You have no answers down for me to help but here is the answer Synapse
jot down the answers next time lol
Air would go through the trachea, then the bronchi, the bronchioles, and then the alveoli.
Experiment , because a law is after a certain thing is well studied and now they could make conclusions. An example would be something like observing a wart and then experimenting what could work to cure the wart .
Explanation:
Let the spring constant of two springs are k₁ and k₂. In series combination of springs, the equivalent of springs is given by :

So, if it is required to swap out a single spring for the two springs that are in series, the spring constant need to be to generate the same force at any displacement is,

Hence, this is the required solution.
