Question

the density of body fat is 0.9g/cm 26. Rank the following lengths from smallest to greatest: (a) 1 mum (b) 1000 nm; (e) 100000 pm; (d) 0.01 cm; (e) 0.0000000001 km. 27. Rank these speed measurements from smallest to greatest: (a) 55 mi/h; (b) 82 km/h; (e) 33 m/s; (d) 3.0 cm/ms; (e) 1.0 mi/mm. 28. The density of body fat is 0.9 g/cm^3. Find the density in kg/m^3. A cell membrane is 7.0 nm thick. How thick is it in inches? The label on a small soda bottle lists the volume of the drink as 355 mL. (a) How many fluid ounces are in the bottle? A competitor?s drink is labeled 16.0 fl oz. (b) How many milliliters are in that drink?

Explanation / Answer

26) c < e < a = b < d

a) 1 micro m = 1*10^-6 m

b) 1000 nm = 1*10^-6 m

c) 100000 pm = 1*10^-8 m

d) 0.01 cm = 1*10^-4 m

e) 0.0000000001 km = 1*10^-7 m

27) b < a < e < d < e

a) 55 mi/h = 55*1.609*5/18 = 24.58 m/s

b) 82 km/h = 82*5/18 = 22.78

c) 33m/s

d) 3 cm/ms = 30 m/s

e) 1*1609/60 = 26.82 m/s

28) 0.9 g/cm^3 = 0.9*10^-3 kg/(10^-2*m)^3

= 900 kg/m^3
