Answer:
The water pressure at the bottom of the jar will increase by 1000 Pa.
Step-by-step explanation:
Water is almost incompressible this means that the volume of the fluid does not change with the application of pressure. This means that if pressure is applied it will be equally distributed in the liquid.
Here, if the jar of water which is filled and sealed is pushed on the lid the pressure at the bottom of the jar will be increased by 1000 Pa.
