)light strikes a 5.0-cm thick sheet of glass at an angle of incidence in air of 50°. the sheet has parallel faces and the glass has an index of refraction 1.50. (a) what is the angle of refraction in the glass? (b) after traveling through the glass the light re-emerges into the air. what is the final angle of refraction in air? (c) as it leaves the glass, by what distance is the path of the ray is displaced from what it was before entering the glass?

answer; (d) spontaneous processes are characterized by the overall conversion of order to disorder;

there are no correct statementd on the list of choices you provided.

one "light year" is the distance that light travels, through vacuum, in one julian year.   that's 365.25 days, of 24 hours each.

explanation:

to push or pull an object in a certain direction is known as force. a force in moving an object from one place to another.

force depends on the mass of an object. so, more is the mass of an object more will be the force required to move the object.

thus, we can conclude that the use of force to move an object is push or pull.
