Check Your Understanding Figure 1.4 says the mass of the atmosphere is 1019kg . Assuming the density of the atmosphere is 1kg/m3 , estimate the height of Earth’s atmosphere. Do you think your answer is an underestimate or an overestimate? Explain why. How many piano tuners are there in New York City? How many leaves are on that tree? If you are studying photosynthesis or thinking of writing a smartphone app tot piano tuners, then the answers to these questions might be of great interest to you. Otherwise, you probably couldn’t care less what the answers are. However, these are exactly the soils of estimation problems that people in various tech industries have been asking potential employees to evaluate their quantitative reasoning skills. If building physical intuition and evaluating quantitative claims do not seem like sufficient reasons tot you to practice estimation problems, how about the fact that being good at them just might land you a high-paying job?

Assume it takes 10.0 min to fill a 35.0-gal gasoline tank. (1 U.S. gal = 231 in.3) Determine the time interval, in hours, required to fill a 1.00-m3 volume at the same rate. (1 U.S. gal = 231 in.3)
Under the conditions of normal activity, an adult inhales about 1 L of air during each inhalation. With the aid of a watch, determine the time for one of your own inhalations by timing several breaths and dividing the total length by the number of breaths. calculate the average air speedin meters per second through your trachea during eachinhalation. The radius of the trachea in adult humans isapproximately 10−2 m . From the data above, calculate theReynolds number for the air flow in the trachea duringinhalation. Do you expect the air flow to be laminar or turbulent?

this is quite hard to slve
Ans all
The answer to (a) is -ve but (b) isn't correct wether +ive or -ive. I'm not understanding (b).
