1) In 20 seconds of freefall, an object will travel approximately 1.96 kilometers. What is this value expressed in centimeters, and written in scientific notation? 2) Convert 365 micrograms to grams. 3) A mineral called iron pyrite forms crystals that are shaped like rectangular boxes. One such crystal is 8.6 ∗ 10^(− 3) meters tall, 5.0 ∗ 10^(− 2) meters wide, and 7.8 ∗ 10^ (− 2) meters deep. Ignoring significant figures, what is the volume of this rectangular crystal? Please answer once you can, thank you.
