Homonym: m (Meter)
The letter "m" is the 13th letter of the English alphabet. It is a consonant and is pronounced as /ɛm/. In the phonetic alphabet, it represents a voiced bilabial nasal sound, which means it is produced by closing both lips and allowing air to flow through the nose.
In mathematics, "m" is often used to represent a variable or a constant. For example, in the equation of a line, y = mx + b, "m" denotes the slope, indicating how steep the line is. Additionally, "m" can represent mass in physics, particularly in equations related to Newton's laws of motion.
