Answer:
c is right
Explanation:
i have no reason
Answer:
1. Gases are more difficult to measure than liquids, because measured volumes are highly affected by temperature and pressure. Gas meters measure a defined volume, regardless of the pressurized quantity or quality of the gas flowing through the meter.
2. 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.
3. speed is derived unit becoz its unit is meter/second which is derived from 7 fundamental units.
Explanation:
4. Measurement tools make our lives better and safer, and they enhance the quality and quantity of life. Arguably, the ability to measure physical properties accurately has tremendous survival value that gives humans an adaptive, evolutionary advantage honed through many years of natural selection.
