The maximum PCM bit rate is 4 bits/sample x 12,000 samples/second is 48 kbps.

The maximum bandwidth that can be permitted for the analog signal is equal to the channel bandwidth, which is 4 kHz.

We have,

A)

To find the maximum PCM bit rate without introducing ISI, we need to ensure that the sampling rate is greater than twice the channel bandwidth.

The Nyquist sampling rate for a 4 kHz bandwidth is 8 kHz.

The raised cosine filter roll-off factor r = 0.5 means that the transition bandwidth is 50% of the symbol rate.

Therefore, the symbol rate must be twice the channel bandwidth plus 50% of the symbol rate, or 2 x 4 kHz x 1.5 = 12 kHz.

Since the PCM system has 16 quantization levels, each sample will require 4 bits (log2 16 = 4).

The maximum PCM bit rate is 4 bits/sample x 12,000 samples/second.

= 48 kbps.

B)

The maximum bandwidth that can be permitted for the analog signal is equal to the channel bandwidth, which is 4 kHz.

This is determined by the Nyquist sampling theorem, which states that the maximum frequency that can be accurately represented in a sampled signal is half the sampling rate.

Since the system is bandlimited to 4 kHz, we need to sample at a rate of at least 8 kHz to accurately represent the signal, and the maximum frequency component that can be represented is 4 kHz.

Thus,

The maximum PCM bit rate is 4 bits/sample x 12,000 samples/second is 48 kbps.

The maximum bandwidth that can be permitted for the analog signal is equal to the channel bandwidth, which is 4 kHz.

The best specification for the `is Inside` method in the Circle class would be to check if the distance between the center of the circle and the given Point is less than the radius of the circle.

The `is Inside` method determines whether a given Point lies inside a Circle. One way to do this is by checking if the distance between the center of the Circle and the given Point is less than the radius of the Circle. If the distance is less than the radius, the Point is inside the Circle; otherwise, it is outside.

This approach is based on the geometric definition of a Circle, where all points on the circumference are equidistant from the center. By calculating the distance between the center of the Circle and the given Point, we can compare it to the radius to determine if the Point falls within the Circle.

By using this specification, the `is Inside` method can accurately determine if a Point lies inside the Circle, providing a reliable and intuitive implementation.

a) To make up a 32G × 64 memory, each word being 64 bits in size, we need a total of 32G words. Since each RAM chip has a capacity of 1G × 16, we can calculate the number of RAM chips necessary: = 32 chips

Number of RAM chips = (32G words) / (1G words/chip)

                   = 32 chips

b) Assuming four chips per bank, the number of banks required can be calculated by dividing the total number of chips by the number of chips per bank:

Number of banks = (Number of RAM chips) / (Chips per bank)

              = 32 chips / 4 chips/bank

              = 8 banks

c) Each chip has a word width of 16 bits (1G × 16). To address each chip, we need a total of 16 lines.

d) For a memory that is word addressable, the number of bits needed for a memory address is calculated as follows:

Number of bits = log2(32G words)

              = log2(2^35)   (since 32G = 2^35)

              = 35 bits

e) For chip select, we need enough bits to uniquely identify each chip. Since we have 32 chips, we need 5 bits (2^5 = 32) for chip select. The remaining 30 bits will be used for the address on the chip.

Diagram:

```

----------------------------

|   Chip Select   | Address |

----------------------------

|   5 bits        | 30 bits |

f) If low-order interleaving is being used, the number of banks required will be equal to the number of chips. So, in this case, there would be 32 banks. The rest of the calculations for the number of RAM chips, lines per chip, and the number of bits for memory address would remain the same as in parts (a), (c), and (d). The diagram for chip select and address on the chip would also remain the same.

The true strain is a more accurate and precise measure of deformation than the engineering strain. At low strains, the engineering strain is a good approximation of the true strain.

As the strain grows, the difference between the engineering strain and the true strain grows, as you’ve stated. When the true strain is substantial, the difference between the two strains is large.

This is due to the fact that engineering strain calculates the change in length as a proportion of the original length, whereas true strain calculates the change in length as a proportion of the current length.

The statement that The different taste qualities (sweet, sour, bitter, salt, umami) each have their own area of the tongue that is most sensitive to them is False.

Gate Theory states that competing signals such as rubbing your elbow can make you more sensitive to pain. This theory suggests that physical signals such as massage, pressure, heat, or cold can block the transmission of pain messages through the spinal cord and prevent them from reaching the brain. Therefore, when people rub their elbows or apply pressure to the area, this stimulates the non-painful touch fibers and decreases the transmission of the painful stimuli.

As per the statement, patients who are allowed to self-administer morphine use less than when they receive injections from healthcare providers is True.

1) What is the cycle time for operation?

2) What is the theoretical minimum number of workstation?

Answer:

1) the cycle time for operation is 9.6 min

2) the theoretical minimum number of workstation is 5

Explanation:

Given the data in the question;

production time per day = 480 minutes

average daily demand = 50

Given the data in the question;

1) cycle time for operation

this is simply referred to as the total time for the process from start to finish.

cycle time = production time per day / units demand per day

we substitute

cycle time = 480 min / 50

cycle time = 9.6 min

Therefore, the cycle time for operation is 9.6 min

2) theoretical minimum number of workstation.

theoretical minimum number of workstation = total task time / cycle time

Total task time = ( 4 + 7 + 6 + 5 + 6 + 7 + 8 + 6 ) = 49 min

∴  theoretical minimum number of workstation = 49 min / 9.6 min

theoretical minimum number of workstation = 5.104 ≈ 5

Therefore, the theoretical minimum number of workstation is 5

The given statement "the heavier the current flow for a given voltage, the larger the value for admittance." is true because admittance is the measure of how easily current flows through a circuit, so if the current flow is heavier for a given voltage, it means there is less resistance and therefore a larger value for admittance.

The admittance is a measure of how easily a circuit can conduct an alternating current (AC). It is the reciprocal of impedance and is measured in siemens (S) or mhos.

The heavier the current flow for a given voltage, the lower the value for impedance, and therefore, the higher the value for admittance. This is because a higher current flow indicates less opposition to the flow of current, which results in lower impedance and higher admittance. Therefore, the statement "the heavier the current flow for a given voltage, the larger the value for admittance" is false.

Answer:

A) L = 0.388 μm

B) D = 3.78 mm

Explanation:

We are given;

Characteristics impedance; Z_o = 75 ohms

Nominal capacitance; C = 69pF/m = 69 × 10^(-12) F/m

dielectric constant; k = 2.23

Inner diameter of conductor; d = 0.584 mm

A) Now formula for Characteristics impedance is given as;

Z_o = √(L/C)

Where L is the inductance per metre.

Making L the subject, we have;

L = (Z_o)²C

L = 75² × 69 × 10^(-12)

L = 0.388 × 10^(-6) m

L = 0.388 μm

B) To get the outer diameter, we will use the formula;

Z_o = (138/√k) log(D/d)

Where;

D is outer diameter.

Thus, Plugging in the relevant values;

75 = (138/√2.23) × log (D/0.584)

log (D/0.584) = 0.81158611538

(D/0.584) = 10^(0.81158611538)

D/0.584 = 6.48016576435

D = 6.48016576435 × 0.584

D = 3.78 mm

The magnitude of σ1 that will cause yielding according to the maximum-shear-stress theory is 9.94 ksi.

Yield stress for the zirconium-magnesium alloy, σY = 15.3 ksi

In-plane principal stresses are σ1 and σ2 = −0.54σ1

To find the maximum shear stress theory, the equation used is τ_max=1/2(σ1-σ2)

The maximum shear stress theory states that yielding begins when the maximum shear stress in a part equals or exceeds the shear strength of the material. It is represented as τ_max = τ_yield

Where τ_max is the maximum shear stress in a part and τ_yield is the shear strength of the material. In-plane principal stresses are σ1 and σ2 = −0.54σ1

Let us replace the value of σ2 in terms of σ1σ2 = −0.54σ1,σ1 = 1.85σ2

Substitute the values in the τ_max=1/2(σ1-σ2)

τ_max=1/2(σ1-(-0.54σ1))

τ_max=0.77σ1

Now, τ_yield= σY/2 = 7.65 ksi

Therefore, 0.77σ1 = 7.65

σ1 = 9.94 ksi

Answer:

The container should be made of lead and the liquid should be water.

Explanation:

Since the volume of the container of liquid after expansion is V = V₀(1 + βΔθ) where V = initial volume, β = coefficient of volume expansion, Δθ = temperature change.

So, the volume change V₂ - V₁ where V₁ = volume of liquid and V₂ = volume of container

For steel, V₂ = V₀(1 + β₂Δθ) and V₁ = V₀(1 + β₁Δθ)

So, ΔV = V₀(1 + β₂Δθ) - V₀(1 + β₁Δθ) = V₀[1 + β₂Δθ - 1 - β₁Δθ] = V₀[β₂Δθ - β₁Δθ]

Since we want a minimum value for ΔV and V₀ and Δθ are the same, we need ΔV/V₀Δθ = β₂ - β₁ to be a minimum

where β₂ = coefficient of volume expansion of liquid and β₁ = coefficient of volume expansion of container.

So, trying each combination, with  β₂ = 207 × 10⁻⁶ (C°)⁻¹] and β₁ = 36 × 10⁻⁶ (C°)⁻¹

β₂ - β₁ = 207 × 10⁻⁶ (C°)⁻¹ - 36 × 10⁻⁶ (C°)⁻¹ = 171 × 10⁻⁶ (C°)⁻¹

With  β₂ = 207  × 10⁻⁶ (C°)⁻¹] and β₁ = 87  × 10⁻⁶ (C°)⁻¹

β₂ - β₁ = 207 × 10⁻⁶ (C°)⁻¹ - 87 × 10⁻⁶ (C°)⁻¹ = 120 × 10⁻⁶ (C°)⁻¹

With  β₂ = 1120 × 10⁻⁶ (C°)⁻¹] and β₁ = 36  × 10⁻⁶ (C°)⁻¹

β₂ - β₁ = 1120 × 10⁻⁶ (C°)⁻¹ - 36 × 10⁻⁶ (C°)⁻¹ = 1084 × 10⁻⁶ (C°)⁻¹

With  β₂ = 1120 × 10⁻⁶ (C°)⁻¹] and β₁ = 87 ×  10⁻⁶ (C°)⁻¹

β₂ - β₁ = 207 × 10⁻⁶ (C°)⁻¹ - 87 × 10⁻⁶ (C°)⁻¹ = 1033 × 10⁻⁶ (C°)⁻¹

The combination that gives the lowest value for β₂ - β₁ is β₂ = 207 × 10⁻⁶ (C°)⁻¹] and β₁ = 87 × 10⁻⁶ (C°)⁻¹

Since  β₁ = 87 × 10⁻⁶ (C°)⁻¹ = coefficient of expansion for lead β₂ = 207 × 10⁻⁶ (C°)⁻¹]  = coefficient of expansion for water, the container should be made of lead and the liquid should be water.

That means that the total amount earned by those 5 is;

5 x $15 = $75 per hour

(ii) 4 people earn $17 per hour

That means that the total amount earned by those 4 is;

4 x $17 = $68 per hour

(iii) The remaining people earn $16 per hour.

There are 7 people remaining. i.e
