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 *

A47.2 g block of copper whose temperature is 480 k is placed in an insulating box with a 91.8 g block of lead whose temperature is 200 k. (a) what is the equilibrium temperature of the two-block system? (b) what is the change in the internal energy of the two-block system between the initial state and the equilibrium state? (c) what is the change in the entropy of the two-block system? the heat capacities of copper and lead are 386 j/kg·k and 128 j/kg·k, respectively.
