The water level in a tank is 34 ft above the ground. a hose is connected to the bottom of the tank at the ground level and the nozzle at the end of the hose is pointed straight up. the tank cover is airtight, but the pressure over the water surface is unknown. determine the minimum tank air pressure (gage) that will cause a water stream from the nozzle to rise 72 ft from the ground.

Ihave a density of 1.61g/cm^3 and a mass of 28g. find the missing value

Specific heat refers to the amount of heat required to change 1 gram of a substance by degree(s) celsius

Place several e-field sensors at a few points on different equipotential lines, and look at the relationship between the electric field and the equipotential lines. which statement is true? 1-at any point, the electric field is perpendicular to the equipotential line at that point, and it is directed toward lines of higher voltages. 2-at any point, the electric field is perpendicular to the equipotential line at that point, and it is directed toward lines of lower voltages. 3-at any point, the electric field is parallel to the equipotential line at that point.
