  2. Tau (particle) - Wikipedia

    en.wikipedia.org/wiki/Tau_(particle)

    Tau (particle) The tau ( τ ), also called the tau lepton, tau particle, tauon or tau electron, is an elementary particle similar to the electron, with negative electric charge and a spin of ⁠ 1 2 ⁠. Like the electron, the muon, and the three neutrinos, the tau is a lepton, and like all elementary particles with half-integer spin, the tau ...

    Coaxial. Passband. DC - 6 GHz (12 GHz) Electrical. Max. voltage. 500 V RMS. The 4.3-10 connector (sometimes referred to as 4.3/10) is a 50 Ω multi-purpose RF connector used to connect coaxial cables with other cables or RF devices, such as transmitters or antennas. It was developed by a group of RF connector manufacturers, Huber+Suhner [ de ...

  5. Charged particle - Wikipedia

    en.wikipedia.org/wiki/Charged_particle

    A plasma is a collection of charged particles, atomic nuclei and separated electrons, but can also be a gas containing a significant proportion of charged particles. Charged particles are labeled as either positive (+) or negative (-). The designations are arbitrary. Nothing is inherent to a positively charged particle that makes it "positive ...

  6. Triboelectric effect - Wikipedia

    en.wikipedia.org/wiki/Triboelectric_effect

    e. The triboelectric effect (also known as triboelectricity, triboelectric charging, triboelectrification, or tribocharging) describes electric charge transfer between two objects when they contact or slide against each other. It can occur with different materials, such as the sole of a shoe on a carpet, or between two pieces of the same material.

  7. Two's complement - Wikipedia

    en.wikipedia.org/wiki/Two's_complement

    Two's complement is the most common method of representing signed (positive, negative, and zero) integers on computers, [1] and more generally, fixed point binary values. Two's complement uses the binary digit with the greatest value as the sign to indicate whether the binary number is positive or negative; when the most significant bit is 1 the number is signed as negative and when the most ...

    The partial sums of the series 1 + 2 + 3 + 4 + 5 + 6 + ⋯ are 1, 3, 6, 10, 15, etc.The nth partial sum is given by a simple formula: = = (+). This equation was known ...

  9. Rutherford scattering experiments - Wikipedia

    en.wikipedia.org/wiki/Rutherford_scattering...

    In his 1911 paper , Rutherford assumed that the central charge of the atom was positive, but a negative charge would have fitted his scattering model just as well. [34] In a 1913 paper, [ 35 ] Rutherford declared that the "nucleus" (as he now called it) was indeed positively charged, based on the result of experiments exploring the scattering ...
