Diving To Great Depths
Conceptual Physics help please?
okay so i have a test tomrow and ive been absent to i know nothing of this.
can you please explain? thanks 
1. what is the relationship between liquid pressure and depth of a liquid? and between liquid pressure and density.
2. by how much does a water pressure on a submarine change when the submarine dives to double its previous depth?
3. so now if the submarine operated in fresh water, would the pressure it feels be greater or less at the same depth in salt water?
its fine if u even only answer one
thxx
2. Water pressure is directly dependent on depth. Double the depth, double the pressure.
3. Salt water is more dense than fresh water. So for a given depth, pressure is greater in salt water then in fresh water.
1. Pressure in a liquid is directly dependent on depth.
Pressure is also dependent on the force pushing on an area. The gravity force water exerts on a surface depends on the mass of the water, and the mass of the water depends on its density. The greater the density the greater the pressure.
