False
The unit for a rate is the unit for the numerator divided by the unit for the denominator. For example, speed = distance divided by time. If distance is measured in micrometres and time in hours, then the units for speed are micrometres per hour.
(any unit of length or distance) divided by (any unit of time)2can be a unit of acceleration.
No the second is broken down into smaller intervals of time.
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.
Talking of Unit of Time then no doubt it is second. But measuring time in larger units are minute
No.
False
The smallest unit of time on the geologic time scale is an epoch, which typically lasts millions of years. It is used to divide periods into smaller segments based on significant changes in Earth's history.
False.
The measurement of Earth's history divided into time periods is called the geological time scale. It is divided into eons, eras, periods, epochs, and ages, with each unit representing a significant change in Earth's geological and biological history.
(Any unit of length) divided by (any unit of time) is a unit of speed.
(Any unit of length) divided by (any unit of time) is a unit of speed.
The SI unit is meters/second2 (meters/second/second). Any other unit of length divided by a time unit squared (or even a unit of length divided by two different time units) will do as well.
(Any unit of length) divided by (any unit of time) is a unit of speed.
minimal meaningful language unit;it cannot be divided into smaller meaningful units
(Any unit of length) divided by (any unit of time) is a perfectly good unit of speed.
