la masa sostenida en la mano es de 6 kg. Suponga que la masa del antebrazo y la mano juntos es de 8 kg y que su centro de gravedad (C. G.) está donde se indica en la figura. ¿Cuál es la magnitud de la fuerza muscular (FM)? (g = 10 m/s2). Los ángulos respecto al eje de las X, y las distancias en relación a la articulación del codo y las fuerzas son: FM 50°, 5 cm; CG 30°, 10 cm y el ángulo de la masa 20°, 35 cm. Alguien ayúdeme por favor, necesito la respuesta lo antes posible, daré 25 puntos

Nacidified solution was electrolyzed using copper electrodes. a constant current of 1.18 a caused the anode to lose 0.584 g after 1.52 ✕ 103 s. given that the charge of an electron is 1.6022 ✕ 10−19 c, calculate avogadro's number. assume that copper is oxidized to cu2+ ions.
