A: a period measurement is done with a time start and a time stop, Most counters have this feature but not all of the counters. It provide time between events.
That can't be done. An acre is a measurement of area. A meter is a measurement of length.
Frequency means the number of occurrences within a given time period.
The scientific measurement for length is typically done using the metric system, where the unit of measurement is the meter. Other common units for length include centimeters, kilometers, and millimeters. Length can also be measured using non-metric units such as feet or inches in the imperial system.
In olden times, measurement was done using the body parts.
It is measurement done by megger tool of measurement .
To determine the frequency of a longitudinal wave, you can measure the number of complete oscillations the wave makes in a given time period. This can be done by calculating the cycles per second, which is the frequency of the wave in hertz (Hz). You can also use the wave's wavelength and speed to calculate its frequency using the formula: frequency = speed / wavelength.
The measurement of work done is the same measure we use for energy output. This measurement is called the joule and is symbolized simply by the letter j.
A meter stick is used to measure length and short distances. A meter stick is between 1.00m and 1.05m long. It is calibrated in cm and mm, which are the units it is used to measure. Measurement of distances of a number of meters was traditionally done with surveyor's tapes or chains; nowadays by interferometry using a laser. Ultra high precision measurement is mostly still done with a Fabry-Perot interferometer.
Frequency agility is the capacity for a radar to shift its frequency to account for things like atmosphere and jamming. Much of how its done has to do with the computer systems attached to the device running their calculations.
This cannot be done. A cubic meter is a volume and a square meter is an area.
250 mm is equal to 0.25 meters. This conversion can be done by dividing the millimeter measurement by 1000 (since there are 1000 mm in a meter).
In the SI, the square meter is derived from the meter (meter x meter). But in general, which units are derived and which are base units really depends on the system of measurement chosen. You could define a unit of area as a base unit, and derive a length as the square root of that - although I don't think any serious system of units has actually done that so far.
