(a) force of gravity (c) electrostatic force a) Calculate the absolute pressure at an ocean depth of 1150 m. Assume that the density of sea water is 1021 kg/m3 and that the air above exerts a pressure of 101.3 kPa. 10. Question 3. Answer: Question 1. The continuous physical force exerted on an object (or against an object) by something in contact with it, is called pressure. Question 6. kids.earth.nasa.gov/archive/air_pressure/ The force of air on the atmosphere ... How the atmosphere exerts pressure through air. The strength of force is expressed by its (b) gravitational force Answered Which of the following correctly explains how air exerts pressure on us? The movement of gasses between the air and the water stops when these two pressures are equal. But if the force applied in the direction opposite to the motion, then it decreases the speed of the object. 3. 14. (b) 9.8 N T/F Air Pressure Increases With Increasing Altitude? Which of the examples shows that air exerts pressure? (c) (b) Temperature has increased. (b) mass Name the force exerted on a ball of dough to make a flat chapati. (c) gravitational (a) Question 4.
