Answer:

Wireless

Explanation:

A wireless remote control can be an advantage to an operator who is welding close to the power source. Hence, option A is correct.

An electrical device used to wirelessly and remotely operate another device is a remote control, often known as a remote or clicker. Consumer gadgets, such as television sets, DVD players, and other home appliances, can be controlled by a remote control.

In the current electronic market, remote control systems fall into three primary categories: IR-based systems, RD-based systems, and BT-based systems. the receiver and the remote must be lined up exactly for infrared, also known as IR.

IR, on the other hand, is unable to pass through a number of materials but can operate over a much wider spectrum. This allows the user far greater freedom and control in environments with challenging terrain and obstacles.

Thus, option A is correct.

The only solution of the equaiton 2x² + 8x = x² - 16 is -4.

Step by step solution of the given equation is as follows:

The equation is 2x² + 8x = x² - 16

Rewriting the equation

          2x²  - x² + 8x + 16 = o

This gives  

         x² + 8x + 16 = o

Now this quadratic equation can be written as

         x²+ 4x + 4x + 16 = o

         x (x + 4) + 4 (x + 4) = o

         (x + 4) (x + 4) = o

         x + 4 = o    &      x + 4 = o

Answer:

  48.00 microamps

Explanation:

The base voltage is limited by the zener to 5.5 V. If we assume the B-E voltage drop is 0.7 V, then the voltage across RE is 5.5-0.7 = 4.8 volts. That means the emitter current is 4.8/2.0k = 2.4 mA.

The base current is that amount divided by (1+β), so is 2.4 mA/(1+49) = 48 μA.

Explanation:

In this code, a method "calculate_storage" is declared that holds a value "filesize" in its parameters, inside the method "block_size" is declared that holds an integer value, and defines "full_blocks and partial_block_remainder" variable that holds the quotient and remainder value and use it to check its value and return its calculated value. Outside the method, three print method is declared that calls the method and prints its return value.

The expression for the current is i(t) = -10000 exp(-100t) A.

i(t) = C * dv/dt
In this case, we have a capacitor with a capacitance of 1 HF, and the voltage across it is given by:
v(t) = 100 exp(-100t) V
To find the rate of change of voltage with respect to time, we take the derivative of v(t):
dv/dt = -100 * 100 exp(-100t) V/s
i(t) = C * dv/dt
i(t) = 1 HF * (-100 * 100 exp(-100t) V/s)
i(t) = -10000 exp(-100t) A
i(t) = -10000 exp(-100t)

Given the voltage function: v(t) = 100 exp(-100t) V, let's find its derivative:
dv(t)/dt = -10000 exp(-100t)
i(t) = 1 * (-10000 exp(-100t))

The air velocity is 48.1 meters per second.

A pitot-static probe, connected to a water manometer, measures air velocity by comparing the dynamic pressure and static pressure. In this scenario, the fluid levels difference in the two arms is 7.3 cm.

To determine air velocity, we first need to convert the pressure difference from cm of water to Pa (Pascal). 1 cm of water is approximately equal to 98.1 Pa, so the pressure difference is 7.3 cm * 98.1 Pa/cm = 716.33 Pa.

Next, we can use Bernoulli's equation to find the air velocity (v):

Dynamic pressure = (1/2) * density of air * v².

Rearrange the equation and plug in the values:

v = √((2 * 716.33 Pa) / (1.25 kg/m³)).

Solving for v, we get approximately 48.1 m/s.

Answer:

V = 36.4 m³ = 4.86 gallons

W = 80193.88 lbf = 356720 N = 356.72 KN

Explanation:

We have the following data given in the question:

At = Total area of roof =  1967 ft²

h = Annual Rainfall = 14 inches = 1.17 ft

V = Volume of tank in m³  and gallons = ?

W = Weight of water in N and lbf = ?

So, for volume we know that the area of roof that receives rainfall is 56% of total area and 14 inches of annual rainfall means  that there is a standing height of 14 inches of rain water for a given area, for 1 year.

Area to receive rain = A = 0.56*1967 ft² = 1101.52 ft²

Now,

Volume = V = A * h = 1101.52 ft²)(1.17 ft)

V = 1285.11 ft³

Converting to m³:

V = (1285.11 ft³)(1 m³/35.3147 ft³)

V = 36.4 m³

Converting to gallons:

V = (1285.11 ft³)(1 m³/264.172 gal)

V = 4.86 gal

Now, for the weight of water, we use formula:

W = ρVg

where,

W = weight of water = ?

ρ = Density of water = 1000 kg/m³

V = Volume of tank = 36.4 m³

g = 9.8 m/s²

Therefore,

W = (1000 kg/m³)(36.4 m³)(9.8 m/s²)

W = 356720 N = 356.72 KN

Converting to lbf:

W = (356720 N)(1 lbf/4.44822 N)

W = 80193.88 lbf

This question is incomplete, the complete question is;

An air-standard Diesel cycle engine operates as follows: The temperatures at the beginning and end of the compression stroke are 30 °C and 700 °C, respectively. The net work per cycle is 590.1 kJ/kg, and the heat transfer input per cycle is 925 kJ/kg. Determine the a) compression ratio, b) maximum temperature of the cycle, and c) the cutoff ratio, v3/v2.

Use the cold air standard assumptions.

Answer:

a) The compression ratio is 18.48

b) The maximum temperature of the cycle is 1893.4 K

c) The cutoff ratio, v₃/v₂ is 1.946

Explanation:

Given the data in the question;

Temperature at the start of a compression T₁ = 30°C = (30 + 273) = 303 K

Temperature at the end of a compression T₂ = 700°C = (700 + 273) = 973 K

Net work per cycle \(W_{net\) = 590.1 kJ/kg

Heat transfer input per cycle Qs = 925 kJ/kg

a) compression ratio;

As illustrated in the diagram below, 1 - 2 is adiabatic compression;

so,

Tγ\(^{Y-1\) = constant { For Air, γ = 1.4 }

hence;

⇒ V₁ / V₂ = \((\) T₂ / T₁ \()^{\frac{1}{Y-1}\)

so we substitute

⇒ V₁ / V₂ = \((\)  973 K / 303 K  \()^{\frac{1}{1.4-1}\)

= \((\)  3.21122  \()^{\frac{1}{0.4}\)

= 18.4788 ≈ 18.48

Therefore, The compression ratio is 18.48

b) maximum temperature of the cycle

We know that for Air, Cp = 1.005 kJ/kgK

Now,

Heat transfer input per cycle Qs = Cp( T₃ - T₂ )

we substitute

925 = 1.005( T₃ - 700 )

( T₃ - 700 ) = 925 / 1.005

( T₃ - 700 ) = 920.398

T₃ = 920.398 + 700

T₃ = 1620.398 °C

T₃ = ( 1620.398 + 273 ) K

T₃ = 1893.396 K ≈ 1893.4 K

Therefore, The maximum temperature of the cycle is 1893.4 K

c)  the cutoff ratio, v₃/v₂;

Since pressure is constant, V ∝ T

So,

cutoff ratio S = v₃ / v₂  = T₃ / T₂

we substitute

cutoff ratio S = 1893.396 K / 973 K

cutoff ratio S = 1.9459 ≈ 1.946

Therefore, the cutoff ratio, v₃/v₂ is 1.946

To solve trusses like this, you need to use the method of joints. This means that you calculate the forces at each joint in the truss and then use the equations of equilibrium to solve for the unknown forces.

Equilibrium is a state of balance or a steady state in which opposing forces or influences are balanced. In economics, it is a situation in which all economic forces are balanced and in the absence of external influences the values of economic variables will not change. Equilibrium is the result of market forces of supply and demand being equal; where the quantity of a good or service that suppliers are willing to provide is equal to the quantity that consumers are willing and able to purchase. It is a state of no change where all economic variables such as price and quantity remain constant.

Answer:

i) Heat rejection =  1.0288 KJ

  Network production = 1.212 kJ

ii) Thermal efficiency = 54.08%

   mean effective pressure = 353.5 kPa

Explanation:

Given data :

Compression ratio ( r )  = 7

P1 ( initial pressure ) = 90 kPa,

T1 ( initial temperature ) = 27°C + 273 = 300 K

V1 = 0.004 m^3

Max cycle Temperature = 1127°C for each repetition of the cycle

i) Determine the heat rejection and net work production

considering that process 1-2 is an Isentropic compression

Find ; T2 = T1 ( r )^1.4-1

      T2 = 300 ( 7 )^0.4  = 653.371 K

    P2 = P1( r )^k

          = 90 ( 7 )^1.4  = 1372.081 kPa

considering that process 3-4 is an Isentropic expansion

T4 = T3 / r^k-1

    = 1400 / 7^(1.4 -1 ) = 642.82 K

Next ; Calculate the value of m

m = P1V1 / RT1   = 90(0.004) / 0.287 ( 300 )

                      m = 4.18 * 10^-3 kg

Finally :

amount of heat rejected = mCv ( T4 - T1 )

                                          = 4.18 * 10^-3 ( 0.718 ) ( 642.82 - 300 )

                                    Qout  = 1.0288 KJ

amount of heat added ( Qin ) =  mCv ( T3 - T2 )

                                                = 4.18 * 10^-3 ( 0.718 ) ( 1400 - 653.371 )

                   hence           Qin  = 2.2408 kJ

Network production( Wnet) = Qin - Qout

                                  = 2.2408 - 1.0288 ) KJ

                                  = 1.212 kJ

ii) Determine the thermal efficiency and mean effective pressure of the cycle

Thermal efficiency = 1 - Qout / Qin

                               = 1 - ( 1.0288 / 2.2408 )  = 54.08%

mean effective pressure = Wnet / V1 ( 1 - 1/r )

                                         = 1.212 / 0.004 ( 1 - 1/7 )

                                         = 353.5 kPa
