How do i set this up using the dimensional analysis method

You want to start with years and end with kilograms of dog food.

1 yr → kg dog food

The sequence must be

1 yr → days → cups of food → grams of food → kilograms of food

At each step, you use a conversion factor (CF) to get the result you want.

Each CF must have

•on top the units of the result you want

•on the bottom, the units of the preceding term

Your sequence now becomes

Time = 1 yr × (no. of days/yr) × (no. of cups/day) × (g dog food/cup)

× (kg dog food/g dog food) = kg dog food

Notice that the denominator of a CF always cancels the units of the one before it.

Do you get something like 100 kg dog food?

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.
