The total weight of the box shown in the diagram above can be measured by placing a scale at a and another at b and adding the weights shown two scales.
which of the following would be the most accurate method of measuring the weight of a heavy four wheel cargo truck using only one heavy duty scale

a is the answer to this question

explanation:

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.

it forms an anion that has a larger radius. anions have a negative charge and are larger than the original atom.
