input: Mains electricity

Following voltage harmonisation, electricity supplies within the European Union are now nominally 230 V 10% at 50 Hz. For a transition period (1995--2008), countries that had previously used 220 V changed to a narrower asymmetric tolerance range of 230 V +6%/10% and those (like the UK) that had previously used 240 V changed to 230 V +10%/6%. No change in voltage is required by either system as both 220 V and 240 V fall within the lower 230 V tolerance bands (230 V 10%). Some areas of the UK still have 250 volts for legacy reasons, but these also fall within the 10% tolerance band of 230 volts. In practice, this allows countries to continue to supply the same voltage (220 or 240 V), at least until existing supply transformers are replaced. Equipment (with the exception of filament bulbs) used in these countries is designed to accept any voltage within the specified range. In the United States and Canada, national standards specify that the nominal voltage at the source should be 120 V and allow a range of 114 V to 126 V (RMS) (5% to +5%). Historically 110 V, 115 V and 117 V have been used at different times and places in North America. Mains power is sometimes spoken of as 110 V; however, 120 V is the nominal voltage.

Question: The escape network was not literally underground nor a railroad. It was figuratively ''underground'' in the sense of being an underground resistance. It was known as a ''railroad'' by way of the use of rail terminology in the code. The Underground Railroad consisted of meeting points, secret routes, transportation, and safe houses, and personal assistance provided by abolitionist sympathizers. Participants generally organized in small, independent groups; this helped to maintain secrecy because individuals knew some connecting ''stations'' along the route but knew few details of their immediate area. Escaped slaves would move north along the route from one way station to the next. ''Conductors'' on the railroad came from various backgrounds and included free-born blacks, white abolitionists, former slaves (either escaped or manumitted), and Native Americans. Church clergy and congregations often played a role, especially the Religious Society of Friends (Quakers), Congregationalists, Wesleyans, and Reformed Presbyterians, as well as certain sects of mainstream denominations such as branches of the Methodist church and American Baptists. Without the presence and support of free black residents, there would have been almost no chance for fugitive slaves to pass into freedom unmolested. was there a railroad in the underground railroad

IN: A primary school (or elementary school in American English and often in Canadian English) is a school in which children receive primary or elementary education from the age of about seven to twelve, coming after preschool , infant school and before secondary school. (In some countries there is an intermediate stage of middle school between primary and secondary education.)

Text: In Ontario, the Highway Traffic Act does not prohibit ''flashing head beams''. Some have brought tickets to court, claiming the law only regulates the use of alternating lights in an attempt to impersonate emergency and law enforcement vehicles, and not a driver's manually flashing his car's headlamps to communicate with other drivers. The section that deals with alternating headlights in Ontario is Section 169 of the Highway Traffic Act. It is an offence to improperly use high-beams at night, which is dealt with by way of section 168 of the Highway Traffic Act.

Question: is it illegal to flash your headlights to warn of police ontario?
