Which of the following statements is correct?

The thermostat controls the operation of the fan motor.
The 1-C contacts control the operation of the fan motor.
The L, M, and H terminals control the speed of the compressor.
Terminals 1 and L1 on the selector switch are electrically the same.

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”.

Explanation:

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]

The maximum rolling resistance = 275 lb/ton

18.14% of the bags contains less than 22 kg

Z score is used to determine by how many standard deviations the raw score is above or below the mean. It is given by:

z = (raw score - mean) / standard deviation

Given that:

Mean = 22.73 kg, standard deviation = 0.80 kg

a) For <22:

z = (22 - 22.73)/0.8 = -0.91

P(z < -0.91) = 0.1814

Answer:

  (a) 16.27 Vpk

  (b) 48.7%

Explanation:

The transformer is assumed to be an ideal 10:1 voltage divider with no internal impedance. The diode is assumed to be modeled in the forward direction by a perfect 0.7 V voltage drop with no internal impedance. That means the frequency of the supply voltage is irrelevant.

__

The peak voltage will be 0.7 V less than the transformer secondary peak voltage:

  ((120 V)√2)/10 -0.7 V ≈ 16.27 V

__

The fraction of the amplitude for which the diode is non-conducting is ...

  0.7/(12√2) ≈ 0.041248

The period of conduction is symmetrical about the peak of the waveform, so it is convenient to use the arccos function to find the (half) conduction angle:

  arccos(0.041248) ≈ 87.64°

As a fraction of half the cycle, this is ...

  conduction fraction ≈ 87.64°/180° ≈ 48.7%

The logic in attachment 2 shows an implementation using And and Or gates. The effective equation is ...

  chicken = (m·d) + (m+d)·(a+b)

The logic in attachment 3 shows an implementation using an 8-input selector. The dots at the inputs represent inversion, so those inputs to the selector represent a logic 1 (chicken).

The profit that will be made for the first and second years will be $100,000 and $460,000.

The profit of the graphics company for the first year will be:

= 4(100000) - [200000 + 100000]

= 400000 - 300000

= 100000

The profit for the second year will be:

= 4(220000) - (200000 + 220000)

Video compression is the process of encoding a video file in such a way that it consumes less space than the original file and is easier to transmit over the network/Internet.

Video compression is the process of encoding a video file in such a way that it consumes less space than the original file and is easier to transmit over the network or Internet.

A data structure known as a "Data Frame" arranges data into a 2-dimensional table of rows and columns, much like a spreadsheet. Because they provide a flexible and user-friendly method of storing and interacting with data, a Data Frame is one of the most popular data structures used in contemporary data analytics.

The name and data type of each column is specified in a schema that is part of every Data Frame. Both common data types like StringType and IntegerType as well as Spark-specific data types like StructType can be found in Spark DataFrames. The Data Frame stores missing or incomplete values as null values.

I am sorry. I don't understand too :/ I haven't learn engineering before- But if I'm not wrong, if something is black, probably it's burnt? Because you have to dip it in the water to cool down.

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

On wet roads, the chance of hydroplaning increases with the increase of speed. Thus, the given statement is true.

During rainy weather, roads may become slippery and difficult to drive on. Slippery roads may also arise as a result of snow or ice. The fact that the road surface has less traction than normal is what makes it slippery. On slippery roads, it is recommended that drivers slow down to reduce the risk of skidding, sliding, or losing control of their cars, especially when taking turns.

Drivers should also increase their following distance and avoid abrupt braking or accelerating. Drivers should not drive faster than 25 mph on slippery roads, and they should not increase their speed to avoid hydroplaning. Instead, drivers should slow down.
