The smallest unit to measure length is?
The smallest unit is the Planck Length. Theoretically, it is not that there can be nothing smaller, but for various reasons that have nothing to do with the limits of technology there is nothing that can be known about anything that happens to be smaller. For scale, the number of Planck Lengths in the diameter of a proton is 10 to the twentieth power.
How fast is Planck time?
Planck length and Planck time Planck time is the time it would take a photon moving at the speed of light in a vacuum to cross a distance equal to the Planck length. The Planck length is 1.616252 × 10−35 meters, and the Planck time is 5.39121 × 10−44 seconds. Links are provided to the relevant Wikipedia articles.
Is there a unit smaller than a yoctometer?
Yes, there are units smaller than a yoctometer. The yoctometer (10^-24 meters) is part of the metric system, and smaller units can be defined using scientific notation, such as zeptometer (10^-21 meters) or even smaller hypothetical units, like the Planck length, which is approximately 1.616 x 10^-35 meters. However, these smaller units are primarily theoretical and not commonly used in practical measurements.
How many planck times are there in one second?
One second contains approximately ( 5.39 \times 10^{42} ) Planck times. The Planck time, which is about ( 5.39 \times 10^{-44} ) seconds, is the time it takes for light to travel one Planck length. Therefore, when you divide one second by the duration of a Planck time, you arrive at this vast number.
What is the name of a rectangle that has width of 9 and length of 5?
It has no specific name. It is unusual, though, because its length is smaller than its width!
