if one cuts a current carrying wire, the flow of electricity will spill out into the air.

The definition of absolute and percentage error allows to find the result for the total error in the pressure measurement is:

      P = ( 1000 ± 2 ) kPa

      ΔP = ±2 kPa

The magnitudes is a quantity that in addition to its value has an error due to the instruments or measurement method used, therefore the correct way to express a value is:

         Magnitude = value ± absolute error

Statistical errors can be expressed in several ways:

In all measurements, the worst case is always taken, that is, all errors go in the same direction.

They indicate the percentage errors due to non-linearity 0.15% and the error due to hysteresis 0.05%. the measurement value is P = 1000 kPa.

Let's look for the absolute errors.

                 \(e_r = \frac{\Delta P}{P} = e%/100\)

                 \(\Delta P = P \ \frac{percentage \ error }{100}\)

 We apply this expression to each type of error.

Non-linearity.

                \(\Delta P_1 = 1000 \ \frac{0.15}{100}\)  

                ΔP₁ = 1.5 kPa

Hysteresis.

                \(\Delta P_2 = 1000 \ \frac{0.05}{100}\)  

                ΔP₂ = 0.5 kPa

The total absolute error in the worst case is the sum of the two errors,

              \(\Delta P_{total} = \Delta P_1 + \Delta P_2\)  

              \(\Delta P_{total}= 1.5 +0.5 \\\Delta P_{total} = 2 kPa\)

The measurement should be given in the following way:

            P = 1000 ± 2 kPa

In conclusion using the definition of absolute and percentage error we can find the result for the total error in the pressure measurement is:

             P = ( 1000 ± 2 ) kPa

             ΔP = ±2 kPa

Explanation:

From the question we are told that:

Frequency selectivity ratio \(R=10\)

AM range 750 kHz to 2600 kHz

Therefore Bandwidth is

 \(B=2100-680\)

 \(B=1420KHZ\)

Generally the equation for The intermediate frequency is mathematically given by

Intermediate frequency=\frac{Bandwidth}{2}

 \(F=\frac{B}{2}\)

 \(F=\frac{1420}{2}\)

 \(F=710KHZ\)

Altitude has a direct effect on the specific endurance for a jet aircraft. As altitude increases, the specific endurance of the aircraft decreases.

The specific endurance of an aircraft refers to the amount of time an aircraft can remain in the air on a given amount of fuel. At higher altitudes, the air is thinner and there is less oxygen, which causes the engines to work harder to maintain the same level of performance. This results in a decrease in the specific endurance of the aircraft. Therefore, to maintain the same specific endurance, the aircraft needs to carry more fuel, which makes it heavier and reduces its performance.

Based on the information given, it appears that the assembly is constructed using slender rods with a mass per unit length of 2 kg/m. This suggests that the rods are lightweight and delicate, which may impact the overall strength and stability of the assembly.

It's important to consider the load-bearing capacity of the rods and how they are connected to one another in order to ensure that the assembly can withstand the intended use and any potential stress or strain.

In physics, the term "strain" refers to the measure of deformation experienced by a material when subjected to external forces or stresses. It is a quantity that describes how much an object changes shape when subjected to an external force.

Strain is often represented by the Greek letter epsilon (ε) and is defined as the ratio of the change in size or shape of an object to its original size or shape. Mathematically, strain is expressed as:

ε = ΔL / L, where ε is the strain, ΔL is the change in length or shape of the object, and L is the original length or shape of the object.

Strain can be categorized into different types based on the nature of deformation:

Strain is a dimensionless quantity and is typically expressed as a decimal or percentage. It provides valuable information about the behavior and mechanical properties of materials under stress, such as elasticity, plasticity, and failure points. Strain is an essential concept in fields like solid mechanics, materials science, engineering, and geophysics, where understanding the response of materials to external forces is crucial.

Every procedure where the velocity varies is referred to as acceleration. There are only two ways to accelerate: changing your speed or changing your direction, or changing both.

The directional speed of an item in motion, as measured by a specific unit of time and observed from a certain point of reference, is what is referred to as velocity.

In kinematics, the area of classical mechanics that deals with the motion of bodies, velocity is a fundamental idea.

A physical vector quantity called velocity must have both a magnitude and a direction in order to be defined.

Speed is a coherent derived unit whose quantity is expressed in terms of meters per second in the SI. It is the scalar absolute value of velocity.

Using ohms law, we can say that Voltage is equivalent to Current times Resistance.  We are given the voltage and the resistance of the circuit, so we simply need to find the current.

V = IR

Solve for I, where V = 2volts and R = 3ohms.

V = IR

V * 1/R = I * R * 1/R

I = V/R

I = 2/3 Amps

A pre-timed four-timing-stage signal has critical lane group flow rates for the first three timing stages of 200, 187, and 210 veh/h (saturation flow rates are 1800 veh/h/ln for all timing stages). The lost time is known to be 4 seconds for each timing stage. If the cycle length is 60 seconds,

In the given problem, it is known that the lost time for each timing stage is 4 seconds and that the cycle length is 60 seconds. The total time lost in the three timing stages is therefore\(3 × 4 = 12\)seconds.

The sum of the critical flow rates for the first three timing stages is \(200 + 187 + 210 = 597 veh/h\).The saturation flow rate for each timing stage is \(1800 veh/h/ln\).

There are 4 lanes, therefore, the saturation flow rate for 4 lanes will be \(4 x 1800 = 7200 veh/h\). Saturation flow rate - critical flow rate = unused time = \(7200 - 597 = 6603 veh/h\)

Now we must divide the unused time by 60 seconds to get the estimated effective green time.

\(6603 / 60 = 110.05 veh/s\)

Since\(110.05 veh/s\) is equivalent to \(6603 veh/min\)and the estimated effective green time is in minutes, we must divide by \(60.6603 / 60 = 110.05 veh/s\)

Therefore, the estimated effective green time of the fourth timing stage is approximately 110 seconds.

a)Mass flow rate of the refrigerant
Therefore h1= condenser inlet enthalpy =278.28KJ/Kg
saturation temperature at 1.2mpa is 46.29C
Therefore the temperature of the condenser

T2 = 46.29C - 5
