The tundra because it's growing season is too short.
<h2>Answer:</h2>
0
<h2>Explanation:</h2>
Since the current carrying wire is placed along the axis of the cylinder, according to the right hand rule, the magnetic field will be tangent to the surface of the cylinder. Therefore, there is no magnetic field through the cylinder.
Remember that the magnetic flux through a given area is the total magnetic field passing through that area. Since there is not magnetic field through the cylinder, the total magnetic flux is therefore zero (0).
Your experiment should keep one thing constant and measure the other. So vary the temp and measure the pressure. You will get a set of data that relates pressure with temp.

So
P and T are directly proportional.

Answer:
(a) 
(b) 
: From the air to the surroundings.
Explanation:
Hello,
(a) In this case, we can compute the area at the entrance by firstly computing the inlet volumetric flow:
Then, with the velocity, we compute the area:
(b) In this case, via the following energy balance for the nozzle:
We can easily compute the change in the enthalpy by using the given Cp and neglecting the work (no done work):
Finally, the heat turns out:
![Q=-348.795kW+\frac{1}{2}*2.3\frac{kg}{s}*[(460\frac{m}{s})^2 -(3\frac{m}{s})^2 ]\\\\Q=-348.795kW+243329.65W*\frac{1kW}{1000W}\\ \\Q=-105.5kW](https://tex.z-dn.net/?f=Q%3D-348.795kW%2B%5Cfrac%7B1%7D%7B2%7D%2A2.3%5Cfrac%7Bkg%7D%7Bs%7D%2A%5B%28460%5Cfrac%7Bm%7D%7Bs%7D%29%5E2%20%20%20-%283%5Cfrac%7Bm%7D%7Bs%7D%29%5E2%20%20%5D%5C%5C%5C%5CQ%3D-348.795kW%2B243329.65W%2A%5Cfrac%7B1kW%7D%7B1000W%7D%5C%5C%20%5C%5CQ%3D-105.5kW)
Such sign, means the heat is being transferred from the air to the surroundings.
