Problem: Because the rotor is much lighter in weight (mass) than a conventional rotor formed from copper windings on steel laminations, the rotor can accelerate much more rapidly, often achieving a mechanical time constant under one ms. This is especially true if the windings use aluminum rather than the heavier copper. But because there is no metal mass in the rotor to act as a heat sink, even small coreless motors must often be cooled by forced air. Overheating might be an issue for coreless DC motor designs.
How does a coreless rotor compare to traditional rotors in terms of weight?
The answer is the following: lighter

Problem: The term Appalachian refers to several different regions associated with the mountain range. Most broadly, it refers to the entire mountain range with its surrounding hills and the dissected plateau region. The term is often used more restrictively to refer to regions in the central and southern Appalachian Mountains, usually including areas in the states of Kentucky, Tennessee, Virginia, Maryland, West Virginia, and North Carolina, as well as sometimes extending as far south as northern Alabama, Georgia and western South Carolina, and as far north as Pennsylvania, southern Ohio and parts of southern upstate New York.
What states comprise of the southern Appalachian mountains?
The answer is the following: Kentucky, Tennessee, Virginia, Maryland, West Virginia, and North Carolina

Problem: The Soviet answer on 4 May admonished Tito and the Communist Party of Yugoslavia (CPY) for failing to admit and correct its mistakes, and went on to accuse them of being too proud of their successes against the Germans, maintaining that the Red Army had saved them from destruction. Tito's response on 17 May suggested that the matter be settled at the meeting of the Cominform to be held that June. However, Tito did not attend the second meeting of the Cominform, fearing that Yugoslavia was to be openly attacked. In 1949 the crisis nearly escalated into an armed conflict, as Hungarian and Soviet forces were massing on the northern Yugoslav frontier. On 28 June, the other member countries expelled Yugoslavia, citing "nationalist elements" that had "managed in the course of the past five or six months to reach a dominant position in the leadership" of the CPY. The assumption in Moscow was that once it was known that he had lost Soviet approval, Tito would collapse; 'I will shake my little finger and there will be no more Tito,' Stalin remarked. The expulsion effectively banished Yugoslavia from the international association of socialist states, while other socialist states of Eastern Europe subsequently underwent purges of alleged "Titoists". Stalin took the matter personally and arranged several assassination attempts on Tito, none of which succeeded. In a correspondence between the two leaders, Tito openly wrote:
What was the name of those purged in other socialist states in Eastern Europe?
The answer is the following: Titoists

Problem: Schwarzenegger served in the Austrian Army in 1965 to fulfill the one year of service required at the time of all 18-year-old Austrian males. During his army service, he won the Junior Mr. Europe contest. He went AWOL during basic training so he could take part in the competition and spent a week in military prison: "Participating in the competition meant so much to me that I didn't carefully think through the consequences." He won another bodybuilding contest in Graz, at Steirer Hof Hotel (where he had placed second). He was voted best built man of Europe, which made him famous. "The Mr. Universe title was my ticket to America the land of opportunity, where I could become a star and get rich." Schwarzenegger made his first plane trip in 1966, attending the NABBA Mr. Universe competition in London. He would come in second in the Mr. Universe competition, not having the muscle definition of American winner Chester Yorton.
Which competition did Schwarzenegger go AWOL to participate in?
The answer is the following:
Junior Mr. Europe
