Textbook Question
Chapter 7.4, Problem 5CC
In January 2008, Scientific American reported that physicists Peter Sutter and Eli Sutter of Brookhaven National Laboratories made a pipette to measure droplets in units of a zeptoliter [zl ]. Previously, the smallest unit of measure in a pipette was an attoliter [al]. Convert the measurement of 5 zeptoliters [zl] into units of picoliters [pl].

On an alien planet, the law that expresses the flow of blood through a blood vessel, F, as a function of the radius r of the vessel is
f=kr5/2where k is a constant.
Certain geological features of this planet produce a gas that changes the radius of blood vessels by 5% at the time of inhalation. What would the corresponding increase in blood flow through the vessel at this time be?

- In the movie Back to the Future, Marty travels back in time to 1955. In 1955, the only available light bulbs in the United States were incandescent bulbs. Assume that last year, you traveled back in time to 1955 and changed all the light bulbs in a single average American household (45 light bulbs) from 75-watt incandescent bulbs to the corresponding 17-watt LED bulbs. The estimated usage is 3 hours per day , at a cost of $0.11 per kilowatt-hour . Based on energy cost alone - not considering the cost to replace any light bulbs and not considering any changes in energy cost with time - how much money in dollars would this household have saved over a 66-year time span (from 1955 to 2021) by changing from incandescent to LED bulbs?arrow_forwardWrite and take a picture of your answer with complete solution on a piece of paper and attach the picture.
