12. A year on any planet is the number of days it takes for the planet to complete one orbit around the Sun. It takes 365 days for Earth. It takes 365 days for the
Earth to revolve around the Sun, so on Earth a year is 365 days. How old are
you in Mars-years?

Step 1: Calculate how many Earth days old you are.

Step 2: Divide that number the number of days it takes Mars to complete an orbit.

Step 3: Explain your answer

Well, 365 days is about how long it takes for Earth to orbit all the way around the Sun one time. It's not exactly this simple though. An Earth year is actually about 365 days, plus approximately 6 hours.

the potential energy of the reactants is 200j.

from the energy diagram, the energy of the product formed is 350j; this means that, this reaction is an endothermic reaction, because it absorbs energy from its environment.

a rain shadow is a dry region of land on the side that is protected against the prevailing winds of a mountain range. the prevailing winds are the winds that occur most of the time in a particular place of the earth

prevailing winds carry air toward the mountain range. as the air rises up over a mountain range, the air cools, water vapor condenses, and clouds form. on this side of the mountains, called the windward side, precipitation falls in the form of  rain  or snow. this dry air produces a  rain shadow.
