at a given depth a liquid exerts more pressure if in downward direction or upward direction
Answers
Explanation:
Downward direction because of gravity
Answer:Pressure acts in all directions in fluids.
Fluids are made of a large number of very small particles, much too small to see. These particles are in constant, rapid motion. They bump into one another. They bump into the walls of any container that holds them. They bump into objects in the fluid.
As the particles of a fluid bump into an object in the fluid, they
apply forces to the object. The forces, acting over the object’s surface, exert pressure on the object.When the pressure in a fluid increases, the particles bump together more frequently. This increases the pressure on objects in the fluid.
The pressure a fluid exerts on an object in the fluid is applied in
all directions. That is because the particles that make up the fluid can move in any direction. These particles exert forces as they bump into objects in the fluid. The picture shows how water exerts pressure on a diver who is underwater. Notice that the arrows point in different directions. That is because the water is pressing all around the diver, not just from above. check your reading
How does understanding particle motion help you to understand pressure?
Pressure in Fluids
Randomly moving water molecules collide with a diver. The net force from the many collisions produces the pressure on the diver.
