A water tower is a familiar sight in many towns. The purpose of such a tower is to provide storage capacity and to provide sufficient pressure in the pipes that deliver the water to customers. The drawing shows a spherical reservoir that contains 6.85 x 105 kg of water when full. The reservoir is vented to the atmosphere at the top. For a full reservoir, find the gauge pressure that the water has at the faucet in (a) house A and (b) house B. Ignore the diameter of the delivery pipes. The drawing shows a hydraulic chamber with a spring (spring constant = 1140 N/m) attached to the input piston and a rock of mass 37.0 kg resting on the output plunger. The piston and plunger are nearly at the same height, and each has a negligible mass. (c) By how much is the spring compressed from its unstrained position?
