  3. Formula 4 - Wikipedia

    en.wikipedia.org/wiki/Formula_4

    Formula 4 is the first step out of karting on the FIA Global Pathway, and by design has the least performance of any of the cars in it. Compared to road-legal supercars, Formula 4 cars are less accelerative and have a much lower top speed of approximately 240 km/h; most modern supercars are capable of in excess of 300 km/h. The F4 cars have far ...

    The zeros of the curve + =, are, making use of the quadratic formula, = /, or = / and (/ = / = ¯ and ). In terms of the dimensionless variables, T r , p r {\displaystyle T_{r},p_{r}} the zeros are at T r = 3 / 4 {\displaystyle T_{r}=3/4} and 27 / 4 {\displaystyle 27/4} , while the maximum is p r m a x = 9 {\displaystyle p_{r{\rm {max}}}=9 ...

  6. Molar concentration - Wikipedia

    en.wikipedia.org/wiki/Molar_concentration

    Molar concentration or molarity is most commonly expressed in units of moles of solute per litre of solution. [2] For use in broader applications, it is defined as amount of substance of solute per unit volume of solution, or per unit volume available to the species, represented by lowercase : [3]

  7. Number density - Wikipedia

    en.wikipedia.org/wiki/Number_density

    Using the number density as a function of spatial coordinates, the total number of objects N in the entire volume V can be calculated as = (,,), where dV = dx dy dz is a volume element. If each object possesses the same mass m 0 , the total mass m of all the objects in the volume V can be expressed as m = ∭ V m 0 n ( x , y , z ) d V ...

    Continuous charge distribution. The volume charge density ρ is the amount of charge per unit volume (cube), surface charge density σ is amount per unit surface area (circle) with outward unit normal n̂, d is the dipole moment between two point charges, the volume density of these is the polarization density P.

  9. Microcanonical ensemble - Wikipedia

    en.wikipedia.org/wiki/Microcanonical_ensemble

    Unfortunately, the energy flow between the two systems cannot be predicted based on the initial T s. Even when the initial T s are equal, there may be energy transferred. Moreover, the T of the combination is different from the initial values. This contradicts the intuition that temperature should be an intensive quantity, and that two equal ...
