Answer:
The epithelial cell shape and stratification are related to its function. For example, the skin is specialized to act as a "physical" barrier to the outside world. This barrier is both structural (multi-layered) and chemical in nature. Another example is the cells that make up the tubular elements of the kidney.
Explanation:
Answer:
momentum=mass x velocity= 10 x 2 = 20kgm/s
Rate of work or Power done by the student can be computed with below formulas.
1. Formula for Work
Work = Force x distance
Force or F = Force applied to the object
distance or d = displacement
2. Formula for Power
P = Work done / Time it was done or completed
Substituting the values we have,
Work or Work done = 150 N x 35 meters = 5250 J (unit of work).
Lastly computing for the rate we have,
Power or rate of work = 5250 J / 300 seconds (or 5 min) = 17.5 Joule/S or Watts
Answer is 17.5 watts
