A test on Unit Conversions is scheduled on Monday September 27. The following are some problems that are quite difficult.
Review Problems:
1. A crazy Klingon warrior eats 50 strips of dog meat for breakfast. Each dog can produce 34 strips of meat. Each strip weights 5g.
a. How many kilograms of meat do four crazy Klingon's eat for breakfast in one week?
4 klingon x 50 strips of dog meat = 200 strips/day
5 g x 200 strips = 1000g/day
1000g x 7 days = 7000g = 7kg
b. How many dogs get eaten by one Klingon per week?
50 strips of dog meat x 7 days = 350 strips of dog meat
350 strips of dog meat x 1 dog / 34 strips of meat = 10.29411765 (Round up) = 10.3 dogs
2. Convert 28.4 g/mL into kilograms per litre
28.4 g/1 ml x 1 kg/10^3 g x .001 ml/1 L=28.4 kg/L
3. Convert 872 cm ^3 into cubic meters.
872 cm^2 x 1 m^3/10^6cm^3=872 x 10^-6m^3=8.72 x 10^-4 m^3
4. (1234 km/1 hr) x (1 hr/3600 s) x (1 s/.001 ms) x (10^3 m/1 km) x (10^2 cm/1 m) = 34.3 cm/ms = 3.43 x 10^1 cm/ms
