What is the name of the device fitted underneath the rear bumper on some cars for either purposes of appearance or to increase aerodynamic performance

Where the above conditions are ogiven, the power required for a single inhalation is approximately 0.00141 W.

To estimate the power required for a single inhalation, we need to calculate the force and velocity of the air flowing through the trachea.

Assumptions:

We assume that the air can be treated as an incompressible fluid.

We assume that the air flow is laminar.

We assume that the trachea is a straight pipe with a constant diameter of 10 mm (since the cross-sectional area is 125 mm^2).

We neglect any frictional losses due to the presence of the walls of the trachea.

First, let's calculate the velocity of the air. We know that the tidal volume is 0.5 liters, which is equivalent to 500 ml or 0.0005 m^3. This volume is breathed in within 1.5 seconds, so the flow rate of air through the trachea is:

Q = V/t = 0.0005 m^3 / 1.5 s = 0.000333 m^3/s

The cross-sectional area of the trachea is 125 mm^2, which is equivalent to 0.000125 m^2. Using the continuity equation for incompressible fluids, we can relate the flow rate of air to its velocity:

Q = A x v

where A is the cross-sectional area of the trachea and v is the velocity of the air. Solving for v, we get:

v = Q/A = 0.000333 m^3/s / 0.000125 m^2 = 2.664 m/s

Now that we have the velocity, we can calculate the force of the air using the equation:

F = ρ x A x v^2 / 2

where ρ is the density of air, which we can assume to be 1.2 kg/m^3 (at standard conditions of temperature and pressure). Substituting the values, we get:

F = 1.2 kg/m^3 x 0.000125 m^2 x (2.664 m/s)^2 / 2 = 0.000530 N

Finally, we can calculate the power required for a single inhalation using the equation:

Power = Force x Velocity

Substituting the values, we get:

Power = 0.000530 N x 2.664 m/s = 0.00141 W

Therefore, the power required for a single inhalation is approximately 0.00141 W.

D. Electric meter

Explanation:

An electric meter is a metering device that is used for the measurement of the electric power consumption of an electrical powered tools, a living space or a building

Electric meter readings are used by electric utility company to sell electric power to consumers at a given rate such that it allows the electric utility company to receive payment for the total power supplied, and for the consumer to regulate the amount of power consumed

The electric meters are usually calibrated in kilowatt hour (kWh) and prepaid meter displays the amount of units of power bought, while post paid meters are usually read once each billing period which is usually one month.

Answer:

Because the equivalent or the total resistance is lower comparatively.

Explanation:

It is because in parallel circuit, the equivalent resistance or the total resistance is lower comparatively and hence more current flow through the circuit.

Basically, the same resistors connected in series have high values as compared to the scenario when these resistors are connected in parallel.

Answer:

Safety valves are part of the safety features placed in the system to prevent the system from experiencing over pressures

Explanation:

A safety valve is a valve that is actuated automatically when the pressure on the inlet portion rises to a specified value to allow the outflow or discharge of fluid such as liquid, steam or gas out of the system to prevent the system pressure limit from being exceeded. The design of safety valves is such that the valve closes the emergency outlet  port again once the system pressure returns to normal.

Based on the calculations, the length of the box must be equal to 24 inches.

Given the following data:

This article provides the standard requirement and dimensions for the installation and use of all electrical boxes and conduit bodies that are used as pull boxes, outlet, junction, etc.

Basically, electrical boxes that contain straight pulls are typically sized based on the largest single raceway which enters the box. Also, you should multiply the trade size of the largest raceway by eight (8) when calculating the minimum length of an electrical box containing straight pull in accordance with Article [314.28(A)(1)] of the National Electrical Code (NEC).

For the minimum length:

\(Length = 3 \times 8\)

Answer:

the diameter of the Sun is approximately 1.392 million kilometers.

Explanation:

To find the diameter of the Sun, we can use the formula:

diameter = 2 x distance x tan(angle/2)

where distance is the distance between the Sun and the Earth, angle is the subtended angle of the Sun, and tan is the tangent function.

Substituting the values given, we get:

diameter = 2 x 150000000 km x tan(32'/2)

diameter ≈ 1.392 x 10^6 km

Therefore, the diameter of the Sun is approximately 1.392 million kilometers.

They are expensive, time-consuming to make, the needing to be rebuilt if destroyed, and sometimes it is impossible to build a large enough model

Explanation:

They are costly, labor-intensive to manufacture, must be rebuilt if they are destroyed, and occasionally it is impossible to construct a large enough model.

An automaton is a relatively self-operating machine or control system designed to perform a series of tasks automatically or respond to preset commands.

The bell strikers in mechanical clocks are an example of an automaton that, to the uneducated eye, appears to be propelled by its own volition.

The expression has a long history of use to describe automata that move like real, breathing people or animals and are created to entertain or impress people.

Therefore, they are expensive to produce, labor-intensive to rebuild if they are destroyed, and occasionally impossible to build a large enough model.

Explanation:

We can see here that the law of resistivity, also known as Ohm's law, states that the electrical resistance of a conductor is directly proportional to its resistivity and length, and inversely proportional to its cross-sectional area.

The Law of resistivity can be mathematically represented as:

R = ρ × (L / A)

Where:

R is the electrical resistance of the conductor,

ρ (rho) is the resistivity of the material,

L is the length of the conductor, and

A is the cross-sectional area of the conductor.

The resistivity (ρ) is a characteristic property of a material that quantifies its ability to resist the flow of electric current. It depends on the nature of the material, its temperature, and sometimes its purity. Resistivity is measured in ohm-meters (Ω·m).

Answer:

The line voltage of the three phase network is 346.41 V

Explanation:

Star Connected Load

Resistance, R₁ = R₂ = R₃ = 18 Ω

For a star connected load, the line current = the phase current, that is we have

\(I_L = 25 \, A = I_{Ph}\)

Whereby the the voltage across each resistance = \(V_R\) is given by the relation;

\(V_R\) = \(I_{Ph}\) × R

Hence;

\(V_{Ph}\) = \(V_R\) = \(I_{Ph}\) × R  = 25 × 8 = 200 V

Therefore we have;

The line voltage, \(V_{L}\) = √3 × \(V_{Ph}\) = √3 × 200 = 346.41 V.

Hence, the line voltage of the three phase network = 346.41 V.

The general form of the capacitor voltage for the electrical network shown in Figure P4.4 is V(t) = 1/2^e^-10^tsin20t

A capacitor is an electronic component that stores electrical energy in an electric field. It is typically made up of two conductive plates separated by a non-conductive material, or dielectric.

When a voltage is applied across the plates, an electric field is created between them, which causes a build-up of electric charge on the plates. The amount of charge that can be stored on the plates depends on the capacitance of the capacitor, which is determined by the size and spacing of the plates, as well as the type of dielectric material used.

Answer:

Larger

Explanation:

When a vehicle is accelerated, the weight of the vehicle and the driver is transferred to the front of the  rear of the car.

This transferred weight is nothing but the  additional weight that presses the car's suspension in the downward direction thereby affecting tire contact patch in the rear due to which the rear tires loses adhesion.

When you accelerate, the size of the front tire patch becomes larger.

It should be noted that to develop the power to accelerate quickly, an internal combustion engine is vital. When a vehicle is accelerated, the weight of the vehicle and that of the driver will be transferred to the front of the vehicle.

Therefore, when you accelerate, the size of the front tire patch becomes larger since the transferred weight is additional weight.
