- Additional
questions
- AQ 1: At CDN$1.20/L for gasoline [L = litres], how
much (in US$) will it cost to drive from Windsor, Ontario, to North
Manchester, IN, in a Honda Civic Hybrid which gets 50 mi/gal on the
highway? What is the cost per gallon in USD? Use the web
to get any additional info you need!
www.x-rates.com is a good place
for currency exchange rates. [CDN$ is Canadian dollars; USD$
is U.S. dollars)]
- AQ 2: U.S. “proved” oil reserves are estimated to be about 32.3 billion bbl (bbl = barrels). How long will these reserves last at our current consumption rate of about 35.9 QBtu/year (2016)?
[Note: 1 bbl crude oil = 5.8 x 10^{6} Btu
]
- Extra Credit: One litre of red dye molecules is dumped in the
ocean from a bottle. The ocean is given a really good stir and one
litre of the well-mixed seawater is scooped up in the bottle. About
how many dye molecules will now be in the bottle?
HW 1 - Due Friday, 01 Sep 2017
- Read: 1.1 – 1.5; 1.8
- Q: 1.2
- P:
1.24, 1.25
- AQ1: Write these numbers in scientific notation:
- A. 0.000000000000001 m (roughly the size of a small atomic nucleus)
- B. 98,000,000,000,000,000 Btu (approximate total US energy consumption in 2010)
