An F1 car can be no more than 200 cm wide and 95 cm tall. [1] Though there is no maximum length, other rules set indirect limits on these dimensions, and nearly every aspect of the car carries size regulations; consequently the various cars tend to be very close to the same size. The car and driver must together weigh at least 798 kg as of 2024.
List of reagent testing color charts. It is advised to check the references for photos of reaction results. [1] Reagent testers might show the colour of the desired substance while not showing a different colour for a more dangerous additive. [2] For this reason it is essential to use multiple different tests to show all adulterants.
Marquis reagent test analysis Substance Color Time (s) Notes MDMA or MDA: purple to black 0–5: May have dark purple tint Amphetamine, or methamphetamine: orange to brown 0–5: May have a brown tint 2C-B: yellow to green 5–10: Color may change from initial result: DXM: gray to black 15–30: Initially no change; takes much longer to reach ...
The iodine clock reaction is a classical chemical clock demonstration experiment to display chemical kinetics in action; it was discovered by Hans Heinrich Landolt in 1886. [1] The iodine clock reaction exists in several variations, which each involve iodine species ( iodide ion, free iodine, or iodate ion) and redox reagents in the presence of ...

Mental chronometry is the scientific study of processing speed or reaction time on cognitive tasks to infer the content, duration, and temporal sequencing of mental operations. Reaction time (RT; also referred to as " response time ") is measured by the elapsed time between stimulus onset and an individual's response on elementary cognitive ...
A flame test is relatively quick test for the presence of some elements in a sample. The technique is archaic and of questionable reliability, but once was a component of qualitative inorganic analysis. The phenomenon is related to pyrotechnics and atomic emission spectroscopy. [1] The color of the flames is understood through the principles of ...
Safety car. In motorsport, a safety car, or a pace car, is an automobile which limits the speed of competing cars or motorcycles on a racetrack in the case of a caution period such as an obstruction on the track or bad weather. The aim of the safety car is to enable the clearance of any obstruction under safer conditions, especially for ...
