Calcule la tensión en el cable y la compresión en el aguilón ligero de la figura 1,4 R. A = 43,2 N, B = 34,5 N 6. Calcule la tensión en las cuerdas A y B de la figura 1,6. R. A = 1 405 N, B = 1 147 N 7. Calcule la compresión en el puntal central B y la tensión en la cuerda A en la situación que se describe en la figura 1,5. R. A =643 N, B = 940 N 8. Dos pesas cuelgan de dos poleas sin fricción como se observa en la figura 1,5 ¿Qué peso W hará que el bloque de 300 N apenas empiece a moverse hacia la derecha? Supongamos que s = 0,3. R. 108 N 9. Encuentre el peso máximo que es posible colgar del punto O, tal como aparece en la figura 1,7 sin alterar el equilibrio. Suponga que s = 0,3 entre el bloque y la mesa. R. 21,8 N

(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
