QUES: Operating at normal power line frequencies, universal motors are often found in a range less than 1000 watts. Universal motors also formed the basis of the traditional railway traction motor in electric railways. In this application, the use of AC to power a motor originally designed to run on DC would lead to efficiency losses due to eddy current heating of their magnetic components, particularly the motor field pole-pieces that, for DC, would have used solid (un-laminated) iron and they are now rarely used.
What type of motor was used in trailway traction applications?

ANS: universal

QUES: Bond disobeys M's order and travels to Rome to attend Sciarra's funeral. That evening he visits Sciarra's widow Lucia, who tells him about Spectre, a criminal organisation to which her husband belonged. Bond infiltrates a Spectre meeting, where he identifies the leader, Franz Oberhauser. When Oberhauser addresses Bond by name, he escapes and is pursued by Mr. Hinx, a Spectre assassin. Moneypenny informs Bond that the information he collected leads to Mr. White, former member of Quantum, a subsidiary of Spectre. Bond asks her to investigate Oberhauser, who was presumed dead years earlier.
Where does Sciarra's funeral take place?

ANS: Rome

QUES: At the same time the order found itself face to face with the Renaissance. It struggled against pagan tendencies in Renaissance humanism, in Italy through Dominici and Savonarola, in Germany through the theologians of Cologne but it also furnished humanism with such advanced writers as Francesco Colonna (probably the writer of the Hypnerotomachia Poliphili) and Matteo Bandello. Many Dominicans took part in the artistic activity of the age, the most prominent being Fra Angelico and Fra Bartolomeo.
Which friars were celebrated in the science of the Renaissance age?

ANS: unanswerable

QUES: Despite competition from other materials, copper remains the preferred electrical conductor in nearly all categories of electrical wiring with the major exception being overhead electric power transmission where aluminium is often preferred. Copper wire is used in power generation, power transmission, power distribution, telecommunications, electronics circuitry, and countless types of electrical equipment. Electrical wiring is the most important market for the copper industry. This includes building wire, communications cable, power distribution cable, appliance wire, automotive wire and cable, and magnet wire. Roughly half of all copper mined is used to manufacture electrical wire and cable conductors. Many electrical devices rely on copper wiring because of its multitude of inherent beneficial properties, such as its high electrical conductivity, tensile strength, ductility, creep (deformation) resistance, corrosion resistance, low thermal expansion, high thermal conductivity, solderability, and ease of installation.
How much of mined copper is used for cables and electrical wiring?

ANS:
Roughly half
