The document discusses scientific notation and conversions between units of measurement. It provides the diameter of a water molecule, the distance to the Hubble Deep Field in light years, and the conversion of a light year to meters. It then poses two calculation problems - to determine the number of water molecules that can fit in a bucket, and to convert the distance to the Hubble Deep Field from light years to meters.

5. I know that the diameter of a water molecule is 2.8 x 10-10 meters.
I also know that the radius of the bucket is 0.25 meters and the
height is .5 meters. How many water molecules can you fit in one
bucket the volume of a water molecule
First find
Then find the volume of the bucket
finally divide the volume of the bucket by the volume of a water
molecule.

6. The deep hubble field is 12.7 billion light years away. A light year is
equal to 9.46 x 1015 Meters. How far away is the deep hubble field
in meters?
First write the distance to the Hubble deep field in scientific notation
solve for meters with the conversion factor.
