Explanation of POP . It\'s the question u asked DEVIL JIN |
|
Answer» (1) POP is short for Post Office Protocol, a protocol used to retrieve e-mail from a mail server. Most e-mail applications (sometimes called an e-mail client) use the POP protocol, although some can use the newer IMAP (Internet Message Access Protocol).There are two versions of POP. The first, called POP2, became a standard in the mid-80\'s and requires SMTP to send messages. The newer version, POP3, can be used with or without SMTP.(2) Pop is short for point of presence, an access point to the Internet. ISPs have typically multiple POPs. A point of presence is a physical location, either part of the facilities of a telecommunications provider that the ISP rents or a separate location from the telecommunications provider, that houses servers, routers, ATM switches and digital/analog call aggregators.(3) Pop is short for Programmed Operator (POP), a pseudo-opcode in a virtual machine language executed by an interpretive program. The Programmed Operator instructions provide the ability to define an instruction set for efficient encoding by calling subprograms into primary memory.(4) POP is short for picture-outside-picture POP is a feature found on some televisions that allows the user to divide the screen into two same-size pictures, enabling you to view a second program. Compare with picture-in-picture (PIP) It\'s plaster of paris formed by the gypsum (caso4.2h2o)i.e.formed when gypsum is heated at 373k...on heating gypsum loses water moleclue n formes pop (caso4.1/2h20)...its a white powder on again moxing with water its gives a hard solid....i.e.mainly used as plaster by doctors to cure the broken bone.... I explained it as i don\'t know ur question .if u have any question then ask it POP stands for plaster of paris. It\'s chemical formula is CaSO4.1/2 H2O.It is prepared by heating GYPSUM ( CaSO4.2H2O) at 373K or 100° C. The equation for it is as follows....... CaSO4.2H2O------->CaSO4.1/2H2O+3/2H2O. It\'s uses are as follows.................................... • it is used for plastering the fractured bones • it is used for making the caste of statues .. • it is used for making black board chalks and toys ....... ........... ........... .............. It\'s physical and chemical properties are as.. • it is a white coloured powder.• when it is heated above 100° C then it loses its water molecules and becomes anhydrous CaSO4.. • when water is added to it then it is converted into a hard mass that is GYPSUM. CaSO4.1/2H2O+3/2H2O-->CaSO2.2H2O. |

What are amphoteric oxide ? |
|
Answer» Ok , I am really so sorry.☺☺. The reaction with zinc oxide is as follows.......................... ZnO+2HCl--->ZnCl2+H2O.( Basic nature) ..... ZnO + 2NaOH--->2NaZnO2+2H2O.(Acidic nature). You didn\'t show reaction with zincoxide These are the oxides which shows both acidic and basic nature by reacting with both acids and bases . For ex - zinc oxide.... Zn+2 HCl--------> ZnCl2+H2O ( basic nature)... Zn+2 NaOH --->2NaZnO2+H2O ( acidic nature). |

How is food transported in plant |
|
Answer» Food is transport in plant from the varios part 1.Xylem and Phloem. these are xylem is transport the food from the water and solutes from the roots to the leaves and phloem is transported is leaves to the plant. transpiration in this process which water exits from the vapour,this process is transpoted to the food. Plants have two different types of \'transport\' tissue. Xylem transports water and solutes from the roots to the leaves, phloem transports food from the leaves to the rest of the plant. Transpiration is the process by which water evaporates from the leaves, which results in more water being drawn up from the roots. |

How we can say that light have dual nature . Explain it plz?? |
|
Answer» Thanks yogita ingle This wave-particle duality is most clearly seen in “double-slit” experiments, in which either electrons or photons are fired, one at a time, through a pair of holes in a barrier, and detected on a screen on the other side.Light behaves as particle as well as wave. The photoelectric effect of light is a proof of particle nature of light. The interference pattern obtained in double slit experiment is an example of wave nature of light. Wave-Particle Duality is the possession of both wave-like and particle-like properties by subatomic objects. The fundamental principle of quantum theory is that an entity that we are used to thinking of as a particle (such as an electron) can behave like a wave, while entities that we are used to thinking of as waves, such as light waves, can also be described in terms of particles (in this case, photons). |
