A distance is a measurement, and does not change based on which location is the starting point. (Unlike physics where the direction is considered)
The most appropriate SI unit to express the speed of a cyclist in the last leg of a 10-km race would be meters per second (m/s) since it provides a precise measurement of distance covered per unit time. This would allow for accurate calculation and comparison of speed.
Kilograms are used to express the metric measurement of mass.
The relationship between a and b is the same as c and d Which of the following IS an appropriate way to express any analogy? All of the above are correct.
The relationship between A and B is the same as C and D.
1.5 x 1011 meters = 1.5 x 108 kilometers
speed =distance/speed .units to express speed are m/s and km/hr.
405 miles is equal to 651.8 kilometers.
in meters
The two parts required to express measurement of a physical quantity are a numerical value and a unit of measurement. The numerical value indicates the magnitude of the quantity being measured, while the unit of measurement provides the context or scale for that value.
In general, the level of measurement is on an interval scale (temperature in deg C or F) because the zero point is arbitrary. However, if the zero is unique and non-arbitrary, then it is a ratio scale (temperature in Kelvin).
The light year is used to measure distances that are greater than our solar system. It is the next form of measurement above the Au, or astronomical unit, or the distance between the Earth and and the sun. It is normally used to measure distances between stars or galaxies. The light year is equivalent to 5,878,625,373,183.61 miles or 9,460,730,472,580.81 km. See the related link for more information.
