Answer:

Explanation:
magnification is the ratio of distance of image to distance of object
i.e. 

As per the lens equation,

We will calculate the focal length of the mirror

Now for convex mirror only the sign will change
Thus, focal length would be equal to

Plugging this value into lens equation, we get

Answer:
D.
Explanation:

The name for continents in one landmass surrounded by gigantic ocean is Pangaea.
This name is originated from the Greek words Pan ("all") and Gaia ("Earth"). It describes the supercontinent that would have existed in the Cenozoic and Mesozoic periods by the joining of all continents that we know them today.
The gigantic ocean that surrounded it is called Panthalassa, from Greek Pan ("all") and thálassa ("sea").
Have a nice day!
