1.) Suppose you weigh 587 N, and when you stand on one foot, your weight is spread out over an area of 1.510×10-2 m2. What is the pressure does your foot exert on the floor?
2.) Atmospheric pressure is around 1.010×105 Pa. Think about the air pushing on a circular glass window which has a radius of 0.0810 m. What is the force with which the air is pushing on one side of the glass?
