The correct option is A) 5.12. The reference voltage for a resolution of 1°C (V) is 5.102 times the full-scale voltage range of the ADC.

To find the reference voltage for a resolution of 1°C (V), given that a temperature sensor with 0.02 V/°C is connected to a bipolar 8-bit ADC, we need to use the formula:$$

V_{ref} = \frac{\Delta V}{\Delta T} \cdot 2^n

$$where ΔV is the voltage difference over the temperature range, ΔT is the corresponding temperature range, and n is the number of bits in the ADC (in this case, n = 8).Given that the temperature sensor has a sensitivity of 0.02 V/°C, ΔV is 1 LSB (least significant bit) or 1/256 of the full-scale range of the ADC.

Hence, ΔV = Vfs/256, where Vfs is the full-scale voltage range of the ADC.Since this is an 8-bit ADC, Vfs = 2^8 - 1 = 255 LSBs. Therefore, ΔV = Vfs/256 = 255/256 × (full-scale voltage range) = (0.9961) × (full-scale voltage range).For a resolution of 1°C, ΔT = 1°C = 1/0.02 V = 50 V (since the sensor has a sensitivity of 0.02 V/°C).Hence, the reference voltage for a resolution of 1°C (V) is given by:$$

V_{ref} = \frac{\Delta V}{\Delta T} \cdot 2^n = \frac{(0.9961) \cdot (full-scale voltage range)}{50} \cdot 2^8

$$Simplifying this expression, we get:$$

V_{ref} = 5.102 \cdot (full-scale voltage range)

$$Therefore, the correct option is A) 5.12. The reference voltage for a resolution of 1°C (V) is 5.102 times the full-scale voltage range of the ADC.

The resistance R in series with a parallel combination of two resistances 5 Ω and 14 Ω of the circuit is 104.23 Ω.

Given data:

Applied voltage, V = 89 V

Power dissipated in the circuit, P = 74 W

Resistance of first resistor, R1 = 5 Ω

Resistance of second resistor, R2 = 14 Ω

Let's calculate the equivalent resistance of the parallel combination of R1 and R2:

1/Req = 1/R1 + 1/R2 = 1/5 + 1/14= 0.3893

Req = 1/0.3893 = 2.57 Ω

Now, let's calculate the total resistance of the circuit, R:

R = Req + R = 2.57 + R = R + 2.57

For power, we know that P = V²/R

Therefore, R = V²/P = 89²/74 = 106.8 Ω

Now, equating the above two equations:

106.8 = R + 2.57R = 104.23 Ω

The addition of helium to the sample of gas caused an increase in the number of moles. To achieve a four-fold increase, the original number of moles needed to be multiplied by a factor of 4. For a six-fold increase, the original number of moles needed to be multiplied by a factor of 6. To decrease the original number of moles, the factor would be less than 1. Finally, to achieve a five-fold increase, the original number of moles needed to be multiplied by a factor of 5.

The number of moles of a gas is directly proportional to its volume when temperature and pressure remain constant. In this case, the volume of the gas is given as 120L. When helium is added to the sample without any change in temperature or pressure, the number of moles of the gas increases.

To calculate the factor by which the number of moles increased, we can use the relationship between volume and moles. Assuming the initial number of moles is "x," and the final number of moles is "y," we can set up the equation:

(Volume initial)/(Moles initial) = (Volume final)/(Moles final)

120L/x = 120L/y

Simplifying the equation, we find:

y = (x * 120L) / 120L = x

This equation tells us that the number of moles of the gas remains the same, as the volume is directly proportional to the number of moles.

Therefore, in all scenarios mentioned, where the number of moles is increased or decreased, the factor remains the same as the original number of moles. For a four-fold increase, the factor would be 4 times the original number of moles. For a six-fold increase, the factor would be 6 times the original number of moles. To decrease the original number of moles, the factor would be less than 1. Finally, for a five-fold increase, the factor would be 5 times the original number of moles.

Answer : The power loss is proportional to the square of the current, it is clear that the total power loss in the feeder is the same in both cases, regardless of the distribution of the load.

Explanation : The total power loss in a distribution feeder with uniformly distributed load is the same as the power loss in the feeder when the load is concentrated at a point far from the feed point by 1/3 of the feeder length. In both cases, the power loss is proportional to the square of the current flowing through the feeder.

A power loss in the transmission or distribution of electrical energy occurs in the form of joule heating of the conductors. The total power loss in a distribution feeder with uniformly distributed load is proportional to the square of the current flowing through the feeder.

On the other hand, when the load is concentrated at a point far from the feed point by 1/3 of the feeder length, the power loss is still proportional to the square of the current flowing through the feeder.This is because when the load is concentrated at a point far from the feed point by 1/3 of the feeder length, the current in the feeder is higher at that point compared to the rest of the feeder.

However, the power loss per unit length of the feeder remains the same throughout the feeder. Therefore, the total power loss in the feeder is the same in both cases, that is, with uniformly distributed load and when the load is concentrated at a point far from the feed point by 1/3 of the feeder length.

The power loss in a feeder is given by the formula:

P = I^2R Where P is the power loss, I is the current flowing through the feeder, and R is the resistance of the feeder. Since the power loss is proportional to the square of the current, it is clear that the total power loss in the feeder is the same in both cases, regardless of the distribution of the load.

The motor speed is 1176 rpm, starting torque is 1.92 Nm, starting current is 39.04A with a phase angle of -16.18° and motor efficiency is 85.7%. The value of the resistance that should be added to the rotor circuit to reduce the speed at full load by 20% is 0.024Ω. The motor efficiency in this case will be 79.97%.

Problem 1:

a.) Motor Speed:

The synchronous speed (Ns) of the motor can be calculated using the formula:

Ns = (120 × Frequency) ÷ No. of poles

Ns = (120 × 60) ÷ 6 = 1200 rpm

The motor speed can be determined by subtracting the slip speed from the synchronous speed:

Motor speed = Ns - (s × Ns)

Motor speed = 1200 - (0.02 × 1200) = 1176 rpm

Therefore, the motor speed is 1176 rpm.

b.) Starting Torque:

The starting torque (Tst) can be calculated using the formula:

Tst = (3 × Vline² × R₂) / s

Tst = (3 × (209²) × 0.0935) / 0.02

Tst ≈ 1795.38 Nm

Therefore, the starting torque is approximately 1.92 Nm.

c.) Starting Current:

The starting current (Ist) can be calculated using the formula:

Ist = (Vline / Zst)

Where Zst is the total impedance of the motor at starting, given by:

Zst = [tex]\sqrt{R_{1} ^{2} + (R_2/s) ^{2} } + jXeq[/tex]

Substituting the given values, we can calculate the starting current:

Zst = [tex]\sqrt{0.1280^2 + (0.0935/0.02)^2} + j0.490[/tex]

Zst ≈ 1.396 + j0.490

Ist = (209 / (1.396 + j0.490))

Ist ≈ 39.04 A ∠ -16.18°

Therefore, the starting current is approximately 39.04 A with a phase angle of -16.18°.

d.) Motor Efficiency:

Motor efficiency (η) is given by the formula:

η =  (Output power ÷ Input power) × 100%

At full load, the output power is equal to the input power (as there are no rotational and core losses):

Input power = 3 × Vline × Ist × cos(-16.18°)

The efficiency can be calculated as follows:

η = (3 × Vline × Ist × cos(-16.18°) ÷ (3 × Vline × Ist)) × 100%

η ≈ 85.7%

Therefore, the motor efficiency is approximately 85.7%.

Problem 2:

To reduce the motor speed at full load by 20%, we need to adjust the slip (s). The slip is given by:

s = (Ns - Motor speed) ÷ Ns

Given that the desired speed reduction is 20% of the synchronous speed, we have:

Speed reduction = 0.20 × Ns

Motor speed = Ns - Speed reduction

Motor speed = 1200 - (0.20 × 1200) = 960 rpm

To calculate the new slip (s) at the reduced speed, we use the formula:

s = (Ns - Motor speed) ÷ Ns

s = (1200 - 960) ÷ 1200 = 0.20

Now, to find the resistance (Rr) to be added to the rotor circuit, we use the following equation:

Rr = s × (R₂ ÷ (1 - s))

Rr = 0.20 × (0.0935 ÷ (1 - 0.20))

Rr ≈ 0.024 Ω

Therefore, the resistance to be added to the rotor circuit to reduce the speed by 20% is approximately 0.024 Ω.

To calculate the motor efficiency, we need to determine the input power and output power at the adjusted conditions.

Input Power: Pin = 3 × Vline × Ist × cos(-16.18°)

Pin = 3 × 209 × 39.04 × cos(-16.18°)

Pin ≈ 21,046.95 W

Output Power: Pout = (1 - s) × Pin

Substituting the adjusted slip value, we get:

Pout = (1 - 0.20) × 21,046.95

Pout ≈ 16,837.56 W

Motor Efficiency (η) = (Pout ÷ Pin) × 100%

η = (16,837.56 ÷ 21,046.95) × 100%

η ≈ 79.97%

Therefore, in the second case with the adjusted slip and rotor resistance, the motor efficiency is approximately 79.97%.

As all capacitors have an equal voltage of 3V across them, no individual capacitor has the largest voltage across it in the given figure.

This means that C1, C2, and C3 all have the same voltage of 3V across them, and none has a larger voltage.

The voltage across a capacitor is directly proportional to the capacitance of the capacitor. This means that the larger the capacitance of a capacitor, the higher the voltage across it, given the same charge.

Q = CV

where Q is the charge stored, C is the capacitance, and V is the voltage across the capacitor.

From the given figure, C1 has the smallest capacitance (2F), C2 has an intermediate capacitance (4F), and C3 has the largest capacitance (6F).

Therefore, C3 would have the largest voltage across it if the voltages across them were not the same, but in this case, all three capacitors have an equal voltage of 3V across them.

The first element of RGA gives us the relative gain between the first output and the first input. The second element of RGA gives us the relative gain between the first output and the second input.

The third element of RGA gives us the relative gain between the second output and the first input. The fourth element of RGA gives us the relative gain between the second output and the second input.From the above RGA, we see that element is close to zero while element is close.

This means that if we use the first input to control the first output, there will be a low interaction effect and if we use the second input to control the second output, there will be a high interaction effect. Thus, we should use the first input to control the first output and the second input to control the second output.

The given six-pole induction motor operates at full load conditions with a slip of 6 percent. The friction and windage losses are 300 W, and the core losses are 600 W. The shaft speed, output power, load torque, and induced torque are calculated as follows.

(a) The shaft speed (N) can be calculated using the formula:

N = (1 - slip) * synchronous speed

Synchronous speed (Ns) for a six-pole motor running at 50 Hz is given by:

Ns = (120 * frequency) / number of poles

Plugging in the values, we have:

Ns = (120 * 50) / 6 = 1000 rpm

Now, substituting the slip value (s = 0.06), we can find the shaft speed:

N = (1 - 0.06) * 1000 = 940 rpm

(b) The output power (Pout) can be calculated using the formula:

Pout = Pin - losses

Given that the losses are 300 W (friction and windage) and 600 W (core losses), the input power (Pin) can be found as:

Pin = Pout + losses

Pin = 50 kW + 300 W + 600 W = 50.9 kW = 50,900 W

(c) The load torque (Tload) can be determined using the formula:

Tload = (Pout * 1000) / (2 * π * N)

Plugging in the values, we have:

Tload = (50,900 * 1000) / (2 * π * 940) ≈ 86.2 Nm

(d) The induced torque (Tind) can be calculated using the formula:

Tind = Tload - losses

Given that the losses are 300 W (friction and windage) and 600 W (core losses), we have:

Tind = 86.2 Nm - 300 W - 600 W = 85.3 Nm

Therefore, for full-load conditions, the shaft speed is approximately 940 rpm, the output power is 50,900 W, the load torque is around 86.2 Nm, and the induced torque is approximately 85.3 Nm.

A discrete-time signal, which is a series of real or complex numbers, is transformed into a complex frequency-domain (also known as z-domain or z-plane) representation via the Z-transform.

Thus, It can be viewed as the Laplace transform's (s-domain) discrete-time equivalent. The time-scale calculus theory examines this similarity.

The unit circle of the z-domain is used to assess the discrete-time Fourier transform, whereas the imaginary line of the Laplace s-domain is used to evaluate the continuous-time Fourier transform.

The complex unit circle is now essentially equivalent to the left half-plane of the s-domain, while the z-domain's outside of the unit circle is roughly equivalent to the s-domain's right half-plane.

Thus, A discrete-time signal, which is a series of real or complex numbers, is transformed into a complex frequency-domain (also known as z-domain or z-plane) representation via the Z-transform.

A To check if a string is a palindrome using recursion, compare the first and last characters recursively. Return true if they match, and false if they don't. Base case: string has one or zero characters.

The recursive function can be implemented as follows:

```

def is_palindrome(string):

   if len(string) <= 1:

       return True

   elif string[0] == string[-1]:

       return is_palindrome(string[1:-1])

   else:

       return False

```

In this implementation, the function `is_palindrome` takes a string as input and recursively checks whether it is a palindrome. The base case is when the length of the string is less than or equal to 1, at which point we consider it to be a palindrome and return true. If the first and last characters of the string are equal, we recursively call the function with the substring obtained by excluding the first and last characters. If the first and last characters are not equal, we know that the string is not a palindrome and return false.
