion. So, the block moves up by 2m. And the force of friction is acting at an angle of 45 degrees with the displacement. Its magnitude is (mu *mg * cos45) = mg*sin45 (since the FBD shows that the gravitational force along the incline is being balanced by the frictinal force, causing the block to remain at rest w.r.t. the incline) So work done by friction = = W = F.s.cos(x) ...here F = frictional force's magnitude, s=displacement, x= angle between the direction of the force that is acting and the displacement = 45 degrees S0, W = mgsin45 * s * cos 45 = 10/sqrt2 * 2 * 1/sqrt2 = 10 J.
