Answer:
You just answer questions or ask one for other people to answer
If you put a answer that doesn't have to do with the question you will get reported then youwill get a warning get to many warnings and you will be banned
Answer:
D. is greater for turbulent flow than for laminar flow
Explanation:
what is friction drag?
- friction drag is a phenomenon experienced when a body moves through a fluid. A practical example can be seen in the mild warmth we experience rubbing the palm's of one's hand together only in this case we are dealing with a solid body and a fluid (e.g air, water). friction drag is directly proportional to the area of the surface in contact with the fluid and increases as velocity increases. We see a practical example of this when the rate at which one rubs the palms together is fast but we use the word turbulent when we are dealing with fluids. Turbulent flow creates more friction drag than laminar flow( Flow between a smooth body and fluid) due to its greater interaction with the surface of the body
- it is important to know that friction is also called viscous drag or skin drag
- I recommend Richardson and coulson vol 2 textbook, page 149, Chemical enginering fluid mechanics textbook by Ron dardy, page 341 for clearer explanation
Jogger moves in three displacements
d1 = 10 blocks East
d2 = 5 blocks South
d3 = 2 blocks East
now we can say
total displacement towards East direction will be
Total displacement towards South
now to find the net displacement we can use vector addition
<em>so magnitude of net displacement will be equal to 13 blocks</em>
Answer:
The answer to your question is Power = 24 Watts
Explanation:
Data
time = 3 s
Work = 72 J
Power = ?
Power is defined as the rate at which a work is done.
Formula
Power = Work / time
-Substitution
Power = 72/3
-Simplification
Power = 24 Watts
-Conclusion
The Power exerts by 72 J of work in 3 seconds is 24 watts.
