Mark all the leptons a) proton b) electron c)anti-top d) gluon e) tau neutrino

Electron, Tan Neutrino,

Explanation:

A lepton is an elementary particle of half-integer spin (spin 1⁄2) that does not undergo strong interactions. Two main classes of leptons exist, charged leptons (also known as the electron-like leptons), and neutral leptons (better known as neutrinos).

explanation:

as the height from which the ruler was dropped increased, the speed of the ruler at ryan's hand increased.
