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.
exists and is an alternate of . Light is the fastest thing on earth. Light travels about 186,282 miles (more than seven times the circumference of Earth) in one second. In modern physics, light is regarded as the fastest thing in the universe, and its velocity in empty space as a fundamental constant of nature denoted by c.
