Launching Startups from Universitiesatively charged. In a material that is an electrical conductor, such as copper, aluminum, and a number of other metals, it is possible for certain of the electrons to move from atom to atom along the conductor. The force that can cause these electrons to move along the conductor is called a voltage, or electromotive force (emf).calamity 发表于 2025-3-29 02:10:17
Early-Stage and Debt-Free Startups of atoms, by interactions between and among atoms. Chemical reactions involve changing partners among the atoms. This is not to say that atoms are the smallest of particles, or to say they cannot be subdivided. Rather, it states only that our daily experience involves changes between or among atoms, but does not involve subdivision of the atoms.全能 发表于 2025-3-29 04:38:57
