Oxygen combines with nitrogen in the air to form NO at about 2500 celsius.

The enormous energy of lightning breaks nitrogen molecules and enables their atoms to combine with oxygen in the air forming nitrogen oxides. These dissolve in rain, forming nitrates, that are carried to the earth.

At these high temperatures, nitrogen and oxygen from the air combine to produce nitrogen monoxide. One nitrogen molecule (N2) reacts with one oxygen molecule (O2) to make two nitrogen monoxide molecules (NO).

(a) Magnetizing force = 149.25 AT/m. (b) Total flux in the iron = 3.0156 * \(10^{-4\) Wb. (c) Reluctance of the ring = 4.98 * \(10^3\)AT/Wb.

A magnetic field is a vector field that describes the magnetic force experienced by a moving electric charge in the presence of a magnet, an electric current, or a changing electric field. It is generated by the motion of electric charges (the magnetic moments of elementary particles) and by the intrinsic magnetism of certain fundamental particles that comprise matter. Magnetic fields are used in a variety of applications, from magnetic storage devices like hard drives and credit cards to medical imaging machines like MRI scanners.

The solution to the given problem:Given parameters are:

N= 500 turns

R = 20 ΩU = 24

Vd = 50 cmA = 4 cm2

Relative permeability of iron is 800

(a) Calculation of MMF of the coil:

The MMF (magneto-motive force) of a coil is given as,

N*I

Where,N = Number of turns

I = Current flowing through the coil

Therefore, MMF = N * I = 500 * (24 / 20) = 600 A-T

(b) Calculation of magnetizing force:

First, we will calculate the magnetic field intensity at the center of the coil using the given formula:H = NI / (2r)where,N = Number of turns

I = Current flowing through the coil

r = radius of the coil (mean circumference / 2 * π)H = 500 * (24 / 20) / (2 * 0.79577) = 298.49 A/m

Now, the magnetizing force can be calculated as,F = H * l

where,l = length of the magnetic pathF = 298.49 * (50 / 100) = 149.25 AT/m(c) Calculation of total flux in the iron:Total flux (Φ) in the iron is given as,Φ = B * A where

,B = magnetic field intensityA = area of the cross-section of the ironTherefore, we need to calculate the magnetic field intensity inside the iron first.Using the given parameters, we can calculate the magnetic field inside the iron as,B = μr * μ0 * H

where,μr = Relative permeability of iron = 800μ0 = Permeability of free space = 4 * π * 10^-7T * m/AH = Magnetic field intensity = 298.49 A/mPutting all the values in the formula,B = 800 * 4 * π * 10^-7 * 298.49 = 0.7539 TTherefore,Φ = 0.7539 * 4 * 10^-4 = 3.0156 * 10^-4 Wb(d) Calculation of reluctance of the ring:The reluctance (R) of the iron ring is given as,R = l / (μr * μ0 * A)

where,l = length of the magnetic pathμr = Relative permeability of ironμ0 = Permeability of free spaceA = area of the cross-section of the ironPutting the values in the formula,R = (50 / 100) / (800 * 4 * π * 10^-7 * 4 * 10^-4) = 4.98 * 10^3 AT/WbAnswer:MMF of the coil = 600 A-T

Magnetizing force = 149.25 AT/m

Total flux in the iron = 3.0156 * \(10^{-4\) Wb

Reluctance of the ring = 4.98 * \(10^3\)AT/Wb

The C program uses the exponential McLaurin expansion to calculate an approximate value of e (exp(1)) with at least 10 digits below the decimal point. It iteratively calculates the terms of the expansion and outputs the result.

To calculate the approximate value of e using the exponential McLaurin expansion, we can create a C program that iterates through the terms of the expansion until a desired level of precision is achieved. Here's an example program:

#include <stdio.h>

double calculateExp() {

   double x = 1.0;  // Set x value to 1 for e = exp(1)

   double result = 1.0;

   double term = 1.0;

   int i;

   for (i = 1; i <= 15; i++) {

       term *= x / i;

       result += term;

   }

   return result;

}

int main() {

   double e = calculateExp();

   printf("Approximate value of e: %.10lf\n", e);

   return 0;

}

In this program, the function `calculateExp()` performs the iterative calculation of the exponential McLaurin expansion up to the 15th term. The variable `x` is set to 1 to calculate e = exp(1). The terms are calculated and added to the `result` variable, which stores the approximate value of e. The program then outputs the result with at least 10 digits below the decimal point using the `printf` statement.

By executing this program, you will obtain an approximate value of e with a desired level of precision, displaying at least 10 digits below the decimal point.

Answer:

There are three common methods of charging a battery; constant voltage, constant current and a combination of constant voltage/constant current with or without a smart charging circuit.

Constant voltage allows the full current of the charger to flow into the battery until the power supply reaches its pre-set voltage.  The current will then taper down to a minimum value once that voltage level is reached.  The battery can be left connected to the charger until ready for use and will remain at that “float voltage”, trickle charging to compensate for normal battery self-discharge.

Constant current is a simple form of charging batteries, with the current level set at approximately 10% of the maximum battery rating.  Charge times are relatively long with the disadvantage that the battery may overheat if it is over-charged, leading to premature battery replacement.  This method is suitable for Ni-MH type of batteries.  The battery must be disconnected, or a timer function used once charged.

Constant voltage / constant current (CVCC) is a combination of the above two methods.  The charger limits the amount of current to a pre-set level until the battery reaches a pre-set voltage level.  The current then reduces as the battery becomes fully charged.  The lead acid battery uses the constant current constant voltage (CC/CV) charge method. A regulated current raises the terminal voltage until the upper charge voltage limit is reached, at which point the current drops due to saturation.

the following RAID volume types provide fault tolerance in the event of a single storage device failure is b. striping with parity and c. mirroring

RAID, or "Redundant Arrays of Independent Disks", is a technique that combines multiple disks instead of using a single disk to improve performance, data redundancy, or both. The term was coined in 1987 by David Patterson, Garth A. Gibson, and Randy Katz at the University of California, Berkeley.

While data redundancy provides additional storage space, it also contributes to hard drive reliability. This means that if your hard drive fails, if the same data is also backed up on another hard drive, you can retrieve the data and continue working. On the other hand, without RAID technology, the loss of one disk can affect the entire data if the data is only spread across multiple disks.

Answer: Nuclear to thermal to mechanical to electrical.

Explanation:

Nuclear energy is also referred to as atomic energy which will then lead to the generation of the thermal energy. It should be noted that the thermal energy is also referred to as the heat energy and this is due to the rise in temperature which results in the faster movement of atoms and their collision with one another.

This in turn, brings about the mechanical energy which is simply the energy caused by the motion and this in turn, also lead to electrical energy.

Therefore, the correct answer is Nuclear to thermal to mechanical to electrical.

The thickness of aluminium needed to stop the beam electrons, protons and alpha particles at the given dfferent kinetic energies is 1.5 x 10⁻¹⁴ m.

The thickness of the aluminum can be determined using from distance of closest approach of the particle.

\(K.E = \frac{2KZe^2}{r}\)

where;

\(r = \frac{2KZe^2}{K.E} \\\\r = \frac{2 \times 9\times 10^9 \times 13\times (1.6\times 10^{-19})^2}{2.5 \times 10^6 \times 1.6 \times 10^{-19}} \\\\r = 1.5 \times 10^{-14} \ m\)

Since the magnitude of charge of electron and proton is the same, at equal kinetic energy, the thickness will be same. r = 1.5 x 10⁻¹⁴ m.

Charge of alpah particle = 2e

\(r = \frac{2KZe^2}{K.E} \\\\r = \frac{2 \times 9\times 10^9 \times 13\times (2 \times 1.6\times 10^{-19})^2}{10 \times 10^6 \times 1.6 \times 10^{-19}} \\\\r = 1.5 \times 10^{-14} \ m\)

It always serves a clear and well-defined goal. Experiments may be conducted to better understand the problem (or a potential solution), but the purpose of engineering design is always to solve a problem.

The engineering design approach enables students to learn from failure and stresses open-ended problem solutions. This technique develops students' capacity to devise creative answers to problems in any discipline.
