What is the syntax / methodology for getting memory from the stack?(write a code fragment)c++ language use to .cpp file format
Answers
To get memory from the stack in C++, you can use the syntax:
int* ptr = new int[size];
This syntax uses the 'new' keyword to dynamically allocate memory from the heap. The pointer 'ptr' points to the first element of the dynamically allocated memory. The 'size' variable determines the number of elements to be allocated. This memory can be accessed using array notation, e.g., ptr[0], ptr[1], etc.
Note that memory allocated using 'new' should be explicitly deallocated using the 'delete' keyword to prevent memory leaks:
delete[ ] ptr;

.If the ILS outer market is inoperative, you may substitute
A- a compass locator or precision radar
B- VOR radials that identify the location
C- Distant measuring equipment (DME)
Answers
If the ILS outer marker is inoperative, you may substitute Distant Measuring Equipment (DME). DME provides distance information by measuring the time it takes for a radio signal to travel from the aircraft to the ground station and back again.
It can be used to determine the distance to the airport, which is necessary for making precise approaches and landings. The other options, a compass locator or precision radar and VOR radials, do not provide the same level of accuracy as DME and are not considered suitable replacements for the ILS outer marker.
A radio signal is a type of electromagnetic radiation used to transmit information through the air. Radio signals are used in a wide range of applications, including broadcasting, telecommunications, navigation, and wireless networking.
Radio signals are generated by a transmitter, which converts an electrical signal into an electromagnetic wave. This wave is then transmitted through the air using an antenna, which converts the electromagnetic wave back into an electrical signal at the receiver.

It is recommended to use a Poisson process to model the number of failures in commercial water
pipes, the estimates of the failure rate are given, in units of failures per 100 km of pipe per day,
Answers
A Poisson process is a statistical model that describes the occurrence of rare events over time or space. It is commonly used to model the number of failures in commercial water pipes.
One of the advantages of using a Poisson process to model the number of failures in commercial water pipes is that it allows for the calculation of the probability of multiple failures occurring within a given time period. For example, if the failure rate is estimated to be 1 failure per 100 km of pipe per day, the probability of two failures occurring in a 24 hour period can be calculated.
In addition, the Poisson process can be used to determine the expected number of failures over a given time period. For example, if the failure rate is estimated to be 1 failure per 100 km of pipe per day, the expected number of failures over a 30-day period would be 30 failures.
In conclusion, the Poisson process is a useful statistical model for estimating the number of failures in commercial water pipes. It allows for the calculation of the probability of multiple failures occurring within a given time period, as well as the expected number of failures over a given time period. However, it is important to consider the assumptions of the model and to be aware of potential sources of variation in the rate of failures over time.

Calculate the frequency (in Hz) of the radiation released by the transition of an electron in a hydrogen atom from the n = 5 level to the n = 3 level. ___ x 10 ___ Hz
Answers
The frequency (in Hz) of the radiation released by the transition of an electron in a hydrogen atom from the n = 5 level to the n = 3 level is 7.68 x 10¹⁴ Hz
The frequency (in Hz) of the radiation released by the transition of an electron in a hydrogen atom can be calculated using the Rydberg formula:
1/λ = R (1/n1² - 1/n2²)
where λ is the wavelength of the radiation,
R is the Rydberg constant (3.29 x 10¹⁵ Hz), and
n1 and n2 are the initial and final energy levels of the electron in the hydrogen atom, respectively.
For the transition from n=5 to n=3, we have:
1/λ = R (1/3² - 1/5²)
1/λ = R (1/9 - 1/25)
1/λ = R (16/225)
λ = 225/16R
λ = 225/(16 x 3.29 x 10¹⁵)
λ ≈ 390.6 nm
The frequency of the radiation can be obtained by using the speed of light (c) and the wavelength (λ):
c = fλ
f = c/λ
f = (2.998 x 10⁸ m/s)/(390.6 x 10⁻⁹ m)
f ≈ 7.68 x 10¹⁴ Hz
Therefore, the frequency is approximately 7.68 x 10¹⁴ Hz.

A reinforced concrete column 600 mm diameter has 6 steel rods of 25 mm embedded in it and carries a load of 800 kN. Find the stresses in steel and concrete. Take E = 200GPa for steel and for concrete, E = 25 GPa. Also find the extension of column due to the load.
Answers
The stresses in steel and concrete are 1,631.29 MPa and 0.2535 MPa respectively.
The extension of column due to the load is 0.0017mm
How do we find the values of stresses?To find the stresses in the steel and concrete, we need to use the principle of stress-strain proportionality. The formula for stress is:
Stress (σ) = Load (P) / Area (A)
The area of the steel rods is:
A = (π/4) * (25 mm)^2 = 490.87 mm^2
The area of the concrete is:
A = (π/4) * (600 mm)^2 = 314,159 mm^2
The stress in the steel is:
σ_steel = P / A = 800 kN / 490.87 mm^2 = 1,631.29 MPa
The stress in the concrete is:
σ_concrete = P / A = 800 kN / 314,159 mm^2 = 0.2535 MPa
To find the extension of the column, we need to use the formula for strain:
Strain (ε) = Extension (ΔL) / Original length (L)
We can use the principle of linear elasticity to find the extension of the column due to the load, which states that:
Stress = Young's modulus * Strain
We can use the formula of stress and strain to find the extension of the column:
ΔL = (PL)/(AE)
L = 600mm, P = 800kN and A =314,159 mm^2
ΔL = (80010^310^-360010^-3)/(314,1592510^9) = 0.0017 mm
So the extension of column due to the load is 0.0017mm

In using semaphores to control access to a critical section, we initialize the semaphore’s counter to 1. What happens if we initialize it to 0? to 2?
Answers
Semaphores are used to control access to a shared resource, such as a critical section, in a concurrent system. The semaphore maintains a counter that represents the number of available resources.
When a process requests access to the shared resource, it must acquire the semaphore, decrement the counter, and release the semaphore when it is done with the resource. This ensures that only one process can access the critical section at a time, preventing race conditions and other synchronization issues.
If we initialize the semaphore's counter to 0, it means that there are no resources available. Any process that tries to acquire the semaphore will block until another process releases the semaphore and increments the counter. This can be useful in cases where we want to ensure that a process waits for a resource to become available before proceeding.

how many access valves are needed to recover the refrigerant on a sealed system with an operating compressor that has a completely restricted capillary tube?
Answers
The number of access valves required to recover refrigerant in a closed system with an operating compressor having a strictly limited capillary tube is one.
A capillary tube is a tube with a very small and thin pointed end made of glass or plastic. Capillary tubes are generally used to take small liquid samples.
The capillary tube works by utilizing the principle of capillary action that occurs in the capillary tube. This principle is the existence of a force, namely surface tension and also an adhesion force that is able to resist the effects of the gravitational force. Therefore, the capillary tube is able to raise a liquid into it without the need to make any effort where we just stick the end of the capillary tube on the surface of the liquid to be taken.

Use the divide-and-conquer integer multiplication algorithm to multiply the two binary integers 10011011 and 10111010.
Answers
The final answer is 1011101103080 by using the divide-and-conquer integer multiplication algorithm to multiply the two binary integers 10011011 and 10111010.
Here is the steps to perform integer multiplication using the divide-and-conquer algorithm:
Split each number into two parts, usually the upper and lower halves. In this case, we would have:10011011 = 100110|11
10111010 = 101110|10
Multiply the two parts:(1) Multiply the two upper halves: 100110 x 101110 = 1011110000100
(2) Multiply the two lower halves: 11 x 10 = 110
(3) Multiply the sum of the two halves:
100110 + 11 = 100121 x 101110 + 10 = 101230
(4) Multiply the middle result: 100121 x 101230 = 1011101002970
Combine the results from step 2 to obtain the final answer:1011110000100 + 1011101002970 + 110 = 1011101103080
