The picture below shows the eastern sky. The Sun is shown in four different places. At different times in one day, the Sun will be in each of those places.

Which position will the Sun be closest to at noon?

i look it up online and i'll tell you

the density(ratio between mass and volume as m/v) decreases from top to bottom in periodic table group as the size increases and nuclear charge decreases. but in periods density increases from left to right as atom size decreases and nuclear charge increases.
