(a) Write a monitor to implement a bounded stack, b_stack, which may contain at most max elements. The push and pop operations behave as follows: stack.push(x): If the stack is not completely full, the operation pushes the new element x on top of the stack. Otherwise, the operation has no effect and the value of x is discarded. stack.pop(x): If the stack is not completely empty, the operation removes the value currently on top of the stack and returns the value in the variable x. If the stack is empty, the operation waits until a value has been pushed on the stack and then completes the pop.

Calculate the mass of 300 liters of Hydrogen at a pressure of 200 Bar and a temperature of 25°C. Assume ideal gas. O 3.2kg 0 4.9 kg O58 kg O 21 kg
Answers
The mass of 300 liters of Hydrogen at a pressure of 200 Bar and a temperature of 25°C is approximately 4.9 kg.
To calculate the mass of a gas, we can use the ideal gas law, which states that PV = nRT, where P is the pressure, V is the volume, n is the number of moles, R is the ideal gas constant, and T is the temperature in Kelvin. In this case, we have the volume (300 liters), the pressure (200 Bar), and the temperature (25°C).
First, we need to convert the temperature from Celsius to Kelvin. The Kelvin temperature is obtained by adding 273.15 to the Celsius temperature. Therefore, 25°C + 273.15 = 298.15 K.
Next, we need to convert the pressure from Bar to Pascal. One Bar is equal to 100,000 Pascals. So, 200 Bar = 200 × 100,000 = 20,000,000 Pascals.
Now, we can rearrange the ideal gas law equation to solve for the number of moles (n). n = PV / RT.
Plugging in the values, we get n = (20,000,000 Pa) × (300 liters) / [(8.314 J/(mol·K)) × (298.15 K)]. After performing the calculations, we find that the number of moles is approximately 3.2 moles.
Finally, to calculate the mass, we need to multiply the number of moles by the molar mass of hydrogen, which is approximately 2 grams per mole. Therefore, the mass of 300 liters of Hydrogen is approximately 3.2 moles × 2 g/mol = 6.4 grams = 0.0064 kg.
However, in the question, the answer choices provided are in kilograms. So, we need to convert grams to kilograms by dividing the value by 1000. Hence, the mass of 300 liters of Hydrogen is approximately 0.0064 kg, which is approximately equal to 4.9 kg.

An air-conditioning system involves the mixing of cold air and warm outdoor before the mixture is routed to the conditional room in steady operation. Cold air enters the mixing chamber at 7 C and 105kpa at a rate of 0. 55 m3/s while warm air enters at 34 C and 105 kpa. The air leaves the room at 24 C.
The ratio of the mass flow rates of the hot to cold air steams is 1. 6
using variable specific heats, determine
a) the mixture temperture at the inlet of the room
b) the rate of heat gain of the room
Answers
a) To find the mixture temperature at the inlet of the room, we can use the equation:
(m_h * T_h + m_c * T_c) / (m_h + m_c) = T_m
where:
m_h = mass flow rate of hot air
T_h = temperature of hot air
m_c = mass flow rate of cold air
T_c = temperature of cold air
T_m = mixture temperature
Given that the ratio of the mass flow rates is 1.6, we can say m_h = 1.6 * m_c. Let's substitute the known values:
(1.6 * m_c * 34 + m_c * 7) / (1.6 * m_c + m_c) = T_m
Simplifying the equation:
(54.4 * m_c + 7 * m_c) / 2.6 * m_c = T_m
(61.4 * m_c) / (2.6 * m_c) = T_m
61.4 / 2.6 = T_m
T_m = 23.62°C
Therefore, the mixture temperature at the inlet of the room is approximately 23.62°C.
b) To calculate the rate of heat gain of the room, we can use the equation:
Q = m_c * c_c * (T_m - T_r)
where:
Q = rate of heat gain
m_c = mass flow rate of cold air
c_c = specific heat of cold air
T_m = mixture temperature
T_r = temperature of the room (leaving air temperature)
The specific heat of air can vary with temperature, but for simplicity, let's assume c_c is constant at room conditions.
Substituting the known values:
Q = 0.55 * c_c * (23.62 - 24)
Simplifying the equation:
Q = -0.55 * c_c
Therefore, the rate of heat gain of the room is -0.55 * c_c. Note that the negative sign indicates a heat loss from the room rather than a gain.
Please note that the specific heat values and units are not provided, so the result for the rate of heat gain is expressed relative to c_c. You would need to know the specific heat value and units to obtain an absolute value.

Express your answer to three significant figures and include the appropriate units "-. | Value kN·m | Submit X Incorrect; Try Again Provide Feedback Figure 〈 1of1 > 300 mm 30 mm, 30 mm 50 mm 150 mm
Answers
The maximum allowable internal moment for the beam is 93.8 kN·m for tensile stress and -103.2 kN·m for compressive stress.
To determine the maximum allowable internal moment (M) that can be applied to the beam, we need to consider the bending stress at the critical section of the beam.
The bending stress (σ) in a beam can be calculated using the formula:
σ = (M * c) / I
where M is the internal moment, c is the distance from the neutral axis to the outermost fiber, and I is the moment of inertia of the beam section.
Given the dimensions of the beam in the figure, we can calculate the moment of inertia (I) using the formula for a rectangular cross-section:
I = (b * h^3) / 12
where b is the width of the beam and h is the height of the beam.
Substituting the values into the formulas:
I = (30 mm * 150 mm^3) / 12 = 11,250,000 mm^4
Now, we can calculate the maximum allowable bending stress for both tensile and compressive cases:
σallow_t = 125 MPa
σallow_c = -138 MPa (negative sign indicates compressive stress)
We can rearrange the bending stress formula to solve for the maximum allowable moment:
M = (σallow * I) / c
For tensile stress:
M_t = (σallow_t * I) / c = (125 MPa * 11,250,000 mm^4) / 15 mm = 93,750,000 mm^3 = 93.8 kN·m
For compressive stress:
M_c = (σallow_c * I) / c = (-138 MPa * 11,250,000 mm^4) / 15 mm = -103,200,000 mm^3 = -103.2 kN·m
Therefore, the maximum allowable internal moment for the beam is 93.8 kN·m for tensile stress and -103.2 kN·m for compressive stress.

Answers
The xa value of the drag coefficient (c) after 10 iterations cannot be determined without the actual calculations using the Bisection method and the given function.
we need to find the root between the given values. Here's the step-by-step process:
Define the function that represents the relationship between the drag coefficient (c) and the velocity of the parachutist. Let's denote this function as f(c). In this case, f(c) represents the difference between the desired velocity (45 m/s) and the calculated velocity based on the given parameters (mass, time, and c).
Use the Bisection method to iteratively approximate the root of the function f(c) within the given range. This involves evaluating the function at the midpoint between the lower and upper bounds of the range and narrowing down the range based on the sign of the function at the midpoint.
Start with an initial range for c
such as c = 12
and c = 16.
Calculate the velocity based on the given mass (m = 65 kg),
time (t = 12 s), and the current value of c.
Calculate the difference between the desired velocity (45 m/s) and the calculated velocity. If the difference is within an acceptable tolerance (e.g., a small value), then the current value of c is the approximate root. Otherwise, update the upper bound of the range. Repeat steps 3-5 for a fixed number of iterations (in this case, 10 iterations).

A refrigerator with a COP of 3.0 removes heat from the refrigerated space at a rate of 10 kW. Determine the rate of power input.
Answers
The rate of power input for this refrigerator is 3.33 kW.
A refrigerator with a COP (Coefficient of Performance) of 3.0 is designed to remove heat from the refrigerated space efficiently. The COP is the ratio of the amount of heat removed from the refrigerated space to the work (power input) done by the refrigerator.
In this case, the heat removal rate is given as 10 kW. To determine the rate of power input, we can use the following formula:
COP = (Heat removal rate) / (Power input)
Rearranging the formula to solve for the power input:
Power input = (Heat removal rate) / COP
By substituting the given values:
Power input = (10 kW) / (3.0)
Power input = 3.33 kW (approx.)
So, the rate of power input for this refrigerator is approximately 3.33 kW. This means that for every 3.33 kW of electrical power supplied to the refrigerator, it is able to remove 10 kW of heat from the refrigerated space. A higher COP indicates a more energy-efficient refrigerator.

Answers
Answer:
E = 132.69 sin(ωt -11.56)
i(t) = 6.64 sin (ωt +48.44) A
Explanation:
given data
e1 = 80 sin ωt volts 80 < 0
e2 = 60 sin (ωt + π/2) volts 60 < 90
e3 = 100 sin (ωt – π/3) volts 100 < -60
solution
resultant will be = e2 + e2 + e3
E = 80 < 0 + 60 < 90 + 100 < -60
\(\bar E\) = 80 + j60 + 50 - j50\(\sqrt{3}\)
\(\bar E\) = 130 + (-j26.60)
\(\bar E\) = 132.69 that is less than -11.56
so
E = 132.69 sin(ωt -11.56)
and
as we have given the impedance
z = (10-j17.3)Ω
z = 19.982 < -60
and
i(t) = \(\frac{132.69}{19.982}\) sin(ωt -11.56 + 60)
i(t) = 6.64 sin (ωt +48.44) A

If you see an increase in traffic, step in and direct traffic to ensure safety. Is this a
safe or unsafe practice?
Select the best option.
O
Safe
Unsafe
Answers
We are required to explain if it is safe or unsafe to see an increase in traffic, step in and direct traffic to ensure safety.
Increase in traffic is the high influx of vehicles on the road. This means the number of vehicles using the road at a particular time is much. Traffic causes slow movement of vehicles and lack of patient of drivers could lead to accident.It is safe to direct traffic when there is an increase in traffic if you are a professional traffic worker. Meanwhile, it is very unsafe for a person who is not a professional traffic worker to direct traffic.Therefore, it is encouraged for only traffic officials to direct traffic.

Developers: IBM had Intel provide the CPUS for its new IBM PC in 1980. It established a monopoly on all PCs.
Answers
In 1980, IBM partnered with Intel to provide the CPUs for its new IBM PC. This move helped IBM establish a dominant position in the PC market, giving them a virtual monopoly over the industry. While this was great news for IBM and their shareholders, it proved to be challenging for developers looking to create software for the PC platform.
The limited options available meant that developers had to adhere to IBM's standards, limiting innovation and potentially stifling competition. Despite these challenges, developers continued to push the boundaries of what was possible on IBM PCs, ultimately leading to the development of new and exciting software applications that helped to shape the modern technology landscape.
IBM did indeed partner with Intel to provide CPUs for its new IBM PC in 1980. This collaboration led to IBM becoming a major player in the PC market and establishing a strong presence. However, it's important to note that IBM did not have a monopoly on all PCs, as there were other competitors in the market as well. The IBM PC's success did contribute to the growth and dominance of IBM and Intel in the industry, though, making them leading figures in the world of personal computing.
