What historical event allowed both aerospace fields to make enormous strides forward?
Answer:
The world wars. Especially world War II
Explanation:
The world wars were the single most notable events that led to the leap in development of the aircraft from a simple apparatus capable of flight to a sophisticated flight machine. Airplane production was at its maximum during these periods (especially world war II) and has never seen that capacity of production again since. Countries focused on research that could add even the slightest enhancements to their aircraft in order to for it to surpass that of other countries.
1. Which of the following will cause a spark knock?
Answer:
I couldn't find options for your question online, but I can give you an explanation so you can choose the correct option.
Explanation:
A spark knock is a form of unpredictable behavior that occurs in combustion, that is, in the chemical reaction that occurs between oxygen and an oxidizable material. Such combustion is usually manifested by incandescence or flame.
The spark knock is a detonation that occurs when there is a lot of pressure in the fuel.
Some situations in which this can happen are:
Engine overloaded. Maximum pressure in the cylinders. Engine overheated. Overheated air. Long and excessive engine ignition timing. Spark plug at high temperatures.Explain the characteristics of reliable sources
Answer:

Explanation:
Answer:A reliable source is one that provides a thorough, well-reasoned theory, argument, discussion, etc. based on strong evidence. Scholarly, peer-reviewed articles or books -written by researchers for students and researchers. ... These sources may provide some of their articles online for free.
Explanation:
A generator that produces 40 kilowatts uses twice as much fuel in an hour as a generator that produces 20 kilowatts. Explain why, in terms of energy transformations.
Answer:
In terms of energy conversion/transformation the generator that produces 40 kilowatts of power will consume twice as much fuel than a generator that produces 20 watts because the more electrical power produced by an electrical generator, the more fuel is consumed. The amount of electrical energy produced is directly proportional to the fuel consumed.
Explanation:
Energy transformation is the conversion of energy from one form to another. Their are various forms of energy namely kinetic energy, electric energy, mechanical energy , chemical energy , solar energy, heat energy , nuclear energy. These energy can be transformed from one form to another . Example our body convert chemical energy through food we eat to mechanical energy.
The generator transforms mechanical energy into electrical energy . The kilowatts tells you the amount of power the generator produces .The energy is measured in kilowatts per hour which is the power used over a period of time.
In terms of energy conversion/transformation the generator that produces 40 kilowatts of power will consume twice as much fuel than a generator that produces 20 watts because the more electrical power produced by an electrical generator, the more fuel is consumed. The amount of electrical energy produced is directly proportional to the fuel consumed. So far the generator conversion efficiency are equal for both generators the generator with the higher power generation will consume more fuel per hour.
A generator that produces 40 kilowatts uses twice as much fuel as a generator that produces 20 kilowatts, due to the increased energy transformation process.
Explanation:The amount of fuel required by a generator is directly proportional to the power it produces. In this case, the generator that produces 40 kilowatts uses twice as much fuel in an hour as the generator that produces 20 kilowatts. This can be explained in terms of energy transformations.
In a generator, mechanical energy from the fuel is converted into electrical energy. The more power the generator produces, the more mechanical energy it needs, which requires a larger amount of fuel. Therefore, the generator that produces 40 kilowatts requires twice as much fuel in an hour as the one that produces 20 kilowatts.
To put it simply, the energy transformation process in the generator with higher power demands more fuel to generate the additional electrical energy.

What made computers different from machines that came before them?
Computers are intelligent machines that can make decisions on their own after digesting various data analyses, whereas machines are the least intelligent and constantly wait for user commands.
What make computers different from machines?The capacity for processing is what distinguishes computers from other types of machinery. Any device that is capable of carrying out all these functions will be regarded as a computer.
Since their invention decades ago, computers have considerably changed and advanced. Computers were incredibly big and slow in their most basic forms many years ago.
Computers have gradually gotten quicker and smaller, allowing people to utilize them almost anywhere.
Therefore, In contrast to the computers they replaced, which were people, computing machines were termed “machines” because they were machines.

The basic concept of feedback control is that an error must exist before some corrective action can be made?
Answer:
The correct answer is True.
Explanation:
The feedback control system implies that to make a feedback, there must first be an error, otherwise there will be nothing to correct.
This system works so that there is an output that is controlled through a signal.
This signal will be feedback and it will signal an error which will be detected by a controller that will allow entry into the system.
In basic words, this system processes signals, samples them in the form of an output, and re-enters them feedback to detect the error signal.
Technician A says centering cones are used on hub centric wheels. Technician B says centering cones are
used on lug centric wheels. Who is correct?
A. Technician A
B. Technician B
C. Both Technician A and Technician B
D. Neither Technician A nor Technician B
D. Neither Technician A nor Technician B is correct
What are the hub-centric wheels?Hub-centric wheels have a center bore that is the same size as the hub on the car. This means that the wheel will fit perfectly on the hub without any play. Centering cones are not needed for hub-centric wheels.
Lug-centric wheels have a center bore that is slightly smaller than the hub on the car. This means that the wheel will not fit perfectly on the hub without some play. Centering cones are used to center the wheel on the hub and prevent vibration.
Therefore, neither Technician A nor Technician B is correct. Centering cones are not used on hub-centric wheels, and they are only used on lug-centric wheels.
