How is communication possible without a physical medium? An unguided transmission transmits the electromagnetic waves without using any physical medium. Therefore it is also known as wireless transmission. In unguided media, air is the media through which the electromagnetic energy can flow easily. What is the role of transmission medium in a network? Transmission media […]
What are the four parts of a medical term?
What are the four parts of a medical term? There are a total of four different word parts, and any given medical term may contain one, some, or all of these parts. We will classify these word parts as: (1) roots, (2) prefixes, (3) suffixes, and (4) linking or combining vowels. What three rules dictate […]
What is the deepest hole ever dug?

It’s well over 150 feet in length. What was found in the ocean February 22 2021? February 22, 2021: Glass Sponge These sponges, […]
What direction do surface winds move in the Northern Hemisphere?
What direction do surface winds move in the Northern Hemisphere? The Coriolis effect makes wind systems twist counter-clockwise in the Northern Hemisphere and clockwise in the Southern Hemisphere. The Coriolis effect causes some winds to travel along the edges of the high-pressure and low-pressure systems. Why is Coriolis effect different in Southern Hemisphere? The reverse […]
Is Split Brain bad?
Is Split Brain bad? Disadvantages of Having a Split Brain When the right and left side of the brain are un able to communicate then it can cause an almost split personality and actions performed by either hemisphere can be performed without the other hemisphere being aware of it. What do split brain patients teach […]
What does V mean in physics?
What is a good U-value?
What is a good U-value? The best insulating materials have a U-value of close to zero – the lower the better. Building regulations currently stipulate that for a new building, the elements must have maximum U-values as follows: Wall – 0.3 W/m2k. Roof – 0.15 W/m2k. What is a good window U-value? In a cold […]
What is the basic principle of scintillation detectors?
What is the basic principle of scintillation detectors? a. The basic principle of pulse height spectroscopy is that the light output of a scintillator is proportional to the energy deposited in the scintillation material. The standard way to detect scintillation light is to couple a scintillator to a photomultiplier. What is scintillation efficiency? Scintillation efficiency […]
What is carbon 14 used to date?
What is carbon 14 used to date? Radiocarbon dating (also referred to as carbon dating or carbon-14 dating) is a method for determining the age of an object containing organic material by using the properties of radiocarbon, a radioactive isotope of carbon. What is the lifespan of carbon 14? Carbon-14 has a half-life of 5,730 […]
What method did scientists use to determine the age of Earth quizlet?
What method did scientists use to determine the age of Earth quizlet? Radio metric dating is a method used to show the age of rocks by measuring the amounts of radioactive substance found in rocks. Which unit of geologic time is the oldest? The primary and largest catalogued divisions of time are periods called eons. […]
