Answer:

a) 19.44 ohm

b) 5.14 A

c) 51.9° lagging

Explanation:

A series RLC circuit containing a resistance of 12Ω, an inductive reactance of 47.13 Ω and a capacitive reactance of 31.83 Ω are connected in series across a 100V, 50Hz supply. Calculate the total circuit impedance, the circuits current, power factor

Given that:

R = 12 Ω, \(X_L=47.13\ ohm,\ X_C=31.83 \ ohm\), f = 50 Hz,  

A) Total circuit impedance (Z) is given by:

\(Z=\sqrt{R^2+(X_L-X_C)^2} =\sqrt{12^2+(47.13^2-31.83)^2} =\sqrt{378.09} =19.44\ ohm\)

B) the circuits current (I) is given by:

\(I=\frac{V}{Z}=\frac{100}{19.44}=5.14\ A\)

The voltage across the resistor (\(V_R\)) = IR= 5.14 × 12 = 61.68 V

The voltage across the inductor (\(V_L\)) = \(IX_L\) = 5.14 × 47.13 = 242.25 V

The voltage across the capacitor (\(V_c\)) = \(IX_C\) = 5.14 × 31.83 = 163.5 V

C) The power factor (Θ) is calculated as:

\(cos(\theta)=\frac{R}{Z}\\cos(\theta)=\frac{12}{19.44} =0.619\\\theta=cos^{-1}(0.6172)\\\theta=51.9^o\ laggin\)

Answer: In combustion engines, fuel and oxidizer (usually air or oxygen) are reacted and combusted in a closed combustion chamber. In a combustion process, the hot gases at high temperatures and pressures are produced. Because of the expansion of the hot gases, the engine's moving parts are moving and doing mechanical work.

Explanation:

Answer: Fire

! HOW DOES AN INTERNAL COMBUSTION ENGINE WORK?

Combustion, also known as burning, is the basic chemical process of releasing energy from a fuel and air mixture.  In an internal combustion engine (ICE), the ignition and combustion of the fuel occurs within the engine itself. The engine then partially converts the energy from the combustion to work. The engine consists of a fixed cylinder and a moving piston. The expanding combustion gases push the piston, which in turn rotates the crankshaft. Ultimately, through a system of gears in the powertrain, this motion drives the vehicle’s wheels.

There are two kinds of internal combustion engines currently in production: the spark ignition gasoline engine and the compression ignition diesel engine. Most of these are four-stroke cycle engines, meaning four piston strokes are needed to complete a cycle. The cycle includes four distinct processes: intake, compression, combustion and power stroke, and exhaust.

Spark ignition gasoline and compression ignition diesel engines differ in how they supply and ignite the fuel.  In a spark ignition engine, the fuel is mixed with air and then inducted into the cylinder during the intake process. After the piston compresses the fuel-air mixture, the spark ignites it, causing combustion. The expansion of the combustion gases pushes the piston during the power stroke. In a diesel engine, only air is inducted into the engine and then compressed. Diesel engines then spray the fuel into the hot compressed air at a suitable, measured rate, causing it to ignite.

Horizontal shapes are simply defined as shapes that identified by their alignment and orientation along the horizontal axis.

Horizontal shapes are simply identified by their alignment and orientation along the horizontal axis.

These shapes appear to be extended in a left-to-right or right-to-left direction, with a greater width-to-height ratio. Rectangles, squares, lines, and strips are typical examples.

While lines are one-dimensional, horizontal objects with an unlimited length, rectangles and squares have four sides and have horizontal top and bottom boundaries. Strips are lengthy, varying-width horizontal shapes that are frequently utilized in design and the arts.

Horizontal shapes can imply security, harmony, calmness, and a sense of rootedness.
