Concept:Pascal's principle says an increase in pressure applied to a confined fluid spreads uniformly without loss throughout the fluid.Explanation:When external force presses on a confined liquid or gas, the particles transmit that force sideways, upward, and downward.Therefore, the resulting pressure acts the same at every point inside the fluid.As a result, this pressure is felt equally on all parts of the fluid and on the container walls.Answer:C. transmitted equally in all directions.
