Earth has many forms of rotation, one solar rotation is considered a solar day, loosely 24 hours. where as Earth's rotation around fixed points in space such as stars is called an interstellar day, about 23.93447191769194 hours.

How many revolutions of the disc in energy meter is taken as 1 unit?
The number of revolutions the disk in a kWh meter needs to make to produce a read increase of one unit (1 kWh) is 1000 divided by the disk constant. The disk in a meter with a 7.2 constant (Kh = 7.2) will have to make 138 and 8/9 revolutions to make the right most dial in the meter increase its read by one unit.
What is the SI unit for time period?
The SI unit for time is the second.
What are the metric units for time?
there is no real metric unit. The SI unit is the second
Higher unit of time is?
An era is a higher unit of time, as is a millenium, or century.
All measurements must consist of?
a unit of measurement along with the number
Why are the units of frequency expressed in reciprocal units?
Frequency is defined as the number of repetitions made in one second. In case of pendulum the repetition is called oscillation. In case of a tuning fork, the repetition is known to be vibration. In case of a wheel, the same repetition is said to be rotation. In case of planet going around the sun, that one is named as revolution. So, the number of oscillations, vibrations, rotations, revolutions per second in known as frequency. Thus, as the number has no unit and time has second as unit we get the unit for frequency as second -1
An automobile tire is rated to last for 50000 mi estimate the number of revolutions the tire will make in its lifetime?
The rotations per unit of a distance (mile, kilometer, etc.) of a tire are dependent on multiple variables. In order to answer (or even estimate) the size of the tire must be known. Tires can range in diameter from centimeters to meters in diameter.
Is the unit rate for 405 rotations in 5 minutes?
81 rpm

What is frequency of waves?
The number of circular revolutions made by the charged particle in one second. f=1/T unit of frequency is Hertz
The unit which frequency is measured?
Frequency is measured in Hertz (Hz). It means number of (what you're counting) per second. Ie. waves, revolutions, beats ect.
What is ment by angular velocity?
It is a measure of how fast something spins, but instead of a measure in meters per second, kilometers per hour, or some similar measurement of (distance/time), a unit of rotation is used, either (angle/time) or (revolutions/time), for example radians/second, degrees/hour, revolutions/minute, etc.
I want to go from gallons per minute to strokes per minute?
Strokes per minute is not a unit of capacity and hence, there is no correspondence with gallons per minute. Strokes per minute is comparable with rotations or revolutions per minute. SPM is normally used for reciprocating machines, to define the speed. A. R. Pathak
What is a frequencie?
Frequency is the number of occurrences of a repeating event per unit time
How many different rectangular prisms can you make with 16 unit cubes?
Ignoring rotations, there are 3 distinct solutions.
What unit represents 3 rpm?
The unit is 'rpm' which stands for revolutions per minute. Rpm can also be written as min-1.
Is the number of wave per unit of time?
Frequency.
