The ruler length and width measurements reflected the largest bias, regardless of wound shape [8]. The standard error of measurement (SEM) is defined as the difference between an observed score and a true score, so the SEM is an indication of the imprecision of a measurement technique [17].
Washington: Runaway planets zipping through space at mind-numbing speeds of 30 million miles per hour are now the fastest objects in the universe, says a study. Seven years ago, the discovery of the first runaway star, shooting out of our Galaxy at a staggering speed of 1.5 million mph, set astronomers on a course of exploration.
Ceres: The largest object that orbits in between Mars and Jupiter in the asteroid belt, Ceres has an average orbital speed of 17.822 kilometers per second. It was discovered in 1801 by the Italian monk and astronomer Giuseppe Piazzi. In 2006, Ceres was classified as a dwarf planet.
