QUES: In a WRIM, the rotor winding is made of many turns of insulated wire and is connected to slip rings on the motor shaft. An external resistor or other control devices can be connected in the rotor circuit. Resistors allow control of the motor speed, although significant power is dissipated in the external resistance. A converter can be fed from the rotor circuit and return the slip-frequency power that would otherwise be wasted back into the power system through an inverter or separate motor-generator.

What can a resistor never control?

ANS: unanswerable
QUES: The state (like its southwestern neighbors) has had close linguistic and cultural ties with Mexico. The state outside the Gadsden Purchase of 1853 was part of the New Mexico Territory until 1863, when the western half was made into the Arizona Territory. The area of the former Gadsden Purchase contained a majority of Spanish-speakers until the 1940s, although the Tucson area had a higher ratio of anglophones (including Mexican Americans who were fluent in English); the continuous arrival of Mexican settlers increases the number of Spanish-speakers.

QUES: In contrast to the hazy, relatively featureless atmosphere of Uranus, Neptune's atmosphere has active and visible weather patterns. For example, at the time of the Voyager 2 flyby in 1989, the planet's southern hemisphere had a Great Dark Spot comparable to the Great Red Spot on Jupiter. These weather patterns are driven by the strongest sustained winds of any planet in the Solar System, with recorded wind speeds as high as 2,100 kilometres per hour (580 m/s; 1,300 mph). Because of its great distance from the Sun, Neptune's outer atmosphere is one of the coldest places in the Solar System, with temperatures at its cloud tops approaching 55 K (218 C). Temperatures at the planet's centre are approximately 5,400 K (5,100 C). Neptune has a faint and fragmented ring system (labelled "arcs"), which was first detected during the 1960s and confirmed by Voyager 2.

What weather did Voyager 2 observe on Neptune?
