An object is undergoing uniform circular motion. which of the following changes would increase the period of the motion? i. increase the radius of the circular motion. ii. decrease the radius of the circular motion. iii. increase the speed of the object. iv. decrease the speed of the object.

Water flows through a garden hose which is attached to a nozzle. the water flows through hose with a speed of 2.19 m/s and through the nozzle with a speed of 19.8 m/s. calculate the maximum height (in m) to which water could be squirted if it emerges from the nozzle and emerges with the nozzle removed.
