Which phase of matter is the rarest in the solar system?
liquids
Four phases of SDLC?
PlanningThe Planning Phase is the first phase of the SDLC. During this phase, the group that is responsible for creating the system must first determine what the system needs to do for the organization. Often this means asking questions such as...What do we need this system for?What will the system do for the organization?How are we going to make this system?During this initial phase, resources (both human and technology resources) are put together and a project plan is devised by the project manager.AnalysisThe Analysis Phase is the second phase of the SDLC and is when the group that has been placed in charge of the project must decide if the project should go ahead with the resources available. This also includes looking at any existing system to see what it is doing for the organization and how well that system is doing it's job. The feasibility of the project is also considered, and the group has to ask questions such as...Can this system be created with the resources (and budget) we have available?Will this system significantly improve the organization?Does the old system even need to be replaced?DesignThe Design Phase is the third phase of the SDLC and it involves the actual creation and design of a system. This involves putting together the different pieces that will create the system. In a database approach, this would include...The server hosting the databaseThe software that will form the database (Access, Oracle, mySQL, etc)Other needed DBMS (DataBase Management System) softwareImplementationThe Implementation Phase is the final phase of the SDLC and it involves the actual construction and installation of a system. This phase also includes the maintenance of the system and any future updates or expansion of the system.
What happened during the accretion phase of the early solar system?
Particles grew by colliding and sticking together :) u have to love mastering astronomy
When units are finished in the available phase what phase do they go to next?
the unit returns to the reset phase
What are the moon phases in order starting with full moon?
Full Moon -> Waxing gibbous phase -> First quarter phase -> Waxing crescent phase -> New moon -> Waning crescent phase -> Last quarter phase -> Wanning gibbous phase -> Full Moon
In a modern industrial plant the most likely polyphase power system in use is a A. one-phase system. C. three-phase system. B. two-phase system. D. four-phase system.?
A "three-phase system" is a polyphase system having three phases. The term "polyphase system" just means a system having multiple phases. If it is used by itself, "a polyphase system" doesn't mean "a three-phase system".
What of an element is determined experimentally by bombardment of atoms in the vapor phase with a stream of electrons?
The answer that you wish to acquire is ionization energy. pretty sure at least. ;)
Why 3 phase ac systems is preferred to 4 phase?
3 phase system has more power than a single phase system
How many days was the battle of Vicksburg?
The final phase of the siege lasted forty days.
How does a two-phase system differ from a three phase system?
A two-phase system is archaic and you are unlikely to find it in use anywhere these days, so it is mainly of historical interest. A two-phase, three-wire system, consists of two phase voltages, displaced from each other by 90 electrical degrees, and a phase voltage which is 1.414 x phase voltage.A three-phase system consists of three phase voltages which are displaced from each other by 120 electrical degrees. In the case of a three-phase, three-wire, system, the line voltages are numerically equal to the phase voltages; in the case of a three-phase, four-wire, system, the line voltages are 1.732 x phase voltage.
What is Electricity use difference between 3 phase and 1 phase?
A two-phase a.c. system is an archaic system, in which two phase voltages are generated 90 electrical degrees apart. It has nothing whatsoever to do with the US 'split phase' system that supplies North American homes. A two-phase system can be a four-wire system, or a three-wire system, and was useful because, unlike a single-phase system, it could create naturally rotating magnetic fields in induction motors. It has long been superseded by the three-phase system.
Can single phase 200v from japan use in US with two phase 120v 240V?
The US system is not a two-phase system; it's a split-phase system. But, to answer your question, probably not without damaging the Japanese device.
What is kando system?
it convert the single phase in to three phase.
What cannot be considered a single phase?
Any load that needs three legs from a three phase system can not be considered single phase. Single phase from a three phase system only needs a connection to two legs.
How many volts is there in a single phase?
The number of Volts in a residential service drop in the US is either 120V 2 Wire, 120V-208V Network, or 120-240V 3 Wire. A 120-208V Network service is not single phase, but its 120V portion is.
Why 3 phase and single phase?
3 Phase system is for industrial use and 1 phase is for house hold application
How do you convert a 3-phase system to a single phase?
By having a transformer with 3 phase input and single phase out put
