Medical laboratory technologists (commonly known as medical laboratory scientists) and medical laboratory technicians collect samples and perform tests to analyze body fluids, tissue, and other substances.owever, technologists perform more complex tests and laboratory procedures than technicians do. For example, technologists may prepare specimens and perform manual tests that are based on detailed instructions, whereas technicians perform routine tests that may be more automated.
But how fast does the Earth rotate? You might be surprised to know that a spot on the surface of the Earth is moving at 1675 km/h or 465 meters/second. Thatâs 1,040 miles/hour. Just think, for every second, youâre moving almost half a kilometer through space, and you donât even feel it.
To see this, we will calculate the linear velocity of a point on the surface of the Earth and a point on the tip of a fan blade. The radius of the Earth is approximately 4000 miles. The Earth is rotating at a rate of per hour. Therefore, the angular velocity of the Earthâs rotation is. 2  A second example is that of a ceiling fan. 3  If the fan rotates 30 times per minute, the angular velocity is radians per minute or. 4  The radius of the Earth is approximately 4000 miles. 5  The Earth is rotating at a rate of per hour.
