Q:I need to know what object or whatever uses light energy that then leads onto electrical energy that then leads onto kinetic energy in order to work, what equipment does that? I said a Solar powered calculator but it was wrong so i'm really confused, could anyone help?:/
while a nuclear bomb explodes, you notice various sunshine as nicely because of the fact the explosion. it fairly is electromagnetic radiation: easy, electromagnetic waves, despite you like to call it. All of chemistry is in accordance with electrons, as is all of electronics. And electromagnetic waves tend to circulate those electrons to and fro. If the sunshine is extreme sufficient, the electrons leave their atoms and bypass someplace else: it fairly is the reason UV easy motives epidermis maximum cancers, it mucks with the chemistry of your physique. An EMP has comparable effects on silicon chips etc: any circuit that may no longer stand the electromagnetic growth of the EMP acts basically like an eardrum which could no longer take care of a noisy sound: the EMP growth breaks the textile.
Q:e.g. medical equipment
Best thing to do is use a surge protector and if the equipment is costly enough use one voltage stabiliser/CVT/UPS in addition.
Q:I hateTummy, supper, baggie, materials, equipment, fix used in making food, supplies, ointment
Hopefully. I have rarely heard this word used correctly. It means in a hopeful manner. The following usage is so incorrect: Hopefully, I'll be picked as the best answer. But people continue to do it, and it makes my ears bleed.
Q:im doing a project on this job and i need to know whats it about as soon as possible,thank you
Q:i'm from the UK and i want to take my GHDs, camera and phone charger, what kind of plug do i need and where can i get one, im going sunday
Cuba’s electricity is 110 volts, 60Hz, but most hotels and resorts have 220 volts. Electrical outlets take flat plug prongs. If you’re bringing an electrical appliance, you should check the resort specs before you leave to see if you need an adaptor or converter. You will need an adapter/converter specifically for digital equipment. They're slightly different than the regular adapters for hair dryers, shavers. It's not true that you can take those with you and use them. People from everywhere travel to Cuba and use their cameras, recorders, phones, etc. Most travel, hardware, and department stores will carry these.and electronic stores for sure. See the links below for descriptions of which plugs are for which appliance. This one may be good for what you're looking for: valuemax .uk/product_detail Be sure to take rechargeable batteries as you may not be able to find those there easily or inexpensively. Have an amazing time in Cuba.
Q:How electrical transmission and distribution systems works in australia as it is a huge country. what about its transmission and distribution system works across its various provinces. if any professional or anyone know it pls let me know me. thanks. sanjoy
Q:I need definitions of ship EquipmentMain switchboard:Distribution bus bars:Ship service generators:Main Engines:Prime mover:propulsion generators:propulsion motors:
It is assumed that this enquiry is in respect of large cargo or passenger vessels, not little pleasure boats. Main switchboard. This is the electrical switch panel to which all of the supplies from the service generators are led and from which all supplies to engineroom electrical equipment, deck machinery and the ships general electrical equipment, galley, navigation equipment, lighting, ventilation etc are supplied. The main switchboard comprises distribution bus bars, switches, meters and on AC ships, now in the the majority, the equipment required to synchronise the phases of the service generators. The distribution bus bars are the principal electrical conductors to which the generator outputs can be switched and from which the circuits to the rest of the ships electrical equipment are supplied. There are usually four bus bars, three carrying electricity at 415 or 440 volts three phase and a neutral bar. The current is usually supplied with a frequency of 50 Herz or 60 Herz. Ships service generators are in modern ships alternator units which supply all electrical requirements with the exception of the ship's propulsion. They are normally powered by diesel engines or steam turbines and in some naval vessels by gas turbines. Main engines. This term is invariably used for the vessel's propulsion machinery. Prime mover. This is a general term not restricted to marine practice for any machine the converts the energy of a fuel or the heat energy of steam into kinetic energy. Propulsion generators. These can be DC generators or AC alternators which have outputs dedicated for ship's propulsion purposes. The are usually connected independently of the main switchboard via a dedicated propulsion switchboard. Propulsion motors. These are electric motors which drive the ship's propellers. They are usually inboard but many modern cruise ships have their propulsion motors within pods which are outside of the main hull.
Q:Hi I have the chance to have a small premises at a garden center I would be allowed to advertise and was thinking of having a small studio thereI already have 2 home studio lights interfit background support and 3 backdrops I would be aiming to photography babies and childrendoes any one know what health and safety regulations i have to follow, what insurances is neededI already have equipment cover including my computer public liability and public indemnitydoes all equipment like the lights and backdrop have to be secured?do i have to have a credit card payment machine? basically i want to know every thingAndrea
Disabled access. Public liability Insurance. Possibly a toilet and wash basin which should also be adapted for the disabled. Tea/coffee facilities. Certificate to say that you are allowed to carry out a business on the premises. (?) Certificate from from an electrician to say that the electricity supply is safe. Fire escape. Fire extinguishers. Certificate from the Fire brigade. Thats a start for you.
Q:I have heard that an electrical ark can kill you so I would like to know what circumstances creares this condition.
Electricity tends to want to go towards the path of least resistance to something with the opposite charge. An arc is when it goes through the air in order to do that.
Q:How can I ensure my computer is properly backed up and the back-up files are unaffected by the sun? Would putting everything on CDs and DVDs work? Which would be better; an external hard disk drive or an external optical hard drive or jusr DVDs/CDs?
NASA is _not_ predicting a once in a generation solar storm. Individual solar storms can't be predicted in advance. They are predicting that the next solar _maximum_ will be _less_ than average. Our computers got through the last solar maximum without any problems. The only danger is to large electrical grids and to certain satellites in orbitnothing can happen to individual electronic devices on Earth, because our magnetic field protects us.
