What is the scientific definition of day?

Answer 1

It is the 24 hour period, for planet Earth.

An hour is 60 minutes

and 1 minute equals 60 seconds.

24 hours is called the "solar day". It depends on the Sun's position in the sky.

There are other definitions of "day"

The "sidereal day" is equal to the Earth's rotation period.

That's about 4 minutes less than the solar day.

That's because the solar day depends on the Earth's motion around the Sun as well as Earth's rotation.

Other planets have their own day lengths.

Answer 2

A dais is simply a platform (typically raised) on which something or someone is placed so as to be easily viewed. Interestingly, the term is applied to platforms ranging from small wedding cake dais on which the bride and groom statuette is placed to a large platform on which persons are found who will be addressing a large audience. Landscaping makes use of a dais on which a statute or fountain or some such other decorative item is placed. It is also a family name and a type of tree. df, Calgary, AB.
