You start at zero, the one marks an inch from the zero mark, signifying one inch
It is called the scale ruler.
Wavelength is a measure of distance not area. It is the distance traveled by a signal from a Zero state to a Plus One state back through Zero to Minus One and returning to Zero.
The distance from the number to zero (or the distance from zero to the number). Ignore the fact than one measure is positive and the other negative.
To record measurements using a ruler, place the ruler next to the object to be measured. Ensure that the zero mark on the ruler aligns with one end of the object. Read the measurement where the other end of the object falls on the ruler and record it in the appropriate units.
False
Using a ruler which marked by Centimeters will more helpful to measure the distance of a map.
On an inches ruler, you start measuring from the edge of the ruler. On a centimeter ruler, you begin measuring from the zero mark.
The distance travelled by a particle cannot be zero when displacement is not zero because unlike distance which is a scalar, displacement is a vector quantity implying that it has both direction and magnitude.
Yes, the distance travelled by a particle can be zero even when the displacement is not zero. This can happen when the particle moves back and forth along the same path, resulting in a net displacement of zero but no actual distance covered.
Hmm. Just place a ruler so one edge is at one corner and then swing the ruler around to the opposite corner and read the distance. Is that what you meant? Answer 2 Why don't you just put a ruler from corner to corner? Is that a problem?
On a metric ruler, that point is about 13.386 inches fromthe 'zero' end, whether or not there's a mark there.
