Answer:

Resistance of copper = 1.54 * 10^18 Ohms

Explanation:

Given the following data;

Length of copper, L = 3 kilometers to meters = 3 * 1000 = 3000 m

Resistivity, P = 1.7 * 10^8 Ωm

Diameter = 0.65 millimeters to meters = 0.65/1000 = 0.00065 m

\( Radius, r = \frac {diameter}{2} \)

\( Radius = \frac {0.00065}{2} \)

Radius = 0.000325 m

To find the resistance;

Mathematically, resistance is given by the formula;

\( Resistance = P \frac {L}{A} \)

Where;

First of all, we would find the cross-sectional area of copper.

Area of circle = πr²

Substituting into the equation, we have;

Area  = 3.142 * (0.000325)²

Area = 3.142 * 1.05625 × 10^-7

Area = 3.32 × 10^-7 m²

Now, to find the resistance of copper;

\( Resistance = 1.7 * 10^{8} \frac {3000}{3.32 * 10^{-7}} \)

\( Resistance = 1.7 * 10^{8} * 903614.46 \)

Resistance = 1.54 * 10^18 Ohms

The correct answer is Ballast or transformer. In an indirect lights control system, when a bulb stops glowing, you might also need to check the ballast or transformer.

Indirect lighting systems often use additional components like ballasts or transformers to regulate the power supply to the bulbs. These components are responsible for converting the electrical current to the appropriate voltage and current required by the bulbs. If a bulb fails to glow in an indirect lighting system, it could indicate a problem with the ballast or transformer, which may need to be checked or replaced. This distinguishes it from a normal lighting system where only the bulb itself would typically need to be checked.

In point 2:

\(\to V_A=V_C\\\\\to \pi D_A N_A=\pi D_C N_C\\\\\to D_C=\frac{D_A \times N_A}{N_C}\\\\\)

          \(=\frac{1000 \times 18}{1850}\\\\=9.729 \ in \ \ \text{Diameter of pulley B}\)

Fourth-order Low Pass  Filter If the gain of both filters is set at 1.586, the voltage gain will be down 6 dB at the cutoff frequency. We can get a more flat response by choosing different values of voltage gain for both stages.

It is possible to create a 4th order low-pass filter with just one Op Amp. Due to the interconnected nature of all filter parameters, component tolerance sensitivity needs to be confirmed. The 4th order Sallen-Key topology is too sensitive to component tolerances, making it unsuitable for application.

 Formula fc= 1/(2πRC).

The attenuation rate for a low-pass or high-pass filter will be -20 times the filter order, expressed in decibels per decade. A first-order filter, for instance, will attenuate at a rate of -20 dB/decade, but a fourth-order filter will attenuate at a rate of about -80 dB/decade.

The boat is approximately 67.3 nautical miles from the port (rounded to one decimal place).

To determine the distance of the boat from the port, we can break down the boat's movement into two legs: the first leg traveling on the N75E course and the second leg traveling on the S29E course.

First, let's calculate the distance covered in the first leg:

Distance = Speed × Time

Speed = 9 knots

Time = 3 hours and 20 minutes = 3.33 hours (rounded to two decimal places)

Distance of the first leg = 9 knots × 3.33 hours = 29.97 nautical miles (rounded to two decimal places)

Next, let's calculate the distance covered in the second leg:

Speed = 12 knots

Time = 5 hours

Distance of the second leg = 12 knots × 5 hours = 60 nautical miles

To find the total distance from the port, we need to calculate the vector sum of the two distances:

Total distance = √((Distance of first leg)² + (Distance of second leg)²)

Total distance = √((29.97)² + (60)²) ≈ 67.34 nautical miles (rounded to two decimal places).

Therefore, the boat is approximately 67.3 nautical miles from the port (rounded to one decimal place).

The maximum capillary rise and tube diameter for this maximum-rise case will be d=0.414× 10⁻⁴ m.

What do you mean by tube?

A tube, also known as tubing, is a long hollow cylinder that is used to transport fluids (liquids or gases) or to protect electrical and optical cables and wires.

Given that, P = 4 KPa

Contact angle = 6°

Surface tension = 1 N/m

Lets assume that atmospheric pressure = 100 KPa

Lets take that density of water = 1000kg/m³

So the capillarity rise h

h=ΔP/ρg

h= (100×1000-4×1000)/(1000×10)

h= 9.61 m

We know that for capillarity rise h

h=2σcosθ/rρg

r = 2σcosθ/hρg

r = (2×1cos4°)/(9.61×1000×10)

(b) convert A₂ to polar and exponential form

(c) calculate A₃ = (A₁ + A₂), giving your answer in polar form

(d) calculate A₄ = A₁A₂, giving your answer in rectangular form

(e) calculate A₅ = A₁/(\(A^{*}\)₂), giving your answer in exponential form.

Answer:

a) A₁ in rectangular form is 5.196 + j3

b) value of A₃  in polar form is 12.19∠41.02°

The polar form of A₂ is 6.403 ∠51.34°, exponential form of A₂ = 6.403\(e^{j51.34 }\)

c) value of A₃  in polar form is 12.19∠41.02°

d) A₄ in rectangular form is 5.784 + j37.98

e) A₅ in exponential form is 0.937\(e^{j81.34 }\)

Explanation:

Given data in the question;

a) A₁ = 6∠30

we convert A₁ to rectangular form

so

A₁ = 6(cos30° + jsin30°)

= 6cos30° + j6cos30°

= (6 × 0.866) + ( j × 6 × 0.5)

A₁  =  5.196 + j3

Therefore, A₁ in rectangular form is 5.196 + j3

b) A₂ = 4 + j5

we convert to polar and exponential form;

first we convert to polar form

A₂ = √((4)² + (5)²) ∠tan⁻¹( \(\frac{5}{4}\) )

= √(16 + 25) ∠tan⁻¹( 1.25 )

= √41 ∠ 51.34°

A₂ = 6.403 ∠51.34°

The polar form of A₂ is 6.403 ∠51.34°

next we convert to exponential form;

A∠β can be written as A\(e^{j\beta }\)

so, A₂  in exponential form will be;

A₂ = 6.403\(e^{j51.34 }\)

exponential form of A₂ = 6.403\(e^{j51.34 }\)

c) A₃ = (A₁ + A₂)

giving your answer in polar form

so, A₁ = 6∠30 = 5.196 + j3 and A₂ = 4 + j5

we substitute

A₃ = (5.196 + j3) + ( 4 + j5)

= 9.196 + J8

next we convert to polar

A₃ = √((9.196)² + (8)²) ∠tan⁻¹( \(\frac{8 }{9.196}\) )

A₃ = √(84.566416 + 64) ∠tan⁻¹( 0.8699)

A₃ = √148.566416 ∠41.02°    

A₃ = 12.19∠41.02°

Therefore, value of A₃  in polar form is 12.19∠41.02°

d) A₄ = A₁A₂

giving your answer in rectangular form

we substitute

A₄ = (5.196 + j3) ( 4 + j5)

= 5.196( 4 + j5) + j3( 4 + j5)

= 20.784 + j25.98 + j12 - 15

A₄ = 5.784 + j37.98

Therefore, A₄ in rectangular form is 5.784 + j37.98

e) A₅ = A₁/(\(A^{*}\)₂)

giving your answer in exponential form

we know that \(A^{*}\)₂ is the complex  conjugate of A₂

so

\(A^{*}\)₂ = (6.403 ∠51.34° )*

= 6.403 ∠-51.34°

we convert to exponential form

A∠β can be written as A\(e^{j\beta }\)

\(A^{*}\)₂  = 6.403\(e^{-j51.34 }\)

also

A₁ = 6∠30

we convert to polar form

A₁ = 6\(e^{j30 }\)

so A₅ = A₁/(\(A^{*}\)₂)

A₅ = 6\(e^{j30 }\) / 6.403\(e^{-j51.34 }\)

A₅  = (6/6.403) \(e^{j(30+51.34) }\)

A₅  = 0.937\(e^{j81.34 }\)

Therefore A₅ in exponential form is 0.937\(e^{j81.34 }\)

The RPM of the single-acting compressor is 300 revolutions per minute if the stroke is 8 inches and the piston speed is 400 feet per minute.

RPM is an abbreviation for revolutions per minute which is used to indicate the speed of a thing by determining how many times it turns one complete circle during one minute.

To determine the RPM in this case, we use the formula for piston speed as follows;

Piston speed = ( 2 × Stroke × RPM ) ÷ 12

As the stroke is given to be 8 inches and the piston speed is given to be 400 feet per minute, substituting these values in the equation as follows;

400 = ( 2 × 8 × RPM ) ÷ 12

400 × 12 = 16 × RPM

4800 = 16 × RPM

RPM = 4800 ÷ 16

RPM = 300

Therefore this single-acting compressor is determined to have 300 revolutions per minute.

A auto transformer is any transformer in which the primary and secondary circuits have a portion of their two windings in common.

What is transformer?
A transformer is a passive part that moves electrical energy between circuits, whether they be single circuits or multiple circuits. The electromotive force (EMF) across any coils wound around the same core changes in response to changes in the current flowing through any one of the transformer's coils, which causes changes in the magnetic flux in the transformer's core. Without a metallic (conductive) connection between this same two circuits, electrical energy can be transferred between different coils. The 1831 discovery of Faraday's law of induction defines the induced voltage effect in any coil as the result of a fluctuating magnetic flux surrounding the coil.
