Given;
redistivity =1.68/100000000W.m
diameter =0.40in
=0.01016m
length =1m
resistance =?
redistivity =resistance×area/lenght
restance=resistivity × length /area
so, resistance =1.6535/1000000 ohmn
Answer:
Explanation:
The Bernoulli equation is:
(1)
- P is pressure related to the fluid
- ρ is the density of the fluid (ρ(air)=1.23 kg/m³)
- v is the speed of the fluid
- h is the displacement from one position to the other
Now let's apply the equation (1), for our case:
(2)
here we assume that h is the same in both cases so it canceled out.
- <u>subscript 1</u> is related to the upper surface of the wings
- <u>subscript 2</u> is related to the low surface of the wings
Solving the equation for v₁ we have:
(3)
Now, we know that pressure P=F/A (force over area)
(4)
Combining (3) and (4), we can find v1.
I hope it helps you!
No because a solution is already a solution
Answer:
I think it's C
Explanation:
C which is oxygen all the rest are greenhouse gases, but I don't think oxygen itself is one
