80 A N of M typically refers to "80 Ampere Newton meters," which is a unit of measurement commonly used in electrical and mechanical contexts. It combines electrical current (amperes) with torque (Newton meters), indicating the amount of torque produced by a device operating at a certain current level. This measurement can be important in applications such as electric motors or generators.
Let the number be 'm' & 'n' Hence Product ; mn = 80 Sum ; m + n = 21 m = 21 - n Substitute (21 - n) n = 80 21n - n^2 = 80 n^2 - 21 n + 80 = 0 It is now in quadratic form to factor. ( n - 16)(n - 5) = 0 Hence the numbers are 5 & 16
n * 4 = 80 Divide both sides by 4: n = 20

mn = 80 m -n = -79 Substitute m - 80/m = -79 m^2 - 80 = -79m m^2 + 79m = 80 (NB Notice change of signs) Quadratic Eq'n m = { - 79 +/- sqrt[)79)^2 - 4(1)(-80)}] / 2(1) m = { - 79 +/- sqrt[6241 + 320}]/ 2 m = { -79 +/- sqrt[6561]} / 2 m = { - 79 +/- 81}/2 m = -160 / 2 = -80 or m = 2/2 = 1 Hence n = 1 + 79 = 80

Agatha Christie's novel "N or M" takes its title from part of the catechism in the Book of Common Prayer, - "What is your Christian name? Answer N. or M."

Let the number by 'm' & 'n' Hence mn = 80 (product) m + n = 21 (sum) Hence m = 21 -b Substitute (21 - n)n = 80 21m - n^(2) = 80 n^(2) - 21n + 80 = 0 Factor (n - 16)(n - 5) = 0 Hence n= 16 & m = 5

As long as the stick remains in contact with the puck and the force on it continues,F = m AA = F/m = (40 / 0.5) = 80 m/sec2
To find the number of moles in 80 grams of calcium, you would first calculate the molar mass of calcium (40.08 g/mol), then divide the given mass by the molar mass to get the number of moles. In this case, 80 grams of calcium would be 2 moles.
