What is the pressure at the bottom of a tank 1 m deep? Take the density of water to be 1000 kg/m^3, and gravitational acceleration to be 9.8 m/s^2. Enter your answer in N/m^2. What would the pressure at the bottom of the tank in the previous question be if it were in an elevator accelerating upward at 2 m/s^2?

the earths atmosphere is made up of nitrogen and oxygen. solids can turn into gasses through a process called sublimation. sublimation is the transition of a substance directly from the solid to the gas phase, without passing through the intermediate liquid phase.
