Use an example to explain how the available tools can affect the precision of a measurement.

Measuring weight, that is, mass under gravity, is an obvious way to demonstrate how available tools can affect the precision of a measurement. If you had access to a bathroom scale, you would not effectively be able to measure 7 grams of yeast to make a loaf of bread, as the scale is not precise enough. It can, however, easily differentiate the weight of a 78-kilogram male and a 65-kilogram female. The scale is precise enough for higher masses, but not precise enough for the small amounts of yeast needed to make a good loaf of bread.

Neptune is the eighth planet from the sun. it was the first planet to get its existence predicted by  mathematical calculations  before it was actually seen through a telescope on sept. 23, 1846. irregularities in the orbit of  uranus  led french astronomer alexis bouvard to suggest that the gravitational pull from another celestial body might be responsible. german astronomer johann galle then relied on subsequent calculations to   spot neptune via telescope. previously, astronomer galileo galilei sketched the planet, but he mistook it for a star due to its slow motion. in accordance with all the other planets seen in the sky, this new world was given a name from greek and roman mythology — neptune, the roman god of the sea.
