The time from New Moon to Last Quarter is 22.15 days.
It would take 7 days
I would expect that period of time to comprise 3/4 of a full cycleof phases, or about 22.15 days.
The half life of Tritium is 12.32 years. it would therefore take 24.64 years for the amount to fall to a quarter of the original.
No, both a dime and a quarter would fall at the same rate in a vacuum due to gravity. The weight and size of the coins would not significantly affect the rate at which they fall.
A value that is between a quarter and a half is one third (1/3). In decimal form, a quarter is 0.25, a half is 0.5, and one third is approximately 0.333. Other values that also fall within that range include 0.26 to 0.49.
The average number of days between the last spring frost and the first fall frost varies depending on location, typically ranging from 120 to 180 days in temperate climates. This period is known as the growing season and is crucial for determining plant growth and crop productivity.
A quarter and and a pencils have little air friction and would not observed to fall at different velocity in normal classroom condition. It will be observed to fall to the ground at the same time.
The year is 365 and a quarter days long so to compensate there is a leap year every 4 years. Otherwise after a while the calendar year would fall out of synch with the seasons. At some point, summer vacation would happen during the snowy part of the year.

In a vacuum, a feather and a quarter would fall at the same rate due to gravity's influence. However, in normal conditions with air resistance, the feather falls slower since it has a larger surface area, creating more air resistance.
