- Convert the following measurements to metric units with power-of-ten prefixes. Do not use scientific or engineering notation. Numeric values must range from 1 to less than 1000. Metric prefixes, which are case-sensitive, must be one of the following: M, m, c, k, or µ. (You may use lower-case 'u' in place of 'p'.) Example: 2.00 × 105 m = 200 km Enter the numeric value in the first box, and enter the metric prefix in the second box. a. 3.51 x 10-5 L = b. 7.98 x 108 J = C. -0.000230 W = - W d. 11,200 K = K (note: upper-case 'K' is the abbreviation for the temperature unit 'kelvin')An astronomical unit (AU) is the average distance between the Earth and the Sun, approximately 1.50 × 10° km. The speed of light is about 3.00 x 10° m/s. Express the speed of light in astronomical units per minute. Number Units7. A cylinder ħas á radius of 4.6 ± 0.4 cm and a height of 5.36 ± 0.3 cm.

- 1)A grocery store sells 5-lb bag of apples. A customer bought apples weekly and made a record of his purchases: The weighing scale in the grocery store has an uncertainty of 10.3 lb. The customer obtained the following measurements: Week 1: weight is 4.8 Ib Week 2: weight is 5.3 lb Week 3: weig is 4.9 Ib Week 4: weight is 5.4 lb What is the Percent Uncertainty of the bag's weight?Still think that unit conversion isn't important? Here is a widely publicized, true story about how failing to convert units resulted in a huge loss. In 1998, the Mars Climate Orbiter probe crashed into the surface of Mars, instead of entering orbit. The resulting inguiry revealed that NASA navigators had been making minor course corrections in SI units, whereas the software written by the probe's makers implicitly used British units. In the United States, most scientists use Sl units, whereas most engineers use the British, or Imperial, system of units. (Interestingly, British units are not used in Britain.) For these two groups to be able to communicate to one another, unit conversions are necessary. The unit of force in the SI system is the newton (N), which is defined in terms of basic Sl units as 1 N=1 kg · m/s?. The unit of force in the British system is the pound (lb), which is defined in terms of the slug (British unit of mass), foot (ft), and second (s) as 1 lb =1 slug ·…A new unit of measurement for long distances is introduced by superheroes into the scientific community.
