Take the absolute value of the difference between the two numbers. The difference between two numbers a and b is a-b or b-a. The absolute value is whichever one of these is not negative. So 0 - (-3) = +3 so the distance is 3 units.
The distance between two integers is the difference.
Retention Factor Rf == Distance traveled / total distance
The absolute value depends on it's "distance" from zero. So if it's to the right (positive) by 5 units, or to the left (negative) by five units, then it's absolute value is 5
The face value is 5, the place value is units.
+4 and -4 both do.
Wavelength is the distance between repeating units of a propagating wave of a given frequency. For light waves, this value is often given in nanometers, abbreviated as "nm". A nanometer is 0.000000001 meters.
The wavelength is the distance the wave travels before repeating in meters. The amplitude of the wave is the deflection from peak to trough in units of the wave value, e.g electric field or velocity.
Absolute Value means the distance from 0. I think of it as numbers on a number line, for instance -3 is 3 units from 0. So the absolute value of -99 would just be 99, because that is its distance from 0.
2.65: "Halfway" means that the distance from the smaller value to the halfway value equals the distance from the halfway value to the larger value.
What should you do to change a value in SI units to a value in U.S. customary units?
The distance between two numbers is the absolute value of their difference.
