econdary instruments are calibrated.absolute instruments are not calibrated.

secondary instruments are used everywhere,ab instru are only in labs or std institutions.

What is the difference between absolute pressure and gage pressure, and how do they relate to each other in terms of measuring pressure?

Absolute pressure is the total pressure exerted by a fluid, including atmospheric pressure. Gauge pressure is the pressure measured relative to atmospheric pressure. They are related by the equation: Absolute pressure Gauge pressure Atmospheric pressure.


What is the difference between an absolute threshold and a just noticeable difference?

An absolute threshold is the smallest amount of stimulation needed for a sensation to be detected, while a just noticeable difference is the smallest detectable difference between two stimuli. In other words, the absolute threshold is about detecting the presence of a stimulus, while the just noticeable difference is about discriminating between two stimuli.


What is the difference between absolute threshold and difference threshold?

absolute threshold is the lowest level that a person will feel sensation differential threshold is the minimal difference that a person can detect between two similar stimuli For example a change in volume in certain frequencies would be crossing the absolute threshold, how much that change would need to be for someone to detect it would be dealing with the difference threshold.


What is fourth scale for measuring temperature?

the fourth scale for measuring temperature is RANKINE...


What is the difference between kelvin and rankine?

Kelvin is a unit of temperature in the International System of Units (SI), based on the absolute zero point, where 0K is absolute zero. Rankine is a unit of temperature in the Imperial system, also based on absolute zero, where 0°R is absolute zero. The main difference is the scale used for measurement (Celsius for Kelvin and Fahrenheit for Rankine).

What is an absolute instrument?

An absolute instrument is an instrument whose calibration can be determined by means of physical measurements.


IF The weight of a rock is measured at 2.5 pounds what is the percent error in this measurement?

The percent error is calculated by taking the absolute difference between the measured value and actual value, dividing it by the actual value, and then multiplying by 100. If the actual weight is not provided, the percent error cannot be calculated.

What is kilopascal absolute?

A kilopascal is a thousand pascal - a unit of pressure. "Absolute" means the actual pressure - this is in contrast to measuring a pressure DIFFERENCE (usually, how much higher some pressure is, compared to atmospheric pressure).
