Answer:
Example problem
Explanation:
(a) The source rate can be calculated as the product of the picture sample size and number of pixel per sample size.
Given:
Picture sample size = 480 * 500. The number of pictures sent per second = 30.
Hence sample size = 480 * 500 * 30 = 7.2e6.
Since each pixel (sample) can take one of 32 values (voltage levels), hence it needs

A team of programmers is trying to determine the efficiency of a piece of code. They run the code with inputs of different sizes and also record the number of iterations through the core block of code. The data is recorded in the table below. Input Size Iterations 200 400 600 10 20 30 40 50 100 800 1000 2000 Based on the data provided, does this algorithm run in a reasonable or unreasonable time? Explain your answer Unreasonable because this is exponential.
Based on the growth rate of iterations as input is increased, fair and unreasonable algorithms are distinguished.
What is efficiency of code?A general word used to describe the dependability, speed, and programming approach utilized in developing codes for an application is "code efficiency." Algorithmic effectiveness and the speed at which software is executed at runtime are directly related to code efficiency.
Because the algorithm does not grow exponentially, we can assume that it runs in a reasonable length of time.
assessing the mathematical function that simulates the algorithm's growth rate as the number of inputs increases;
200 equals 10,000; k is the proportionality constant.
k = 200/10\sk = 20
As a result, n = 20i, where I is the input size, is the function that represents the number of iterations.
Because the iteration does not increase exponentially, it completes in a reasonable amount of time.

Any collection of data or information that has been properly structured for quick search and retrieval by a computer is referred to as a database, often known as an electronic database.
What is electronic database?Databases are designed to make it easy to save, retrieve, edit, and delete data while carrying out various data-processing tasks. In response to queries, a database management system (DBMS) retrieves data from the database.Databases are briefly discussed after that. See computer science: Information systems and databases; information processing for a comprehensive explanation.A file or collection of files used to store a database. These files' contents can be divided up into records, each of which has one or more fields. The fundamental units of data storage are fields, and each field typically contains data related to one feature or attribute of the thing that the database is describing. Additionally, records are arranged into tables that contain details on the connections between their various fields. A database in the strict sense offers cross-referencing capabilities, despite the fact that the term "database" is used broadly to refer to any collection of information in computer files. Users can quickly search, rearrange, organize, and choose the fields in numerous records to access or produce reports on certain data aggregates using keywords and a variety of sorting instructions.

The pn junction is said to be in reverse biased condition when the positive terminal of a voltage source is linked to the n-type area and the negative terminal of the source is connected to the p-type region. A p-n-junction has a high resistance when it is reverse biased and a significant current flow when it is forward biased. Similar to a vacuum diode, the unidirectional property. As a result, p-n junction is also known as junction diode. Current can flow more freely in one direction than another via a diode (PN junction) in an electrical circuit.

To increase the steel's hardenability in order to make it stronger. The quantity of boron needed to make a difference can be as little as 3 ppm, depending on the kind of steel and carbon content.
Steels are, in theory, binary systems made up of the host element iron and the alloying element carbon, with a maximum concentration of 2% carbon (any iron-carbon alloy with more than 2% carbon is known as cast iron!). Iron alone would be too soft to be used as a building material, thus the carbon gives the essential strength and hardness. A greater knowledge of the iron/carbon alloy system is necessary to be able to develop steels that meet these various needs (high hardness or high strength, or a compromise of both). Compared to a non-alloy steel, adding boron may dramatically enhance the hardness. The maximal hardness can be much greater than 380 HV for typical cooling speeds t8/5 up to around 10 s, and the microstructure's toughness can be decreased.

A wedge and a screw are similar because they both _____.
It increases force and modifies its direction at the same time, a moving inclined plane is a wedge, and a screw is a cylinder that has an inclined plane wrapped around it.
What are a wedge and a screw?A screw is a straightforward device connected to the inclined plane, much like a wedge.
Imagine an inclined plane wrapped around a cylinder to represent a screw, a cylinder that has an inclined plane.
The screw's threads are formed by this spirally inclining plane, an input force is applied to a screw when it is twisted into a piece of wood.
Therefore, a moving inclined plane is a wedge, and a screw is a cylinder that has an inclined plane wrapped around it.

technician a says that a micrometer should be checked for calibration before use. technician b says the outside micrometer measures inside dimensions. who is correct?
Technician A micrometer should be checked for calibration before use.
What is micrometer?
In addition to other metrological instruments like dial, vernier, and digital callipers, a micrometer—also referred to as a micrometre screw gauge—is a tool with a calibrated screw that is frequently used for precise measurement of components throughout mechanical engineering, machining, and most mechanical trades. Typically, but not always, micrometres have the shape of callipers. The item to be measured is positioned between both the spindle and the anvil, which is a highly precisely machined screw. By moving the ratchet knob or thimble, the spindle is rotated until the anvil and the thing being measured are softly in contact.
To determine the apparent diameter either celestial planets or tiny things, micrometres are also found in telescopes and microscopes.
