Answer» Answer: A) SI is used in most places around the world, so our use of it allows scientists from disparate REGIONS to use a single standard in communicating scientific DATA without vocabulary confusion. B) In physics there are many quantities that cannot be expressed by a single base unit. THEREFORE, the unit of speed is the meter per second, or m/s. The unit meter per second is called a derived unit, MEANING that it is derived from the seven SI base units. |
