Single stranded wires are best suited for products that won't encounter much movement;this type of wiring is often only used in smaller gauge wiring applications as it can be difficult to maneuver and utilize a heavy gauge, single conductor wire.

Katena32 [7]

Answer:

) You must create a Low Pass Filter for an audio amplifier. You must pass 10khz and block

60khz. In designing this, you must choose a cutoff frequency exactly half way between

these two frequencies. In addition, you must use a 0.2uF capacitor in you LPF circuit.

Given these criteria, analyze this circuit, and determine the necessary resistor value in

Ohms. Find the output Voltage at both ends of the spectrum. Based on your results, is

this a good design? NOTE: You MUST show your work (when using MS Word, choose

“Insert”--- “Equation”). (6 marks)

a. Solve for fc

b. Solve for R

c. Solve for Vout at 10khz

d. Solve for Vout at 60khz

e. Good design> (yes or no with an explanation)

A well-insulated rigid tank contains 5 kg of a saturated liquid–vapor mixture of water at 200 kPa. Initially, three-quarters of

vlabodo [156]

Answer:

$S_{gen} = 18.519\,\frac{kJ}{K}$

Explanation:

Given that rigid tank is a closed system, the following model is constructed after the First Law of Thermodynamics:

$W_{heater} + U_{sys,1} - U_{sys,2} = 0$

$W_{heater} = U_{sys,2} - U_{sys,1}$

$W_{heater} = m\cdot (u_{2}-u_{1})$

The entropy generation inside the rigid tank is determined by appropriate application of the Second Law of Thermodynamics:

$S_{sys,1} - S_{sys,2} + S_{gen} = 0$

$S_{gen} = S_{sys,2} - S_{sys,1}$

$S_{gen} = m\cdot (s_{2}-s_{1})$

The properties of the steam are obtained from steam tables:

Intial State

$P = 200\,kPa$

$T = 120.21\,^{\textdegree}C$

$\nu = 0.2222\,\frac{m^{3}}{kg}$

$u = 1010.7\,\frac{kJ}{kg}$

$s = 2.9294\,\frac{kJ}{kg\cdot K}$

$x = 0.25$

Final State

$P = 869.567\,kPa$

$T = 173.88\,^{\textdegree} C$

$\nu = 0.2222\,\frac{m^{3}}{kg}$

$u = 2578.6\,\frac{kJ}{kg}$

$s = 6.6332\,\frac{kJ}{kg\cdot K}$

$x = 1.00$

The entropy change of the steam during the process is:

$S_{gen} = (5\,kg)\cdot \left(6.6332\,\frac{kJ}{kg\cdot K} - 2.9294\,\frac{kJ}{kg\cdot K} \right)$

$S_{gen} = 18.519\,\frac{kJ}{K}$

Serga [27]

Answer:

Explanation:

* Daily close of the stock market

The nature of the signal in value is Discrete, as the stock market closes once per day,and so is discrete time.
And the nature of the signal in time is continuous as the company are continuous.
