What happens to the pressure in all parts of a confined fluid if the pressure in one part is increased? What happens to the pressure in all parts of a confined fluid if the pressure in one part is increased? The pressure in the other parts remains the same. The pressure everywhere increases by different amounts depending on the area of each part. The pressure everywhere increases by the same amount. The pressure everywhere decreases to conserve total pressure.
What happens to centripetal force when speed decreases, in the special case that the object continues moving in a circle of the same radius? a)The force increases. b)The force sometimes stays the same and sometimes decreases. c)The force also decreases. d)The radius cannot stay the same.Speed does not affect centripetal force.
apply upward pressure to the diaphragm. this represents how the diaphragm looks when relaxed. what has happened to the pressure of the system ( has it increased or decreased) what happened to the volume of the lungs
