Os cuerpos, de masas m1 = 2kg y m2 = 3kg, unidos por un cordón de masa despreciable, se deslizan sin fricción a lo largo de una rampa de altura h = 0.8 m y longitud L = 1.7 m. Calcule la aceleración de los bloques mientras descienden.

(a) calculate the number of electrons in a small, electrically neutral silver pin that has a mass of 10.0 g. silver has 47 electrons per atom, and its molar mass is 107.87 g/mol. (b) imagine adding electrons to the pin until the negative charge has the very large value 1.00 mc. how many electrons are added for every 109 electrons already present
