Your town is installing a fountain in the main square. if the water is to rise 26.0 m (85.3 feet) above the fountain, how much pressure must the water have as it moves slowly toward the nozzle that sprays it up into the air? assume atmospheric pressure equal to 100,000. pa and g=9.81 m/s2.

Write the equation for momentum, first using symbols for the variables, then using words for the variables.

Lin yao looks at the back of a spoon. how should she describe her reflection? upside down and smaller upside down and larger right-side up and smaller right-side up and larger

Arotating space station is said to create “artificial gravity”—a loosely-defined term used for an acceleration that would be crudely similar to gravity. the outer wall of the rotating space station would become a floor for the astronauts, and centripetal acceleration supplied by the floor would allow astronauts to exercise and maintain muscle and bone strength more naturally than in non-rotating space environments. if the space station is 200 m in diameter, what angular velocity would produce an “artificial gravity” of 9.80 m/s^{2} 2 at the rim?
