c. 50% is absorbed by the atmosphere
d. 80% is absorbed by land and oceans
b.
700

magnified images possible images can be real = projected onto a screen

this could be newton#'s law of cooling. the cooling curve is exponential

305.7

explanation:

density =m/v

density =917/3.00

density = 305.

approximately = 305.7

in four significant figures

+15-35=-20

going in opposite directions
