Some dolphins and bats, for example, can hear frequencies up to 100,000 Hz. Elephants can hear sounds at 14--16 Hz, while some whales can hear infrasonic sounds as low as 7 Hz (in water).
 Question: do all animals hear the same frequencies of sound as humans do Context: Ohm's law is one of the basic equations used in the analysis of electrical circuits. It applies to both metal conductors and circuit components (resistors) specifically made for this behaviour. Both are ubiquitous in electrical engineering. Materials and components that obey Ohm's law are described as ``ohmic'' which means they produce the same value for resistance (R = V/I) regardless of the value of V or I which is applied and whether the applied voltage or current is DC (direct current) of either positive or negative polarity or AC (alternating current).
 Question: is ohm's law the same for ac and dc Context: A kerosene lamp (also known as a paraffin lamp in some countries) is a type of lighting device that uses kerosene (paraffin) as a fuel. Invented by the Polish pharmacist Ignacy Łukasiewicz in 1853, kerosene lamps have a wick or mantle as light source, protected by a glass chimney or globe; lamps may be used on a table, or hand-held lanterns may be used for portable lighting. Like oil lamps, they are useful for lighting without electricity, such as in regions without rural electrification, in electrified areas during power outages, at campsites, and on boats. There are three types of kerosene lamp: flat-wick, central-draught (tubular round wick), and mantle lamp. Kerosene lanterns meant for portable use have a flat wick and are made in dead-flame, hot-blast, and cold-blast variants.
 Question: is paraffin lamp oil the same as kerosene Context: A tennis match is composed of points, games, and sets. A set consists of a number of games (a minimum of six), which in turn each consist of points. A set is won by the first side to win 6 games, with a margin of at least 2 games over the other side (e.g. 6--3 or 7--5). There is usually a tie-break if the set is tied at six games per player. A match is won when a player or a doubles team wins the majority of prescribed sets. Matches employ either a best-of-three or best-of-five set format. The best-of-five set format is typically only played in the men's singles or doubles matches at Grand Slam and Davis Cup matches.
