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.

a) It can dissolve other substances and has high specific heat capacity.

b) Pressure is transferred equally in all directions

c) F=14*0.04/0.02=28 N

d) I'd expect that it will sink cause weight will pull it to the bottom

e) Because the buoyant force is stipulated by difference between pressures in the top and bottom surfaces of a body.

f) Because this force increases in denser liquids: , where rho is density.

g) Q=Av, where v - speed, A - area. With the same flow rate v=Q/A, so larger area decreases speed and vice versa.

in this image, you can see solar radiation going through ocean water.

no image, but probably absorption

there is no correct list among the choices you've provided.

the list might look something like this:

-- baby human

-- piccolo

-- flute

-- soprano singer

-- trumpet

-- tenor singer

-- trombone

-- baritone singer

-- baritone horn

-- bass singer

-- tuba

since i had to make up the list myself, i made it easy on myself, and i didn't try to shuffle the string instruments and woodwinds into it too.
