Abeam with a weight of 100 n nd a length of 12.0 meters is supported at each end. it is supporting a machine with a weight of 1800 n which is located 5.0 m from the left end of the beam. a.) draw a free body diagram for the beam, clearly labeling lol forces, write down the equations which are obtained from newton’s second law. b.) what is the force of support at the right end? c.) what is the force of support at the left end?

In a stagnant pool of water, a crayfish may spend much of its time lying with one side of its carapace near the surface of the water. in this position, it will move the walking legs on that side in a rhythmic back-and-forth motion. explain the likely function of this behavior.

This is for my 8th grade science class, i really don’t understand. can someone me? , lol.

Two manned satellites approaching one another at a relative speed of 0.550 m/s intend to dock. the first has a mass of 2.50 ✕ 103 kg, and the second a mass of 7.50 ✕ 103 kg. assume that the positive direction is directed from the second satellite towards the first satellite. (a) calculate the final velocity after docking, in the frame of reference in which the first satellite was originally at rest.(b) what is the loss of kinetic energy in this inelastic collision? (c) repeat both parts, in the frame of reference in which the second satellite was originally at rest. final velocity(d) loss of kinetic energy = ?
