Lorenzo, tramite la fune d’acciaio del verricello montato sul frontale del suo fuoristrada, vuole trascinare un tronco d’albero con massa di 3,00 quintali poggiato su un terreno la cui superficie è inclinata di 30,0° rispetto all’orizzontale. Considera il fuoristrada fermo in alto sul terreno orizzontale, la fune parallela al terreno in pendio e l’albero in basso nel pendio. Si trascurino le forze di attrito. Calcola la forza minima che il verricello deve esercitare per poter trascinare il tronco. Es. di notazione scientifica: 3,2x10^4 *

Assume that two of the electrons at the negative terminal have attached themselves to a nearby neutral atom. there is now a negative ion with a charge -2e at this terminal. what are the electric potential and electric potential energy of the negative ion relative to the electron? the electric potential and the electric potential energy are both twice as much. the electric potential is twice as much and the electric potential energy is the same. the electric potential is the same and the electric potential energy is twice as much. the electric potential and the electric potential energy are both the same. the electric potential is the same and the electric potential energy is increased by the mass ratio of the oxygen ion to the electron. the electric potential is twice as much and the electric potential energy is increased by the mass ratio of the oxygen ion to the electron.
