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

True or false: the cycle of seasons on the earth is caused by the tilt of the earth on its axis toward and away from the sun.

Match each scenario to the form of energy it represents

In the future, people will only enjoy one sport: electrodisc. in this sport, you gain points when you cause metallic discs hovering on a field to exchange charge. you are an electrodisc player playing the popular four disc variant. the disks have charges of qa = −8.0 µc, qb = −2.0 µc, qc = +5.0 µc, and qd = +12.0 µc. (1) you bring two disks together and then separate them. you measure the resulting charge of these two disks and find that it is +5.0 µc per disk. which two disks did you bring together? (a) a and b (b) a and c (c)a and d (d)b and c(e) b and d (f) c and d. (2) you bring three disks together and then separate them. you measure the resulting charge of these three disks and find that it is +3.0 µc per disk. which three disks did you bring together? a, b, and c (a) a, b, and d (c) a, c, and d (d) b, c, and d. (3) given the resulting charge of each disk measured in (b) is +3.0 µc, how many electrons would you need to add to a disk of this charge to electrically neutralize it? electrons
