in morse code which letter is represented by a single dot
Morse code Each Morse code symbol represents either a text character (letter or numeral) or a prosign and is represented by a unique sequence of dots and dashes. The duration of a dash is three times the duration of a dot. Each dot or dash is followed by a short silence, equal to the dot duration. The letters of a word are separated by a space equal to three dots (one dash), and the words are separated by a space equal to seven dots. The dot duration is the basic unit of time measurement in code transmission.[1] To increase the speed of the communication, the code was designed so that the length of each character in Morse varies approximately inversely to its frequency of occurrence in English. Thus the most common letter in English, the letter "E", has the shortest code, a single dot.
Hermitian matrix The diagonal elements must be real, as they must be their own complex conjugate.
Pi Ï€ is commonly defined as the ratio of a circle's circumference C to its diameter d:[9]
IEEE 754-1985 The leading 1 bit is omitted since all numbers except zero start with a leading 1; the leading 1 is implicit and doesn't actually need to be stored which gives an extra bit of precision for "free."
Swallowing 5) Closure of the nasopharynx
Coulomb It is equivalent to the charge of approximately 7018624200000000000♠6.242×1018 (6995103600000000000♠1.036×10−5 mol) protons, and −1 C is equivalent to the charge of approximately 7018624200000000000♠6.242×1018 electrons.
