Question 9 why do scientists prefer to use the metric system? a. it allows for more accurate measurements b. it reduces systematic error. c. it reduces random error. d. it is based on invariant natural constants. e. calculations can be done using calculators

Option A.

Explanation:

It allows for more accurate measurements, is the right answer.

The scientists prefer to use the metric system due to the fact that through this they can accurately compare their findings. This system is used throughout the world to measure weight, volume and distance. In this system, there are three basic units of which all the others are measured; meters for length, grams for weight and seconds for time. In short, this system gives the same standards of measurement to the scientists at the time when they conduct experiments.

a maximum–minimum thermometer. the scales are fahrenheit on the inside of the u and celsius on the outside. the current temperature is 23 degrees celsius, the maximum recorded is 25, and the minimum is 15, both read from the base of the small markers in each arm of the u tube. the bulbs are hidden by a plastic housing.

six's thermometer is a registering thermometer which can record the maximum and minimum temperatures reached over a period of time, for example 24 hours. it is used to record the extremes of temperature at a location, for instance in meteorology and horticulture. it was invented by a british scientist james six, born in canterbury, in 1780; [1] the same basic design remains in use.

it is also commonly known as a maximum–minimum, minimum–maximum, maxima–minima or minima–maxima thermometer, of which it is the earliest practical design.

the thermometer indicates the current temperature, and the highest and lowest temperatures since last reset.
