A finite part of a line?

Technically, in geometry, there is no such thing. By definition, a line is infinite. A "line segment" is a finite portion of a line. In everyday speech, people might sometimes refer to a line segment as a finite line. But if you said this on a math test, you would fail the test.

Difference between steam and water vapor?

In hydro distillation, water is added with raw plant material and boiled to give steam. In steam distillation, steam is passed through a chamber that contains raw materials. In hydro distillation, an hydro machine is used to capture the stream which is further condensed. Whereas the steam is condensed by flowing into a chilled condensed chamber.

What are the differences between proportional counter and gm counters in radiation monitoring?

The proportional counter is operating in linear mode, so the energy pulse measured by the detector is proportional to the energy of the radioactive particle. Thus, the average current flow in the detector is a function of both the activity (curies) and the energy (kEv) of the source. This detector is better at measuring the dose rate of the source. The Geiger-Muller detector, on the other hand, operates in avalanche mode, so the energy pulse measured by the detector is not proportional to the energy of the radioactive particle. Thus, the average current flow in the detector is a function of only the activity (curies) of the source. This detector is better at measuring the activity of the source, and can be more sensitive to lower energy particles, at the loss of discrimination of what those particles are.

What is the grain size of fine sand?

The grain size of fine sand typically ranges from 0.075 to 0.425 millimeters in diameter.

What is Average cost and variable cost?

Average cost is the total cost of producing a given quantity of output divided by the quantity produced. Variable cost is the cost that varies with the level of output produced. It includes costs such as raw materials, labor, and utilities that are directly related to production.

Does Hounsfield unit use dental implantology?

Yes, Hounsfield units are used in dental implantology. They help in assessing bone density and quality at the implant site, which is crucial for the success of implant placement. High bone density is favorable for optimal osseointegration of the dental implant.

Advantages using computer models for testing new treatments?

Computer models allow researchers to quickly test a wide range of scenarios without the need for expensive and time-consuming clinical trials. They can help predict potential outcomes, optimize treatment regimens, and identify potential side effects before moving to human trials. Additionally, computer models can be used to simulate the effects of different variables and conditions, providing valuable insights that can inform decision-making in the drug development process.

What is a surface model?

A surface model is a digital representation of the outer geometry or shape of an object without depicting its internal structure or properties. It consists of surfaces defined by mathematical equations that approximate the form of the object, such as in computer-aided design (CAD) software for creating 3D models. Surface models are commonly used in industries like engineering, architecture, and entertainment for visualization and design purposes.

What is PPM in full?

Answer It stands for principle and practices of management, which gives detail study about the working of an organization.


Answer It could also stand for "parts per million", which is a unit for measurement of concentration.

Explain why naphthalene or moth balls disappear without wetting the clothes?

Naphthalene (moth balls) sublimes, which means it transitions from a solid to a gas without going through a liquid phase. This process occurs due to the substance's high vapor pressure at room temperature, causing it to evaporate directly into the air. As a result, naphthalene can disappear from clothes without leaving any visible residue.

Is granite heterogeneous or homogeneous mixture?

Granite is a heterogeneous mixture. This means that it is made of different substances that remain physically separate.

What is 0perating System?

An operating system is a software that manages computer hardware and software resources, providing services for computer programs to run effectively. It acts as an intermediary between applications and the hardware, controlling and coordinating various functions such as memory allocation, process management, file system management, and input/output operations. Popular examples of operating systems include Windows, macOS, Linux, and Android.

How many kilos are in a giga?

A kilobyte is 1,024 (2^10) bytes. A megabyte is 1,024 kilobytes. A gigabyte is 1,024 megabytes. So a gigabyte is 1,024 * 1,024 kilobytes = 1,048,576 kilobtes.

What is the difference between fine-grained and coarse-grained atomic actions?

A Fine-grained atomic action is one that can be implemented directly by an indivisible machine instruction. A coarse-grained atomic action is a sequence of fine-grained atomic actions that appear to be indivisible.

How do you establish reliability?

To establish reliability as related to computer programming, you must test the program.

To establish reliability in life, you must be reliable: If you say you will do something, do it. If you say you will be somewhere, be there. Always follow through with what you say.

Suppose that a stop and wait ARQ system has a time out value that is less than the time required to receive an acknowledgement Sketch the sequence of frame exchanges that transpire between two station?

suppose that a stop and wait ARQ system has a time out value that is less then the time required to receive an acknowledgement. sketch the sequence of frame exchanges that transpire between two stations when station A sends five frames to station B and no errors occur during trasmission. what is a mail server? briefly explain specifying the protocols involved, how a sender can send a mail to the server and the recipient retrieves it from the server? what is datagram

How does the behavior of option buttons differ from the behavior of check boxes?

In Check box, you can select multiple options. In Option Button (also known as Radio button), you can select only one option at a time.

A Check box is rather similar to an option button. The Value property of both the controls is tested to check the current state. Check boxes are valid as a single control whereas a single option button is probably counts- intuitive.Check boxes are not mutually exclusive.

What is 'multi-valent'?

Multivalent refers to the ability of an atom to form multiple chemical bonds with other atoms. It can also refer to a molecule or ion that can donate or accept multiple electrons in a chemical reaction. In the context of vaccines, multivalent vaccines contain antigens from multiple strains or types of a pathogen to provide protection against various strains.

What is the best way to learn as much as possible about chemistry and physics and quantum mechanics?

There is no substitute for attending university classes on the subject, also participating in research related to any of those fields is very helpful in linking the concepts with application.

As for on your own, I highly recommend studying textbooks on the subjects available for lend at any public university. Books that only contain concepts (those that are found at chain bookstores) without any math are very limited in helpfulness.

Purposes of corel draw 11?

Corel Draw 11 is a graphic design software used for creating vector graphics, such as logos, illustrations, and print materials. It provides tools for creating layouts, manipulating text, and editing images. Corel Draw 11 is commonly used for design projects in industries like advertising, marketing, and publishing.

What is mean by Cell spacing?

Cell Spacing controls the distance between the cells. To specify cell spacing and it's distance, you add the line CELLSPACING="X" to the <TABLE> tag so the final result looks like: <TABLE CELLSPACING="X"> The X in the line, is replaced with the number of pixels you want between the cells.
