Awater 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 3.88 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.

Two horses begin at rest. after a few seconds, horse a is traveling with a velocity of 10 m/s west, while horse b is traveling with a velocity of 13 m/s west. which horse had a greater acceleration? a. horse a because its change in velocity was greater than horse b's in the same time. b. horse b because its change in velocity was greater than horse a's in the same time. c. horse b because its change in velocity was the same as horse a's, but it took less time. d. both horses had the same acceleration.
