The Pathway
• air enters the nostrils
•passes through the nasopharynx
•the oral pharynx
•through the glottis
• into the trachea
• into the right and left bronchi, with branches and rebranches into
• bronchioles each of which terminates in a cluster
• alveoli
The correct answer is "All of the above are correct"
Answer:
1250Joules
Explanation:
The parameters given are:
Force=5,000N
Distance= 0.25m
Work done by the Jack=
force×distance
= 5,000×0.25
=1250joules
Therefore, the Workdone by the Jack is 1250Joules
