Context: Death from laughter is a rare form of death, usually resulting from cardiac arrest or asphyxiation, caused by a fit of laughter. Instances of death by laughter have been recorded from the times of ancient Greece to the modern day.
 Question: can you have a heart attack from laughing Context: A pendulum is a weight suspended from a pivot so that it can swing freely. When a pendulum is displaced sideways from its resting, equilibrium position, it is subject to a restoring force due to gravity that will accelerate it back toward the equilibrium position. When released, the restoring force acting on the pendulum's mass causes it to oscillate about the equilibrium position, swinging back and forth. The time for one complete cycle, a left swing and a right swing, is called the period. The period depends on the length of the pendulum and also to a slight degree on the amplitude, the width of the pendulum's swing.
 Question: does the period of a pendulum depend on the initial angle Context: For a person standing in an elevator either stationary or moving at constant velocity, the normal force on the person's feet balances the person's weight. In an elevator that is accelerating upward, the normal force is greater than the person's ground weight and so the person's perceived weight increases (making the person feel heavier). In an elevator that is accelerating downward, the normal force is less than the person's ground weight and so a passenger's perceived weight decreases. If a passenger were to stand on a weighing scale, such as a conventional bathroom scale, while riding the elevator, the scale will be reading the normal force it delivers to the passenger's feet, and will be different than the person's ground weight if the elevator cab is accelerating up or down. The weighing scale measures normal force (which varies as the elevator cab accelerates), not gravitational force (which does not vary as the cab accelerates).
 Question: is weight always equal to the normal force Context: Hoosiers is a 1986 sports film written by Angelo Pizzo and directed by David Anspaugh in his feature directorial debut. It tells the story of a small-town Indiana high school basketball team that wins the state championship. It is loosely based on the Milan High School team that won the 1954 state championship.
 Question: is the film hoosiers based on a true story Context: A number of states expressed concern over the unilateral character of Kosovo's declaration, or explicitly announced that they would not recognise an independent Kosovo. The United Nations Security Council (UNSC) remains divided on this issue: of its five members with veto power, three (the United States, the United Kingdom, and France) have recognised the declaration of independence, while the People's Republic of China has expressed concern, urging the continuation of the previous negotiation framework. The Russian Federation has rejected the declaration and considers it illegal. On 15 May 2008, Russia, China, and India released a joint statement calling for new negotiations between Belgrade and Pristina.
