You are assigned the design of a cylindrical, pressurized water tank for a future colony on mars, where the acceleration due to gravity is 3.71 m/s2. the pressure at the surface of the water will be 110 kpa , and the depth of the water will be 13.6 m . the pressure of the air outside the tank, which is elevated above the ground, will be 93.0 kpa .

Convection currents are caused by differences in what two things?

Gravity is pulling an object into the sun. the closer the object gets to the sun, the greater the gravitational force that acts on the object, increasing its acceleration. a line graph plotting the speed of the object against time would have which shape? a: straight line of positive slope b: curved line that slopes upward c: curved line that slopes downward d: straight line of negative slope

Why is the basic problem of economic, scarcity, a universal problem?
