Base your answers to questions 4 through 6 on the graph below and on your knowledge of Earth science. The graph shows the discharge of the Delaware River at Barryville, New York, for a one week
period during March 2004

4. Identify the date shown on the graph when the river was most likely carrying the greatest
amount of sediment AND EXPLAIN YOUR ANSWER. Hint: What is dischargo?
5. State one possible cause for the increase in stream discharge on March 15.
6. The Delaware River flows out of the Catskills and into the Atlantic Ocean. Identify the general
compass direction toward which the Delaware River flows along the Pennsylvania New York
State border. (Hint, if you want one: look at page 2 of the Reference Tables to locate the

a gas, having a molecular weight of 13 kg/kmol and a kinematic viscosity of 0.25 cm2/s, flows through a pipe 0.25 m internal diameter and 5 km long at the rate of 0.4 m3/s and is delivered at atmospheric pressure.

it can be observed without changing the identity of the object.

it depends on what substance you're talking about as well as many other factors. in quantum mechanics, the observation of particles affects the observers ability to measure certain properties. for example: you can know the velocity of a particle, but you can't know it's position; or you can know it's position, but not it's velocity. it's like trying to find out where a grain of sand is by throwing other grains of sand at it. once you find out where it is, it's been moved. it's also like trying to find an answer to the question of whether or not a tree falling in a forest makes a sound if nobody is there to hear it. paradoxically, the only way to find out is to be there and hear it.
