What are two ways you can see that there is a smaller load going to the base of the transistor?
Answer:
Transistor switches can be used to switch a low voltage DC device (e.g. LED’s) ON or OFF by using a transistor in its saturated or cut-off state. Cut-off RegionHere 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”.

Mr. and Ms. Boren have two children, John and Jane. When eating out they will go to a restaurant that serves only hamburgers or one that serves only chicken. Before going out, the family votes to decide on the restaurant. The majority wins, except when Mom and Dad agree, and in that case, they win. Any other tie votes produce a trip to the chicken restaurant.
Required:
Design a logic circuit that will automatically select the restaurant when everyone votes.
Explanation:
The logic is captured in the Karnaugh map of the first attachment. M and D refer to Mom and Dad, respectively, and A and B refer to the children. A logic 1 is a vote for Chicken, 0 is a vote for Hamburger.
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).
A specialist graphics company is investing in a new machine which enables it to make high-quality prints for its clients. Demand for these prints is forecast to be around 100,000 units in first year and 220,000 units in second year. The fixed cost of purchasing a machine is €200.000 and
maximum printing capacity of a machine 100.000 unit per year. The variable cost of printing is
€1 per unit. The company believes they will be able to charge €4 per unit for producing the prints.
What profit are they likely to make in the first and second years?
The profit that will be made for the first and second years will be $100,000 and $460,000.
How to calculate the profit?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)
= 880000 - 420000
= 460000

Having a bluish or black color of the material means it is ___________ so dip it in the water to cool down
Explanation:
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".

Explanation:
G A wheel-tractor scraper is operating on a level grade. Assume no power derating is required for equipment condition, altitude, temperature, and so on. Disregarding traction limitations, what is the maximum value of rolling resistance (in pounds per ton) over which a loaded scraper can maintain a speed of 11 mph
The maximum value of rolling resistance over which a loaded scraper can maintain in a speed of 11 mph is 275 lb/ton
What is a maximum rolling resistance?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;
For 11 mph speed, the required total resistance is ≅ 25%Grade resistance = 0%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

A half-wave rectifier circuit with a 1 kΩ load operates from a 120 V (rms value), 60 Hz household supply through a 10-to-1 step-down transformer. (For sine wave, V rms= V pk/√2 .) Assume the diode voltage is 0.7 V at forward bias. (a) What is the peak voltage of the rectified output? (b) For What fraction of the cycle does the diode conduct (calculate the percentage)?
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.
__
(a)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
__
(b)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%

What is a data frame?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.

4. On wet roads, the chance of hydroplaning increases with the increase of speed.
True
False
Answer:
The answer to the question is True
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.
