my estimates that the water she is preparing for experiment is at 100 degrees celsius, but the actual temperature is 94.3 degrees celsius. What is her percent error

Percent error is 5.7%

Explanation:

What is percent error?

The percent error can be defined as the shift or diversion of the expected value from the actual value

let us use the following notations for our calculations

E=percent error

vA=actual value observed

vE=expected value

Therefore the percent error is 5.7%

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.
