How fast do planes fly in mph? The typical cruising airspeed for a long-distance commercial passenger aircraft is approximately 880–926 km/h (475–500 kn; 547–575 mph). Was the mosquito faster than the Spitfire? During its trials on 16 January 1941, W4050 outpaced a Spitfire at 6,000 ft (1,800 m). The original estimates were that as the […]

What is the greatest contribution of the Bernoulli brothers to mathematics?
What is the greatest contribution of the Bernoulli brothers to mathematics? Jacob Bernoulli’s first important contributions were a pamphlet on the parallels of logic and algebra published in 1685, work on probability in 1685 and geometry in 1687. His geometry result gave a construction to divide any triangle into four equal parts with two perpendicular […]
Why was England most successful in colonizing America?
Why was England most successful in colonizing America? The English that settled the middle colonies of New York and Pennsylvania found good farmland that was great for growing food that could be sold in Europe. Finally, the English that colonized the southern colonies found that area was good for growing cash crops like tobacco. What […]
Which installation is not covered by the NEC?
Which installation is not covered by the NEC? The NEC does not cover electrical installations in ships, water- craft, railway rolling stock, aircraft, or automotive vehicles. What is the purpose of the NEC? The NEC (the National Fire Protection Association’s NFPA 70) is a widely-adopted model code for the installation of electrical components and systems. […]
Why do we use resistors?
Why do we use resistors? A resistor is a passive two-terminal electrical component that implements electrical resistance as a circuit element. In electronic circuits, resistors are used to reduce current flow, adjust signal levels, to divide voltages, bias active elements, and terminate transmission lines, among other uses. What causes resistors to burn? Blowing Up a […]
Why is a database a tertiary source?
Why is a database a tertiary source? Indexes, bibliographies, concordances, and databases may not provide much textual information, but as aggregates of primary and secondary sources, they are often considered tertiary sources. However, they may also provide access to the full text or content of primary and secondary sources. What are some examples of tertiary […]
What are 3 examples of invasive species?
What are 3 examples of invasive species? Notable examples of invasive plant species include the kudzu vine, Andean pampas grass, English ivy, Japanese knotweed, and yellow starthistle. Animal examples include the New Zealand mud snail, feral pig, European rabbit, grey squirrel, domestic cat, carp, and ferret. What are two human activities that could contribute to […]
What is the resistance seen across terminals A and B?
What is the resistance seen across terminals A and B? 5 ohms What is the formula to find equivalent resistance? The equivalent resistance of a 4-Ω and 12-Ω resistor placed in parallel can be determined using the usual formula for equivalent resistance of parallel branches: 1 / Req = 1 / R1 + 1 / […]
What can exposure to high noise levels cause?
What can exposure to high noise levels cause? Exposure to high levels of noise can cause permanent hearing loss. Neither surgery nor a hearing aid can help correct this type of hearing loss. Short term exposure to loud noise can also cause a temporary change in hearing (your ears may feel stuffed up) or a […]
