Charging and rapidly discharging a battery generates heat and: Select one: a. sulfur. b. hydrogen. c. nitrogen. d. potassium.
Answer:
a. sulfur.
Explanation:
Accelerated self-discharge: This accelerated process occurs when it exceeds the value specified in normal self-discharge.
- Moisture of the external parts of the battery during electrolyte placement or during handling.
- During the charging process, due to gas leakage which drags sulfuric acid particles from the electrolyte to the outside of the battery.
- When the battery has internal leakage in the vessels.
- In electrolyte contamination by organic materials.
Rob creates a Course_Details table that has four columns: Course_ID, Course_Name, Semester and Credits. A course may have 0.5 credit if it is for 1 semester and 1 credit if it is for 2 semesters. Which field should Rob assign as a primary key in the table?
Rob should assign the field as the primary key in this table.
Answer:
Course_ID should be the primary key
Explanation:
In databases, the primary key of a table must be a field that identifies uniquely every record possible in that table. Most common way is to assign a number starting from 1 and incrementing every new record is added to the table.
Since primary keys cannot be duplicated, the fields Course_Name, Semester and Credits, are not good choices.
The syntax for adding a primary key is:
ALTER TABLE Course_Details ADD PRIMARY KEY (Course_ID);
Which of the following components controls the opening and closing of the valves in an engine?

During an engine's intake stage, what passages inside the cylinder head of a gasoline powered engine must the incoming air-and-fuel mixture flow through in order to enter the cylinder?
A. Intake ports
B. Valve guide
C. Exhaust manifold
D. Cylinder bore
The air-and-fuel mixture flows through the intake ports during the intake stage of an engine's operation to enter the cylinder for combustion. The correct option is A. Intake ports.
During the intake stage of an engine's operation, the air-and-fuel mixture must flow through A. intake ports to enter the cylinder. These intake ports are openings in the cylinder head that channel the mixture into the cylinder's combustion chamber when the intake valve is open. This occurs in the intake stroke of the four-stroke internal combustion engine cycle, which is part of the process where heat transfer into work takes place.
The valve guide, exhaust manifold, and cylinder bore are not involved in the intake stage for directing the air-and-fuel mixture. The valve guide helps to keep the valve in proper alignment but does not channel the mixture. The exhaust manifold collects the exhaust gases from the cylinders and directs them out of the engine after the combustion process. The cylinder bore is the opening in the cylinder block where the piston moves up and down during the engine's operation.

Enter a formula in cell b7 to calculate the average value of cells b2:b6
Final answer:
To calculate the average of cells B2:B6 in Excel, enter the formula =AVERAGE(B2:B6) in cell B7. This will give you the average value for that range without needing absolute references.
Explanation:
To calculate the average value of cells B2:B6 in Excel and place the result in cell B7, you would need to enter the following formula: =AVERAGE(B2:B6).
This formula uses the AVERAGE function, which computes the mean of the numbers in a specified range by adding them together and then dividing by the count of the numbers.
It's important to note that, unlike the provided example using dollar signs ($), which indicates an absolute reference, the formula for B7 does not include these as it's not necessary for calculating the average within a fixed range.

A ___ is a name that represents a value that does not change during the program's execution. named constant variable signature named literal key term
Answer:
A constant is a name that represents a value that does not change during the program's execution. named constant variable signature named literal key term.
Explanation:
The correct answer is constant.
Each language implements constants in different ways. For example, in C you use the clause #define at the header, along with the #include clauses. In Java you can declare a variable with the final clause.
It is good practice of programming to use constants instead of numbers in the code. If you want to modify the value of the constant before executing the program, you just change at the declaration, and not at the entire code.
So:
A constant is a name that represents a value that does not change during the program's execution. named constant variable signature named literal key term.

This type of server spools documents and puts them in a queue.
application
communication
file
print
Print is the type of server that spools documents and puts them in a queue. Whenever you are printing multiple documents, it is the standard operation of the printer to prioritize those documents that came first and add to the queue the other documents waiting for printing.
A print server is responsible for spooling and queueing documents for printing in an office-style workflow. It allows multiple users to share printers efficiently and manage print jobs within an organization, contributing to the centralized management of computer resources and reducing costs. The correct option is d. print.
The type of server that is designed to spool documents and manage them in a queue is known as a d. print server. In a typical office-style workflow, print servers play a critical role by handling print jobs submitted by various users within the organization. These jobs are queued and processed in an organized manner, allowing multiple users to send documents to a single or multiple printers without conflict.
Within an organization's resources, protection of systems like File Server, Application Server, and Network Server is essential. A print server helps to streamline the process and facilitate resource sharing, such as the shared use of printers, thereby reducing the need for multiple printers. It also aids in managing computer resources more efficiently within a networked environment.
Additionally, an Application Server can be used to provide shared access to applications, reducing the need for multiple licenses and simplifying maintenance and updates, much like how a print server centralizes printing tasks. This is a common strategy in business environments to lower costs and improve organizational efficiency.

Originally 21 acts were tentatively scheduled to perform at the arena; only 10 have been booked. What is the shortfall if the other acts do not perform, assuming an average profit margin of $175,000 for each concert?
If there are originally 21 acts being performed and out if that 10 have been booked. And we want to know about the short fall and no other acts are not being performed.
The average profit margin has been given to us of $175,000 for each concert. So we will find the shortfall by calculating it this way:
21 - 10 =11 x 175000= $1925000 shortfall
Look at the code in the example below, and then answer the question.

To activate the sizing handles on a graphic, you must first _____.
Final answer:
To activate the sizing handles on a graphic, you must first select the graphic. Once selected, sizing handles appear to enable resizing. Click and drag these handles to adjust the graphic's size while maintaining its proportions with the 'Shift' key if needed.
Explanation:
To activate the sizing handles on a graphic within a document or an application, you must first click to select the graphic. Sizing handles are small points or squares that appear around the perimeter of a graphic that allow you to resize the image. When you click on the graphic with your mouse, the sizing handles will appear, indicating that the image is active and ready for manipulation.
To properly interact with these handles, simply place your cursor over one of the corners or edges until it changes to a two-sided arrow (often a diagonal arrow for corner handles or a vertical/horizontal arrow for edge handles). Click and drag to resize the image. Keeping the 'Shift' key pressed while dragging a corner handle helps maintain the original aspect ratio of the graphic to avoid distortion.
Final answer:
To activate sizing handles on a graphic, you need to click on and select the graphic. This enables the handles that allow you to resize the image.
Explanation:
To activate the sizing handles on a graphic, you must first select the graphic.
By clicking on the graphic, you make it the active object in your document or workspace. Once selected, the sizing handles will appear, usually as small boxes or circles at the corners and sides of the graphic. These handles allow you to resize the graphic proportionally or stretch it in a particular direction. Remember to use the corner handles to maintain the aspect ratio to avoid distorting the image.
