48. GO The diffusion constant for the amino acid glycine in water has a value of 1.06 X 10-º m²/s. In a 2.0-cm-long tube with a cross-sectional area of 1.5 × 10-“ m², the mass rate of diffusion is mlt = 4.2 × 10-1ª kg/s, because the glycine concentration is maintained at a value of 8.3 × 10-³ kg/m³ at one end of the tube and at a lower value at the other end. What is the lower concentration?

How many cubic meters of helium are required to lift a light balloon with a 400-kg payload to a height of 8 000 m? Take Hc = 0.179 kg/m3. Assume the balloon maintains a constant volume and the density of air decreases with the altitude z according to the expression pair = 0e-z/8 000, where z is in meters and 0 = 1.20 kg/m3 is the density of air at sea level.
The average human has a density of 945 kg/m3 after in haling and 1 020 kg/m3 after exhaling.

(b) Given that bone and muscle are denser than fat, what physical characteristics differentiate sinkers (those who tend to sink in water) from floaters (those who readily float)?
An airtight dispenser for drinking water is 25 cm × 10 cm in horizontal dimensions and 20 cm tall. It has a tap of negligible volume that opens at the level of the bottom of the dispenser. Initially, it contains Water to a level 3.0 cm from the top and air at the ambient pressure, 1.00 atm, from there to the top. When the tap is opened, water will flow out until the gauge pressure at the bottom of dispenser, and thus at the opening of the tap, is 0. What volume of water flows out? Assume the temperature is constant, the dispenser is perfectly rigid, and the water has a constant density of 1000 kg/m3.
