When we talk about the weight of an object, we are talking about....
-
How high it is.
-
How wide it is.
-
How long it is.
-
How heavy it is.
Correct Answer
A. How heavy it is.Explanation
The weight of an object refers to how heavy it is. Weight is a measure of the force exerted on an object due to gravity. It is determined by the mass of the object and the acceleration due to gravity. Height, width, and length are measurements of the size or dimensions of an object, but they do not directly determine its weight.Rate this question:

Corrosion is the wearing away of metals due to a chemical reaction.
Correct Answer
TrueExplanation
Corrosion is indeed the wearing away of metals due to a chemical reaction. When metals are exposed to certain substances, such as moisture or acids, they can undergo a chemical reaction that causes them to deteriorate over time. This process is commonly observed in metals like iron, which can form rust when exposed to oxygen and water. Therefore, the statement "Corrosion is the wearing away of metals due to a chemical reaction" is accurate.Rate this question:

-
He perfected a process to protect against corrosion.
-
Another word for invented.
-
When you started to manufacture the product.
-
Rights to make, use, and sell the innovation.
Correct Answer
A. Rights to make, use, and sell the innovation.Explanation
The term "patented" refers to the legal rights granted to an inventor or innovator to exclusively make, use, and sell their invention or innovation. In this context, Henry F. Phillips obtained the rights to manufacture, use, and sell the Phillips screw and screwdriver through his patent in 1936. The term "patented" does not mean perfecting a process, another word for inventing, or starting the manufacturing process.Rate this question:

If a CAD engineer asks to see the 'blueprints', he is asking to...
-
See how the image looks on a screen.
-
See the technical drawings.
-
See the new printouts from the plotter machine.
-
Check the shape of the object.
Correct Answer
A. See the technical drawings.Explanation
The term "blueprints" is commonly used to refer to the technical drawings or plans of a design or construction project. These drawings provide detailed information about the dimensions, specifications, and construction methods of the object or structure. Therefore, if a CAD engineer asks to see the "blueprints," they are likely requesting to view the technical drawings to gain a better understanding of the design and its specifications.Rate this question:

Which of the following is not a function of a vacuum gripper?
-
It shines.
-
It picks up.
-
It provides suction.
-
It sucks air.
Correct Answer
A. It shines.Explanation
The given answer "It shines" is not a function of a vacuum gripper because vacuum grippers are specifically designed to pick up objects and provide suction by creating a vacuum. The purpose of a vacuum gripper is to hold and manipulate objects using suction, not to emit light or shine.Rate this question:

Complete the missing words. The integration of large numbers of tiny _________ into a small chip was an enormous improvement over the manual assembly of circuits using electronic components.
-
Vacuum tubes
-
transistors
-
Circuits
-
Devices
Correct Answer
A. transistorsExplanation
The integration of large numbers of tiny transistors into a small chip was an enormous improvement over the manual assembly of circuits using electronic components. Transistors are semiconductor devices that amplify or switch electronic signals and are essential components in modern electronic devices. By integrating a large number of transistors onto a small chip, it became possible to create more complex and powerful electronic systems, leading to advancements in technology and miniaturization. This advancement revolutionized the electronics industry and paved the way for the development of modern computers, smartphones, and other electronic devices.Rate this question:

Another word for implementation is...
-
Integration
-
Configuration
-
Installation
-
Optimization
Correct Answer
A. InstallationExplanation
Implementation refers to the process of putting a plan or system into operation. Installation is a synonym for implementation as it involves the physical or technical process of setting up and making something operational, such as installing software or hardware. Integration refers to combining different parts or components into a whole, configuration refers to the arrangement or setup of something, and optimization refers to the process of making something as effective or efficient as possible. Therefore, installation is the most appropriate synonym for implementation.Rate this question:

AutoCAD DXF (Drawing Interchange Format, or Drawing Exchange Format) is a CAD data file format developed by Autodesk for enabling data interoperability between AutoCAD and other programs. The best antonym (or opposite noun) for 'interoperability' is.....?
-
Uninteractive
-
Cross-functionality
-
Capacity
-
Incompatibility
Correct Answer
A. IncompatibilityExplanation
The best antonym for 'interoperability' is 'incompatibility'. Interoperability refers to the ability of different systems or software to work together and exchange information seamlessly. Incompatibility, on the other hand, refers to the lack of compatibility or the inability of different systems or software to work together effectively. Therefore, incompatibility is the opposite of interoperability.Rate this question:

When you combine P-type and N-type silicon in a solar cell:
-
Electrons rush from N to P, leaving the N side empty.
-
Electrons at the N-P junction eventually form a barrier.
-
Nothing happens.
Correct Answer
A. Electrons at the N-P junction eventually form a barrier.Explanation
It may seem like all the free electrons from N-type silicon would make a mad dash for the available empty spaces in P-type silicon. In reality, the electrons near the borders of each type mix, gradually creating an effective barrier -- an electrical field.Rate this question:

A solar cell can only absorb 15 to 25 percent of the sun's energy because...?
-
Not all wavelengths of light create the right reaction in the cell.
-
There's too much resistance inside the semiconductor.
-
Both A and B.
Correct Answer
A. Not all wavelengths of light create the right reaction in the cell.Explanation
When a photon of light hits a solar cell, it can free an electron, simultaneously making a place for another electron to go. But if the photon doesn't have enough energy, nothing happens. On top of that, silicon isn't as efficient at moving electrons as a conductor.Rate this question:

When light hits a solar cell, electrical current comes from:
-
Electrons traveling from the N side to the P side along a circuit
-
Electrons traveling from the N side to the P side across the N-P junction
-
Electrons traveling from the P side to the N side along a circuit
Correct Answer
A. Electrons traveling from the N side to the P side along a circuitExplanation
When sunlight hits a solar cell, it loosen electrons, creating both free electrons and spaces for the electrons to go. Add a path from N to P, and the electrons will follow it, creating an electrical current along the path.Rate this question:
