Question

(C) The Earth completes this in 365 and 1/4th days.
(d) This is formed when the path of light rays is blocked by an opaque object.
(e) Objects of this material do not form black shadow.​

Answer 1

Answer:

C Why Do We Have Leap Years? A year is defined as the time it takes for the Earth to orbit around the sun once. It takes the Earth about 365 1/4 days to make one entire orbit around the sun (a day is one rotation around the Earth's axis).

D Answer: Shadows are formed when the path of light rays is obstructed by something opaque. If light rays can bend around an object that means they will pass around the object and the path of the light rays will not be obstructed.

E Transparent objects cannot form a shadow. They are only formed in opaque or translucent objects. If we take a glass slab, no shadow is formed because it allows light to pass through it.
