The resistivity of gold at room temperature is approximately 2.44×10⁻⁸ Ωm

To find the resistivity of gold at room temperature, you can use the formula for resistivity, which is given by:
Resistivity (ρ) = m / (n * e² * τ)
where m is the mass of an electron, n is the free electron density, e is the charge of an electron, and τ is the mean free time between electron collisions. We can calculate τ using the mean free path (λ) and Fermi velocity (vF), given by:
τ = λ / vF

To calculate the Fermi velocity, we can use the formula:
vF = sqrt(2 * EF / m)
where EF is the Fermi energy of gold. Let's now calculate the resistivity step by step.

1. Calculate the Fermi velocity:
vF = sqrt(2 * 8.86×10⁻¹⁹ J / 9.11×10⁻³¹ kg)
vF ≈ 1.39×10⁶ m/s

2. Calculate the mean free time between electron collisions:
τ = 3.45×10⁻⁸ m / 1.39×10⁶ m/s
τ ≈ 2.49×10⁻¹⁵ s

3. Calculate the resistivity of gold at room temperature:
ρ = (9.11×10⁻³¹ kg) / (5.90×10²⁸ m⁻³ * (1.6×10⁻¹⁹ C)² * 2.49×10⁻¹⁵ s)
ρ ≈ 2.44×10⁻⁸ Ωm

So, the resistivity of gold at room temperature is approximately 2.44×10⁻⁸ Ωm.

The largest commonly-used drill bit size among the options provided is 2 inches.

The correct answer to the given question is option C.

Drill bits are used for creating holes in various materials, and their sizes are typically measured in inches. The size of a drill bit refers to its diameter, and larger drill bits are commonly used for specific applications that require larger holes.

While drill bits larger than 2 inches do exist, they are not as commonly used in typical DIY or commercial applications. In everyday projects, such as woodworking, construction, or metalworking, the majority of holes can be adequately drilled using smaller-sized bits.

Option A (1.5 inches) and option D (1 inch) represent smaller drill bit sizes that are more commonly used for general-purpose drilling tasks. Option B (12 inches) represents an extremely large drill bit size that is not commonly used in most standard applications.

It's important to note that drill bit sizes can vary depending on specific needs and industries. There may be specialized applications or industries that require even larger drill bits beyond the commonly-used range. However, in the context of commonly-used drill bits for general-purpose tasks, 2 inches represents a relatively large size.

The probability that one telephone call passes through the switchboard in three minutes is 1.49%.

Using the Poisson probability formula, we can calculate the probability of exactly one call passing through the switchboard in 3 minutes as follows:

P(X = 1) = (e^(-6) * 6^1) / 1!

Where

6 = 2 per minute * 3 minute

X is the number of calls passing through the switchboard in 3 minutes.

So, we have

P(X = 1) = (e^(-6) * 6^1) / 1!

= (0.00248 * 6) / 1

= 0.0149

Answer: 75,000 Hz

Explanation:

To calculate the frequency of the supply voltage, we need to use the formula:

frequency = 1 / time period

where the time period is the time it takes for one complete cycle of the waveform. For a sine wave, the time period is given by:

time period = 2π / angular frequency

where the angular frequency is the rate of change of the angle with respect to time and is given by:

angular frequency = 2π × frequency

Comparing the given voltage expression v = 240 sin (471,239t) V to the general form of a sine wave:

v = Vm sin(ωt + θ)

where Vm is the amplitude, ω is the angular frequency, t is time, and θ is the phase angle, we can see that the amplitude is 240 V, the angular frequency is 471,239 rad/s, and there is no phase angle (θ = 0).

Using the formula for angular frequency, we can find the frequency:

angular frequency = 2π × frequency

471,239 = 2π × frequency

frequency = 471,239 / (2π) ≈ 75,000 Hz

Therefore, the frequency of the supply voltage is approximately 75,000 Hz.

A heat engine would have 100% efficiency if its low-temperature reservoir were at absolute zero. This is known as the Carnot efficiency limit and is a theoretical maximum for the efficiency of a heat engine.

A heat engine is a device that converts thermal energy into mechanical energy. It operates by using a temperature difference between a hot reservoir and a cold reservoir to do work. The efficiency of a heat engine is defined as the ratio of the work output to the heat input, and it is always less than 100% due to losses in the system.

The Carnot efficiency limit is a theoretical maximum for the efficiency of a heat engine. It is based on the idea of a reversible engine that operates in a cycle between two heat reservoirs, with no heat loss to the surroundings. The efficiency of a Carnot engine depends only on the temperatures of the two reservoirs and is given by the formula:

efficiency = 1 - (T low / T high)

where T low is the temperature of the low-temperature reservoir, and T T T high is the temperature of the high-temperature reservoir.

If the low-temperature reservoir were at absolute zero (0 Kelvin or -273.15 Celsius), the efficiency of the Carnot engine would be 100%, which is the theoretical maximum for any heat engine. However, achieving absolute zero is impossible in practice, so real-world heat engines will always have less than 100% efficiency.

The new plant would require 4 forging cells.

The proportion is  10.07%.

Total available working time per year:

24 hours/day * 5 days/week * 50 weeks/year

= 6,000 hours/year

Total parts required including scrap:

800,000 forgings / (1 - 0.03)

= 800,000 / 0.97

≈ 824,742 forgings

Number of batches required:

824,742 forgings / 1,250 parts per batch

≈ 660 batches

Total forging time (excluding changeover time) for 824,742 parts:

1.5 minutes/part * 824,742 parts * (1 hour / 60 minutes)

≈ 20,618.55 hours

Total changeover time for 660 batches:

660 batches * 3.5 hours/changeover

≈ 2,310 hours

Total time required to produce 824,742 forgings, including changeovers:

20,618.55 hours + 2,310 hours

≈ 22,928.55 hours

Now, considering the availability of each cell during operation (96%):

Effective operation time required

= 22,928.55 hours / 0.96

≈ 23,883.49 hours

Now, we can determine the number of forging cells needed to meet production requirements:

Number of cells = Total time required / Total available working time

= 23,883.49 hours / 6,000 hours/year

≈ 3.98

Therefore, the new plant would require 4 forging cells.

B. Proportion of time spent in setup = 2,310 hours / 22,928.55 hours ≈ 0.1007
