A. water has many unique properties. identify a property of water and explain why this property makes water vital to living organism.
b. write one or two sentences that summarize pascal's principle.
c. a force of 14,00 n is exerted on a piston that has an area of 0.020 m^2. what is the force exerted by a second piston that has an area of 0.040 m^2.
d. an object's weight is greater than its buoyant force in water. what would you expect to happen when the object is placed in water? explain your answer.
e. a cannon is recovered from a shipwreck. why does the buoyant force on the cannon stay the same as long as it is fully under water? explain your reasoning.
f. an object sinks in both water and soil, so it displaces the same volume of each liquid. oi is less dense than water. why is the buoyant force acting on the object greater in water than it is in oil?
g. use the flow rate equation to explain how the motion of a whitewater raft changes as the river channel becomes narrower.

Certain bacteria (such as aquaspirillum magnetotacticum) tend to swim toward the earth’s geographic north pole because they contain tiny particles, called magnetosomes, that are sensitive to a magnetic field. if a transmission line carrying 100 a is laid underwater, at what range of distances would the magnetic field from this line be great enough to interfere with the migration of these bacteria? (assume that a field less than 5% of the earth’s field would have little effect on the bacteria. take the earth’s field to be 5.0 * 10-5 t, and ignore the effects of the seawater.)
