In Astronomy we often deal with distances, or lengths, that range form the very small to the very large. For instance The size of a nucleus is roughly 0.000, 000,000,000,001 meters and the distance to the nearest star is roughly 700,000,000,000 meters. We will talk about these numbers using scientific notation where each zero is counted as ten raised to an exponent equal to the number of zeros. Le the size of a nucleus is 1 x...
