Referring only to Table 1.2 , answer the following questions: a . Devices are available that allow liquid volumes as small as one microliter ( μL ) to be measured. How many microliters would be contained in 1.00 liter ? b . Electrical power is often measured in kilowatts. How many watts would equal 75 kilowatts ? c . Ultrasound is sound of such high frequency that it cannot be heard. The frequency is measured in hertz (vibrations per second). How many hertz correspond to 15 megahertz ? d . A chlorine atom has a diameter of 200 picometers . How many meters is this diameter?

1. A friend claims that a metric ton is more than twice the mass of an English ton because a
kilogram is more than twice the mass of a pound. Make a quantitative argument in support of or
against your friend's claim. (1 page)
2. Upgraded U.S. fuel economy standards formalized in 2012 call for a 54.5 mile-per-galloon
average for new cars and light trucks in 2025. A politician opposing this increase claims it will
save "only a drop in the bucket" compared with the 2014 fleet average of about 23 mpg.
Formulate a counterargument showing that the increase - once the entire fleet reaches 54.5 mpg
- consumption rate from its 2014 value of about 375 million gallons per day. State any additional
assumptions you make.
