3.A sprinkler with four identical arms is to be converted into a turbine to generate electric power by attaching a generator to its rotating head as show below. Water enters the sprinkler from the base along the axis of rotation at a rate of 20 L/s and leaves thenozzle in the tangential direction. The sprinkler rotates at a rate of 100 rpm in a horizontal plane. The diameter of each jet is 1 cm, and the normal distance between the axis of rotation and the center of each nozzle is 0.6 m. What is the torque associated with this rotation

The most important difference between a wedge and an inclined plane is a. their size b. their shape c. how they are used d. what they are made of

Light traveling in a medium with a refractive index 1.19 is incident on a plate of another medium with index of refraction 1.79. at what angle of incidence is the reflected light fully polarized?

Calculate the ratio of h+ ions to oh– ions at a ph = 6. find the concentration of h+ ions to oh– ions listed in table b of your student guide. then divide the h+ concentration by the oh– concentration. record this calculated ratio in table a of your student guide. compare your approximated and calculated ratios of h+ ions to oh– ions at a ph = 6. are they the same? why or why not? record your explanation in table a. what is the concentration of h+ ions at a ph = 6? mol/l what is the concentration of oh– ions at a ph = 6? mol/l what is the ratio of h+ ions to oh– ions at a ph = 6? : 1
