Una masa en un plano inclinado está unida a otra masa colgante mediante una cuerda y una polea como se muestra en la figura. La masa en el plano inclinado es de 0.5K g, la masa colgante es de 0.3Kg, el ángulo es de 30° y el coeficiente de rozamiento es 0,2. Calcular: a) La aceleración del sistema. b) La tensión de la cuerda .Nota :(MOVIMIENTO EN SENTIDO HORARIO)

How can you improve the percent yield of copper in this lab? check all possible strategies that will you do so. measure reactants precisely. stir to the reaction take place. chill the reactants before combining them. wait patiently until the reaction completes. make sure to recover as much copper as possible.
