The tank pressure is 5.08 kPa and the mass flow rate is 2.6 kg/s.
The given parameters:
- <em>Throat area of the nozzle, </em>
<em> = 10 cm² = 0.001 m²</em> - <em>The exit area of the nozzle, A = 28.96 cm² = 0.002896 m²</em>
- <em>Air pressure at sea level = 101.325 kPa</em>
The ratio of the areas of the converging-diverging nozzle is calculated as follows;

From supersonic isentropic table, at
, we can determine the following;

The tank pressure is calculated as follows;

Thus, the tank pressure is 5.08 kPa and the mass flow rate is 2.6 kg/s.

In the above case we can say that power given by external agent to pull the rod must be equal to the power dissipated in the form of heat due to magnetic induction.
Part a)
when we pull the rod with constant speed then power required will be product of force and velocity
here we will have

P = 4 W
v = 4 m/s
now we will have


So external force required will be 1 N
PART B)
now in order to find magnetic field strength we can say

here we know that induced EMF in the wire is E = vBL
so power due to induced magnetic field is given by


by solving above equation we will have

Rust is not because it does not occur through a chemical process
Answer:
Earth's atmosphere is a layer of gases surrounding the planet Earth and retained by the Earth's gravity. It contains roughly 78% nitrogen and 21% oxygen 0.97% argon and carbon dioxide 0.04% trace amounts of other gases, and water vapor. This mixture of gases is commonly known as air. Explanation:

It's actually a deceleration. You should get a negative answer because the ball is slowing down.
Givens
vi = 8.09 m/s
vf = 5.87 m/s
t = 9.17
Formula
a = (vf - vi) /t Substitute the givens into the formula
Solution
a = (5.87 - 8.09)/9.17
Answer
a = - 2.22 m/s^2
