Answer:
N = 195 turns
Explanation:
The inductance of the inductor, L = 500 μH = 500 * 10⁻⁶H
The length of the tube, l = 12 cm = 0.12 m
The diameter of the tube, d = 4 cm = 0.04 m
Radius, r = 0.04/2 = 0.02 m
Area of the tube, A = πr² = 0.02²π = 0.0004π m²

The inductance of a solenoid is given by:


The answer would be 20000
The answer in standard form/scientific notation would be 2 x 10^4
(The exponent is 4 because that's how many digits after the 2 there is)
I calculated on a sheet and used differentiation to solve the problems.
Answer:
x=0.8
Explanation:
Defining our values we have

Where
is the pressure of the super heated steam
is the Temperature of the super heated steam
and
is the pressure in an adiabatic process.
State 1

State 2

Note that here in state 2 the process is Reversible.
At the value where
we have

Through this values we can calculate the Fraction of steam,
