The number of telephone calls that pass through a switchboard has a mean equal to 2 per minute. The probability that one telephone calls pass through the switchboard in three minutes i
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
Therefore, the probability that one telephone call passes through is approximately 0.0149, or about 1.49%.

when charging a capacitor in a rc circuit, how does the current change with time?
When charging a capacitor in an RC circuit, the current changes with time as it follows an exponential decay pattern.
1. Initially, when the capacitor is fully discharged, the current in the circuit is at its maximum value. This is because the voltage across the capacitor is zero, and according to Ohm's law (I = V/R), the current is maximum when the voltage is minimum.
2. As time passes, the capacitor starts to charge, and the voltage across it increases.
3. As the voltage across the capacitor increases, the potential difference across the resistor decreases, causing the current in the circuit to decrease.
4. The rate of change of the current in the circuit is proportional to the difference between the voltage across the resistor and the capacitor. This means that as the capacitor charges, the rate of decrease of the current in the circuit slows down.
5. Eventually, when the capacitor is fully charged, the current in the circuit drops to zero, as the potential difference across the resistor becomes zero.
So, in summary, when charging a capacitor in an RC circuit, the current changes with time by decreasing from its initial maximum value to zero, following an exponential decay pattern.

the quality.
The thread is crucial for ensuring the quality and durability of the garment. It is formed by spinning and twisting fibers together, creating a continuous strand that is used to hold the various components of the garment together.
The quality of the thread directly affects the overall quality of the garment. A strong and well-constructed thread is essential for providing structural integrity and preventing the garment from unraveling or falling apart over time. It must be able to withstand the stresses and strains that occur during regular use, including stretching, pulling, and washing.
When choosing the appropriate thread for a garment, several factors are considered, including the type of fabric, the intended use of the garment, and the desired aesthetic. Different threads have varying levels of strength, elasticity, and resistance to abrasion. For example, a heavier fabric might require a thicker and more robust thread, while a delicate fabric may require a finer and more delicate thread to prevent damage.
The quality of the thread also relates to its consistency and uniformity. Irregularities in the thread's thickness or tension can result in uneven stitches, which may compromise the appearance and functionality of the garment. In addition, the thread's color and texture should be chosen carefully to complement the fabric and enhance the overall aesthetic appeal.
In the manufacturing process, quality control measures are implemented to ensure that the thread meets the required standards. This involves testing the thread for strength, colorfastness, and resistance to abrasion. By using high-quality thread and maintaining strict quality control, garment manufacturers can ensure that the final product meets or exceeds the expectations of customers in terms of both appearance and durability.
In summary, the thread plays a vital role in holding a garment together and contributes significantly to its quality and longevity.

(20 points) A 1 mm diameter tube is connected to the bottom of a container filled with water to a height of 2 cm from the bottom. Air flows from the tube into the liquid and creates spherical bubbles with diameter about the diameter of the tube (1 mm). Everything is at 298 K. The tube is short but is connected to a much longer 2 m long hose that is 6 mm in diameter. The hose is connected to the gas supply. If there is no gas flow the water will leak into the tube and into the supply hose. When gas flows the water is blocked from entering the tube and bubbling starts. State all assumptions in answering the following questions. (a) What should be the minimum air flow rate and the gas supply pressure to keep the water from leaking back into the tube? (b) Is the flow in the hose laminar or turbulent? Is the flow in the tube laminar or turbulent?
Solution :
Given :
h = 2 cm
Diameter of the tube , d = 1 mm
Diameter of the hose, D = 6 mm
Between 1 and 2, by applying Bernoulli's principle, we get
As point 1 is just below the free surface of liquid, so
\($P_1=P_{atm} \text{ and} \ V_1=0$\)
\($\frac{P_{atm}}{\rho g}+\frac{v_1^2}{2g} +h = \frac{P_2}{\rho g}$\)
\($\frac{101.325}{1000 \times 9.81}+0.02 =\frac{P_2}{\rho g}$\)
\($P_2 = 111.35 \ kPa$\)
Therefore, 111.325 kPa is the gas supply pressure required to keep the water from leaking back into the tube.
Velocity at point 2,
\($V_2=\sqrt{\left(\frac{111.135}{\rho g}+0.02}\right)\times 2g$\)
= 1.617 m/s
Flow of water, \($Q_2 = A_{tube} \times V_2$\)
\($=\frac{\pi}{4} \times (10^{-3})^2 \times 1.617 $\)
\($1.2695 \times 10^{-6} \ m^3/s$\)
Minimum air flow rate,
\($Q_2 = Q_3 = A_{hose} \times V_3$\)
\($V_3 = \frac{Q_2}{\frac{\pi}{4}D^2}$\)
\($V_3 = \frac{1.2695 \times10^{-6}}{\pi\times 0.25 \times 36 \times 10^{-6}}$\)
= 0.0449 m/s
b). Reynolds number in hose,
\($Re = \frac{\rho V_3 D}{\mu} = \frac{V_3 D}{\nu}$\)
υ for water at 25 degree Celsius is \($8.9 \times 10^{-7} \ m^2/s$\)
υ for air at 25 degree Celsius is \($1.562 \times 10^{-5} \ m^2/s$\)
\($Re_{hose}=\frac{0.0449 \times 6 \times 10^{-3}}{1.562 \times 10^{-5}}$\)
= 17.25
Therefore the flow is laminar.
Reynolds number in the pipe
\($Re = \frac{V_2 d}{\nu} = \frac{1.617 \times 10^{-3}}{8.9 \times 10^{-7}}$\)
= 1816.85, which is less than 2000.
So the flow is laminar inside the tube.
A cylindrical specimen of a hypothetical metal alloy is stressed in compression. If its original and final diameters are 20.000 and 20.025 mm, respectively, and its final length is 74.96 mm, compute its original length if the deformation is totally elastic. The elastic and shear moduli for this alloy are 105 GPa and 39.7 GPa, respectively.
Answer:
L = 75.25 mm
Explanation:
First we need to find the lateral strain:
Lateral Strain = Change in Diameter/Original Diameter
Lateral Strain = (20.025 mm - 20 mm)/20 mm
Lateral Strain = 1.25 x 10⁻³
Now, we will find the Poisson's Ratio:
Poisson's Ratio = (E/2G) - 1
where,
E = Elastic Modulus = 105 GPa
G = Shear Modulus = 39.7 GPa
Therefore,
Poisson's Ratio = [(105 GPa)/(2)(39.7 GPa)] - 1
Poisson's Ratio = 0.322
Now, we find longitudinal strain by following formula:
Poisson's Ratio = - Lateral Strain/Longitudinal Strain
Longitudinal Strain = - Lateral Strain/Poisson's Ratio
Longitudinal Strain = - (1.25 x 10⁻³)/0.322
Longitudinal Strain = - 3.87 x 10⁻³
Now, we can fin the original length:
Longitudinal Strain = Change in Length/L
where,
L = Original Length = ?
Therefore,
- 3.87 x 10⁻³ = (74.96 mm - L)/L
(- 3.87 x 10⁻³)(L) + L = 74.96 mm
0.99612 L = 74.96 mm
L = 74.96 mm/0.99612
L = 75.25 mm
An evanescent field at angular frequency w = 10¹5 rad/s is created via total internal reflection at the interface between two different media with refractive index n1 and n2, where n1-4, and n2=2. The incident angle 0₁-80°. We can define the propagation direction of the evanescent field as the x-direction, and the z-direction is normal to the interface between the two media, and therefore the evanescent field wave function can be expressed as Ee(kxx+k₂z-t) (a) Should the incident light come from the medium with n1 or the medium with n2 to undergo total internal reflection? (b) is the evanescent field in the medium with n1 or the medium with n2? (c) Calculate the values for kx and kz in the medium in which the field is evanescent.
The incident light should come from the medium with n2 to undergo total internal reflection.
(a) The incident light should come from the medium with n2 to undergo total internal reflection. Total internal reflection occurs when light travels from a medium with a higher refractive index to a medium with a lower refractive index and the angle of incidence exceeds the critical angle. In this case, since n2 is smaller than n1, the light should originate from the medium with n2 to experience total internal reflection at the interface.
(b) The evanescent field is present in the medium with n1. After total internal reflection, the incident light is completely reflected back into the medium with n1, and it does not propagate into the medium with n2. As a result, the evanescent field is confined to the medium with n1.
(c) To calculate the values of kx and kz in the medium where the field is evanescent, we can use the relationship between the wave vector (k) and the refractive index (n) in each medium. The wave vector in the x-direction (kx) and the wave vector in the z-direction (kz) can be expressed as follows:
kx = (w/c) * n * sin(0₁)
kz = [(w/c)^2 * \(n^2\) - \(kx^2\)]
where:
w = angular frequency of the evanescent field
c = speed of light in vacuum
n = refractive index of the medium
0₁ = angle of incidence
Given:
w = 10¹⁵ rad/s
n1 = 4
n2 = 2
0₁ = 80°
Using the above equations, we can calculate the values of kx and kz in the medium with n1:
kx = (10¹⁵ rad/s / 3x10^8 m/s) * 4 * sin(80°)
kz = [(10¹⁵ rad/s / 3x10^8 m/s) * 4^2 - kx]
After substituting the values and performing the calculations, we can determine the specific values of kx and kz in the medium with n1.

The color commonly used for informational signs is ___________
A. Green
B. Red
C. Yellow
D.Blue
Blue: Signs and labels that provide information about a particular item or location typically use the color blue. It is not required that this information be related to safety.
What is safety color?The regulated or best practice method of using colors for workplace safety purposes is referred to as a "safety color." OSHA and ANSI are two organizations that have established a lot of standards for how to use safety colors correctly.
The basic colors do a great job of making workers aware of any potential dangers in the facility. These signs not only raise awareness, but they also provide employees with the information they require to safeguard themselves in the event of danger. Visual communication can help enforce PPE regulations, follow manufacturing procedures in the workplace, and even stop unauthorized employees from entering restricted areas.
Although numerous agencies and organizations give safety colors various meanings, many of them share significant meanings. This is done with the intention of making sure that standards apply to as many different situations as possible.

In surface mining, stripping ratio or strip ratio refers to the amount of waste (or overburden) that must be removed to release a given ore quantity.
Answer:
the amount of waste that must be removed to release a given quantity
Calculate the power required for heating a 1.5 kg sample of water for 10 minutes in a thermal system. What is the amount of energy required to raise the temperature of the water from 25°C to 60°C ? How much minimum amount of power does the heater have to supply per unit time? Why does the actual power rating of the heater need to be higher than this minimum amount? (The specific heat of water is 4.18 J/g°C .)
*60 points to anyone who can help*
Answer:
Power= Heat energy\ time
heat energy= mc∆T
specific heat of water = 4180
1.5*4180*(60-25)
=219450
time = 10× 60= 600 secs
power = 219450/600
Power= 365.75 Watt
=0.37 KW
Explanation:
the actual has to be bigger because the heater might be required to handle more ...also to accommodate extra energy.
g determine the increase in temperature that will cause the 15 mm diameter aluminum rod to buckle if the wall connection at a is fixed and c acts as a pin.
The aluminum rod will buckle when the temperature increases by a certain amount.
What temperature increase will cause the aluminum rod to buckle?When a metal rod is subjected to temperature changes, it undergoes thermal expansion or contraction. If the rod is constrained at one end (fixed connection) and free to rotate at the other end (pin connection), it can experience buckling when the temperature increases beyond a certain threshold. The critical temperature increase that will cause buckling depends on the material properties of the aluminum rod and its dimensions.
To determine the increase in temperature that will cause the 15 mm diameter aluminum rod to buckle under the given conditions, we need to consider the concept of buckling and its governing equations. Buckling occurs when compressive forces in the rod exceed its critical buckling load, resulting in a lateral deflection or bending.
Key factors influencing the buckling behavior include the length of the rod, its modulus of elasticity, moment of inertia, and the boundary conditions at the rod ends. By analyzing the rod's geometry and applying appropriate equations, it is possible to determine the critical buckling load and subsequently calculate the temperature increase required for buckling.
