The constants listed here are known values of physical constants expressed in SI units; that is, physical quantities that are generally believed to be universal in nature and thus are independent of the unit system in which they are measured.
It was created by Hungarian Márton Bukovi, who turned the 3–2–2–3/WM formation into a 3–2–3–2 by effectively turning the forward "M" upside down (that is M to W). [9] The lack of an effective centre-forward in Bukovi's team necessitated moving a forward back to midfield to create a playmaker, with another midfielder instructed to ...
The effect is used in a qualitative way and describes the electron withdrawing or releasing properties of substituents based on relevant resonance structures and is symbolized by the letter M. [2] The mesomeric effect is negative ( –M ) when the substituent is an electron-withdrawing group , and the effect is positive ( +M ) when the ...
The total area of the field is 57,600 sq ft or 5,350 m 2. There is a goal centered on each end line, with a crossbar 10 feet (3.0 m) above the ground and goalposts 18 feet 6 inches (5.64 m) apart (in college and the NFL) extending at least 35 feet (11 m) above the crossbar. Between the goal lines, additional lines span the width of the field at ...
The size of a football is roughly 22 cm (8.66 inches) in diameter for a regulation size 5 ball. Rules state that a size 5 ball must be 68 to 70 cm (27 to 28 in) in circumference. [19] Averaging that to 69 cm (27 in) and then dividing by π gives a diameter of about 22 cm (8.7 in).
Zdeno Chára, at 6 ft 9 in (2.06 m), is the tallest player ever to play in the NHL. In recent years, the height of goaltenders has increased as taller goaltenders can cover a larger portion of the goal when on their knees in the butterfly goaltending style. Mikko Koskinen at 6 ft 7 in (2.01 m) is the tallest goaltender currently in the NHL.
Adidas Tricolore, the official ball for the 1998 World Cup. Law 2 of the game specifies that the ball is an air-filled sphere with a circumference of 68–70 cm (27–28 in), a weight of 410–450 g (14–16 oz), inflated to a pressure of 0.6 to 1.1 atmospheres (60–111 kPa or 8.7–16.1 psi) "at sea level", and covered in leather or "other suitable material".

Ortho effect is an organic chemistry phenomenon where the presence of a chemical group at the at ortho position or the 1 and 2 position of a phenyl ring, relative to the carboxylic compound changes the chemical properties of the compound.
