Mia walks with a velocity of 1.3 m/s south. she does so while riding on a train that is traveling with a velocity of 4.6 m/s north. what is mia`s velocity?

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.

mass and volume are the answers you are looking for
