Rotation of bar oa is controlled by the lead screw which imparts a horizontal velocity v = 36 mm/s to collar c and causes pin p to travel along the smooth slot. the velocity of collar c is decreasing at a rate of 5 mm/s2 at the instant in question. determine the values of r¨ and θ¨, where r = op¯, if h = 240 mm and x = 190 mm

hurricanes form when warm, moist air from the ocean surface quickly rises into the atmosphere and forms storm clouds and rain. when the clouds are formed, heat is released which warms the cool air in the upper regions of the atmosphere so that the cycle can continue. which two phases of the water cycle are repeated in this process?
