What are 2 features that all forms of matter have? All matter has physical and chemical properties. Physical properties are characteristics that scientists can measure without changing the composition of the sample under study, such as mass, color, and volume (the amount of space occupied by a sample). What is a special property? : a […]
What is the three phases of water?
What is the three phases of water? There are three phases of water that are studied in elementary school: solid, liquid, and gas. What are the 3 state of water? One of the most basic things we are taught in school science classes is that water can exist in three different states, either as solid […]
Who has the right away at a green light?
What is another name for a decomposition reaction?
What is another name for a decomposition reaction? Decomposition reactions are also known as analysis reactions or chemical breakdowns. The opposite of this type of reaction is a synthesis, in which simpler reactants combine to form a more complex product. How can a displacement reaction be recognized? Recognizing a Single-Displacement Reaction Usually, when two compounds […]
How is communication possible without a physical medium?
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 […]
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 […]
