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.)

Which of the following would not be taken into consideration when describing the quality of a sound

15. give an example for some particles or waves that are moving faster than light in everyday life 16. what is a laser? 17. what is an oscilloscope? 18. what does it means practically that nothing is faster than light in vacuum? 19. what is vacuum?

Asteam power plant operates on an ideal reheat rankine cycle between the pressure limits of 15 mpa and 10 kpa. the mass flow rate of steam through the cycle is 12 kg/s. steam enters both stages of the turbine at 500°c. if the moisture content of the steam at the exit of the low-pressure turbine is not to exceed 10 percent, determine (a) the pressure at which reheating takes place, (b) the total rate of heat input in the boiler, and (c) the thermal efficiency of the cycle. also, show the cycle on a t-s diagram with respect to the saturation lines.
