Answer:

Message packet

Explanation:

The ans is message packet

The correct option is D. Packet switching​ is a method of switching in which the message is divided into small packets.

The message is broken into smaller pieces when using packet switching. Each of these discrete components of the communication, known as packets, has a unique source and destination address. Only based on these addresses is each packet sent forward through the network.

The method through which nodes control or switch data to send it between particular places on a network is known as switching. There are three typical switching methods: Switching a circuit. Switching of packets. Switching messages.

Small data packets are sent between different networks using packet switching. These data "packets" or "chunks" enable quicker, more effective data transport. When a user transfers a file over a network, it frequently travels in smaller data packets rather than all at once.

Thus, the correct option is represented by option D. In the packet switching method the message is divided into small packets.

The initial pressure in the cylinder of 10 bar of argon with [tex]C_p[/tex] = (5/2)·R

and the added gas at pressure of 50 bar gives the following values.

(a) 400.6 K

(b) 51.184 J

(c) The pressure of the cylinder when it is shipped is 37.194 bar

(a) Adiabatic compression, we have;

[tex]\dfrac{p_{1}}{p_{2}} = \mathbf{\left (\dfrac{T_{_{1}}}{T_{2}} \right )^{\dfrac{k}{k-1}}}[/tex]

Where;

[tex]k = \dfrac{C_p}{C_v} = \mathbf{\dfrac{C_p}{C_p - R}}[/tex]

Therefore;

[tex]K= \mathbf{\dfrac{\frac{5}{2} \cdot R}{\frac{5}{2} \cdot R - R} }= \dfrac{5}{3}[/tex]

Which gives;

[tex]\dfrac{10}{50} = \left (\dfrac{298}{T_{2}} \right )^{\dfrac{\frac{5}{3} }{\frac{5}{3} -1}} = \left (\dfrac{298}{T_{2}} \right )^{2.5}[/tex]

[tex]\dfrac{50}{10} = \mathbf{ \left (\dfrac{T_2}{298.15} \right )^{2.5}}[/tex]

[tex]ln(5)= 2.5\cdot ln\left (\dfrac{T_2}{298.15} \right )[/tex]

[tex]T_2 = 298 \times e^{\dfrac{ln(5)}{2.5} } \approx \mathbf{567.29\, K}[/tex]

The temperature

Using an ideal gas model, we have;

[tex]\dfrac{V_{1}}{V_{2}} = \mathbf{\dfrac{P_{2}\times T_{1}}{T_{2} \times P_1}}[/tex]

Which gives;

[tex]\dfrac{V_{1}}{V_{2}} = \dfrac{50\times 298}{567.29 \times 10} \approx 2.625[/tex]

V₁ = 2.625·V₂

Volume occupied by the gas in the cylinder after the pressure increases is therefore;

[tex]V_2 = \dfrac{V_1}{2.625} \approx 0.381 \cdot V_1[/tex]

Volume of gas added is therefore;

[tex]V =V_1 - \dfrac{V_1}{2.625} = 0.619\cdot V_1[/tex]

Considering a molar volume of gas, we have;

0.040 × 0.619 × 2.5×8.3145×(T₃ - 298) = 0.040 × 0.381 × 2.5×8.3145×(567.29 - T₃)

Solving gives;

T₃ ≈ 400.6 K

For a molar volume of gas cylinder, the temperature just after the valve is closed is T₃ ≈ 400.6 K

(b) If the cylinder sits in the storage for a long time, and heat is conducted out, we have;

The temperature of the cylinder will revert to room temperature of 298 K

The heat transferred is therefore;

0.040 × (2.5 × 8.3145 - 8.3145) ×(400.6 - 298) ≈ 51.184

The heat transferred from the cylinder is 51.184 J

(c) The pressure of the gas in the cylinder is therefore;

[tex]\dfrac{P_1}{T_1} = \mathbf{\dfrac{P_2}{T_2}}[/tex]

Which gives;

[tex]P_2= \mathbf{\dfrac{P_1}{T_1} \times T_2}[/tex]

Therefore;

[tex]P_2= \dfrac{50}{400.6} \times 298 \approx 37.194[/tex]

The pressure of the cylinder when it is shipped is 37.194 bar

Answer:

Here the operating conditions of the transistor are zero input base current ( IB ), zero output collector current ( IC ) and maximum collector voltage ( VCE ) which results in a large depletion layer and no current flowing through the device. Therefore the transistor is switched “Fully-OFF”.

2.Saturation Region

Here the transistor will be biased so that the maximum amount of base current is applied, resulting in maximum collector current resulting in the minimum collector emitter voltage drop which results in the depletion layer being as small as possible and maximum current flowing through the transistor. Therefore the transistor is switched “Fully-ON”.

For example, if a steel is burnt, it will change color like blue.

So the answer is "burnt".

Having a bluish or black color of the material means it is burnt so dip it in the water to cool down

The maximum value of rolling resistance over which a loaded scraper can maintain in a speed of 11 mph is 275 lb/ton

The maximum rolling resistance is the maximum rolling friction that can cause the motion of a body or a substance to resist the force when rolled on a flat surface.

Using Rimpull Performance Chart for wheel-tractor scraper;

The total resistance = (gross+rolling) resistance

25% = 0% - rolling resistance

rolling resistance = 25%

The maximum rolling resistance = rolling resistance percentage × speed

The maximum rolling resistance [tex]\mathbf{=25\% ( \dfrac{11 \ lb/ton}{1 \% \ resistance})}[/tex]
