5) A net force of 12 Newtons acting north on an object for 4.0 seconds will produce an impulse of A) 3.0 kg-m/sec north
B) 48 kg-m/sec north
C) 3.0 kg-m/sec south
D) 48 kg-m/sec south

in simple terms, the principle states that the buoyancy force on an object is equal to the weight of the fluid displaced by the object, or the density of the fluid multiplied by the submerged volume times the gravitational acceleration, g. this is also known as upthrust.
