3. Comparing and Contrasting Water exerts pressure on all sides of a submerged submarine.
Compare and contrast the pressures acting on
the submarine at a depth of 50 m to the
pressures at a depth of 200 m.

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

Which changes of state do the labels represent? a: b: c:

Afeather of mass 0.001 kg falls from a height of 2 m. under realistic conditions, it experiences air resistance. based on what you know about friction, what can you say about the kinetic energy of the feather as it reaches the ground? acceleration due to gravity is g = 9.8 m/s2. a. ke < 0.0196 j b. ke = 00196 j c. je = 0 j d. ke > 0.0196 j
