Someone on this? i just need the diagram to be drawn. a water-skier is pulled behind a boat by a rope that is at an angle of 13° and has a tension of 490 n. the water-skier has a mass of 49 kg. draw a free-body diagram showing the forces acting on the skier. (she is being pulled to the right.)

Trumpeter a holds a b-flat note on the trumpet for a long time. person c is running towards the trumpeter at a constant velocity. person b is running away from the trumpeter at the same rate. person d is standing still the whole time. which person hears a frequency that is lower than the b-flat?

Asatellite component is in the shape of a cube with 10cm edges, has an evenly distributed mass of 2 kg and one bolt hole at each of four corners. if the maximum predicted random vibration environment is 10 grms, what bolt size would be a good choice for restraint? what other factors might drive bolt size besides force/stress?
