Question: Her first acting role of 2006 was in the comedy film The Pink Panther starring opposite Steve Martin, grossing $158.8 million at the box office worldwide. Her second film Dreamgirls, the film version of the 1981 Broadway musical loosely based on The Supremes, received acclaim from critics and grossed $154 million internationally. In it, she starred opposite Jennifer Hudson, Jamie Foxx, and Eddie Murphy playing a pop singer based on Diana Ross. To promote the film, Beyonce released "Listen" as the lead single from the soundtrack album. In April 2007, Beyonce embarked on The Beyonce Experience, her first worldwide concert tour, visiting 97 venues and grossed over $24 million.[note 1] Beyonce conducted pre-concert food donation drives during six major stops in conjunction with her pastor at St. John's and America's Second Harvest. At the same time, B'Day was re-released with five additional songs, including her duet with Shakira "Beautiful Liar".
Is there an answer to this question: What did Beyonce call her first concert tour?

Answer: The Beyonce Experience

Question: When used with a load that has a torque curve that increases with speed, the motor will operate at the speed where the torque developed by the motor is equal to the load torque. Reducing the load will cause the motor to speed up, and increasing the load will cause the motor to slow down until the load and motor torque are equal. Operated in this manner, the slip losses are dissipated in the secondary resistors and can be very significant. The speed regulation and net efficiency is also very poor.
Is there an answer to this question: How efficient is such a design?

Answer: very poor

Question: An armed rebellion beginning in 1956 by the African Party for the Independence of Guinea and Cape Verde (PAIGC) under the leadership of Amilcar Cabral gradually consolidated its hold on then Portuguese Guinea. Unlike guerrilla movements in other Portuguese colonies, the PAIGC rapidly extended its military control over large portions of the territory, aided by the jungle-like terrain, its easily reached borderlines with neighbouring allies, and large quantities of arms from Cuba, China, the Soviet Union, and left-leaning African countries. Cuba also agreed to supply artillery experts, doctors, and technicians. The PAIGC even managed to acquire a significant anti-aircraft capability in order to defend itself against aerial attack. By 1973, the PAIGC was in control of many parts of Guinea, although the movement suffered a setback in January 1973 when Cabral was assassinated.
Is there an answer to this question: When did the armed rebellion begin?

Answer: 1956

Question: A commutator is a mechanism used to switch the input of most DC machines and certain AC machines consisting of slip ring segments insulated from each other and from the electric motor's shaft. The motor's armature current is supplied through the stationary brushes in contact with the revolving commutator, which causes required current reversal and applies power to the machine in an optimal manner as the rotor rotates from pole to pole. In absence of such current reversal, the motor would brake to a stop. In light of significant advances in the past few decades due to improved technologies in electronic controller, sensorless control, induction motor, and permanent magnet motor fields, electromechanically commutated motors are increasingly being displaced by externally commutated induction and permanent-magnet motors.
Is there an answer to this question: What two motor types are descendant today?

Answer:
unanswerable
