what is the third most abundant component of dry air?

Hai

Your answer will be A.

If you lower the Air Pressure your Object will Float Down ward. The Air Pressure allows it to Fly.

The pressure field created by faster air movement over an airfoil is; A:  higher

When the air hits the front of the wing, the air will flow in a steeper curve upward, than the bottom wing flow which will lead to the creation of a vacuum on top of the wing that pulls more air towards the top of the wing.

Finally, this air above does the same thing but it will move faster as a result of the vacuum pulling it in, and as such the vacuum now lifts the wing. Thus, Faster air movement over an airfoil creates a higher pressure field.

In the CGS system, the unit of charge is the charging unit (ESU). Also known as "Statistical Pendant" (StatC). In the CGS system, the load unit is the electromagnetic unit (E.M.E.).

The e.s.u. of charge, also known as franklin or statcoulomb, is the charge such that two similar q=1statC charges at a space of 1cm from each other exert an electrostatic force of 1dyn on each other.

The e.m.u. of current, also called the biot or abampere, is the current such that two infinitely-long straight, parallel conductors carrying 1abA of current and separated by 1cm exert a magnetostatic force of 2dyn on each other.

The relations between these units are such that

\(\frac{1 statC}{1 abA * 1s} = \frac{1 statC}{1abC} = \frac{1}{C} = \frac{1 statA}{1abA} = \frac{\frac{1 statC}{s} } {1 abA}\)

where c is the speed of light.

The ESU and EMU systems of electromagnetic units are different and they should generally be considered separate and independent (if relatively similar), and they do not coincide with the gaussian set of electromagnetic units.

For example, since the electrical displacement vector D is defined as \(E + 4\pi P\) in the ESU system and \(\frac{1}{c^{2} } E + 4\pi P\) the EMU system, it is not possible to exchange the formulas of one system for another without using a formula dictionary like the one at Jackson's end.

The electricity production from the incinerator per day at it full capacity is 1950 MWh / day

Q = 10, 000 tonnes / day

Capacity of incinerator = 3000 tonnes / day

I tonne = looo kg

Low Heating Value of MSW = LHV = 13, 600 K J / kg

Efficiency of incinerator for electricity generation = 0 .18

Electricity production from incinerator per day at full capacity

LHV x full capacity x efficiency

= 13, 000 KJ/kg x /3000 x 1000 kg* 0 . 18 *1 MWh/3.6 * 106 KJ

1MWh = 3600000 KJ=> IKJ =1 MWh/3. 6 * 10⁶

RAM is called “random access” because any storage location on the computer can be accessed directly (as opposed to randomly).

In a three-point bending test on a circular MgO specimen, the minimum possible radius without fracture can be computed based on the applied load, flexural strength, and separation between load points.

Given an applied load of 1500 N (337 lbf), a flexural strength of 105 MPa (15,000 psi), and a separation between load points of 50.0 mm (1.97 in), we can calculate the minimum radius of the specimen.

In three-point bending, the maximum tensile stress occurs at the surface of the specimen, farthest from the neutral axis. To calculate the minimum radius without fracture, we can use the formula for bending stress:

σ = (M × c) / I

Where σ is the bending stress, M is the applied moment, c is the distance from the neutral axis to the surface, and I is the moment of inertia of the circular cross-section.

To find the minimum radius, we need to determine the distance c. In three-point bending, c is equal to half the separation between the load points. So c = 50.0 mm / 2 = 25.0 mm (0.984 in).

Given the applied load of 1500 N and the flexural strength of 105 MPa, we can rearrange the formula to solve for the moment M:

M = (σ × I) / c

The moment of inertia I for a circular cross-section is equal to (π × r^4) / 4, where r is the radius of the specimen.

Substituting the values into the equation, we can solve for the minimum radius:

1500 N = (105 MPa × (π × r^4) / 4) / 25.0 mm

Simplifying the equation, we can solve for r, which will give us the minimum radius of the MgO specimen without fracture.

It is to be noted that Electrical Resistance Welding comprises a welding head that exerts pressure and holds the metal between its electrodes, as well as a welding power source that applies electric current to the metal to be welded. When force is exerted, resistance creates friction heat.

A weld is a metal coalescence formed by heating to an appropriate temperature with or without pressure, and with or without the introduction of a filler substance.

Resistance welding bonds are classified into three types:

The actual electric power generation is approximately 482,941.97 kW.

a. To determine the mechanical energy of air per unit mass and the power generation potential of a wind turbine with 80-m-diameter blades, we can use the following formulas:

1. Mechanical Energy of Air per Unit Mass:

The mechanical energy of air per unit mass (E) is given by:

E = (1/2) * V^2

- E is the mechanical energy per unit mass (kJ/kg)

- V is the wind speed (m/s)

Substituting the given wind speed of 16 m/s into the formula, we have:

E = (1/2) * (16^2) = 128 kJ/kg

2. Power Generation Potential of the Wind Turbine:

The power generation potential (P) of the wind turbine can be calculated using the formula:

P = (1/2) * ρ * A * V^3

- P is the power generation potential (kW)

- ρ is the air density (kg/m^3)

- A is the swept area of the turbine blades (m^2)

- V is the wind speed (m/s)

The swept area (A) of the turbine blades can be calculated using the diameter (D) of the blades:

A = (π/4) * D^2

Substituting the given diameter of 80 m into the formula, we have:

A = (π/4) * (80^2) = 5026.548 m^2

Now we can calculate the power generation potential:

P = (1/2) * (1.25 kg/m^3) * (5026.548 m^2) * (16^3) = 1,609,806.55 kW

b. To determine the actual electric power generation, assuming an overall efficiency of 30 percent, we can multiply the power generation potential (P) by the efficiency factor:

Actual Electric Power Generation = Efficiency * Power Generation Potential

Actual Electric Power Generation = 0.30 * 1,609,806.55 kW = 482,941.97 kW

The average cost per share is $0.0031 per share

To calculate the average cost, divide the total purchase amount by the number of shares purchased to figure the average cost per share.

The average cost share method is commonly used by investors for mutual fund tax reporting.

Therefore average cost per share = Total cost/ total share owned.For example, an investor that has $1000in an investment and owns 500 shares would have an average cost basis of $2 i.e ($10,00 / 500).

Similarly,The total cost =$ 2.80+ $1.90 = $4.70

The total share owned = 500+ 1000 = 1500

average cost = 4.70/1500 = $0.0031 per share.

The lift coefficient for each airfoil can be found by using the single vortex method. For a uniform stream with speed V1 at an angle of attack alpha.

A biplane with flat plate airfoils of chord c at a distance h apart, the lift coefficient can be calculated by dividing the total vortex strength by the product of the velocity and the reference area.

The lift coefficient represents the lift generated by an airfoil relative to its size and the flow conditions. In this case, we can use the single vortex method, which simplifies the flow field by representing each airfoil as a single vortex. To find the lift coefficient for each airfoil, we need to calculate the total vortex strength (Γ) for each vortex, and then divide it by the product of the velocity (V1) and the reference area (c). The reference area is the area over which the lift force is evaluated, and in this case, it is the airfoil chord (c). By dividing the total vortex strength by the velocity and reference area, we obtain the lift coefficient for each airfoil.
