The moving magnet and conductor problem is a famous thought experiment, originating in the 19th century, concerning the intersection of classical electromagnetism and special relativity. In it, the current in a conductor moving with constant velocity, v, with respect to a magnet is calculated in the frame of reference of the magnet and in the ...
The paradox of a charge in a gravitational field is an apparent physical paradox in the context of general relativity. A charged particle at rest in a gravitational field, such as on the surface of the Earth, must be supported by a force to prevent it from falling. According to the equivalence principle, it should be indistinguishable from a ...
Coronal loop. In solar physics, a coronal loop is a well-defined arch-like structure in the Sun 's atmosphere made up of relatively dense plasma confined and isolated from the surrounding medium by magnetic flux tubes. Coronal loops begin and end at two footpoints on the photosphere and project into the transition region and lower corona.
The IBA's event, however, began an hour late and was riddled with technical problems and lengthy rants about issues unrelated to the fighters. There were boos and shouted questions.
The loop cost $53 million when it opened in June 2021 and is 40 feet (12 m) below ground. The two below-ground stations have escalators and elevators. The loop is 1.7 miles (2.7 km) in length and covers a 25-minute walking distance. The plan is for the cars to be autonomous vehicles in the future.

Hour record. The hour record is the record for the longest distance cycled in one hour on a bicycle from a stationary start. Cyclists attempt this record alone on the track without other competitors present. It is considered one of the most prestigious records in cycling. Since it was first set, cyclists ranging from unknown amateurs to well ...
The speed of light in vacuum, commonly denoted c, is a universal physical constant that is exactly equal to 299,792,458 metres per second (approximately 300,000 kilometres per second; 186,000 miles per second; 671 million miles per hour). [Note 3] According to the special theory of relativity, c is the upper limit for the speed at which ...
