1) Suppose you weigh 874N, and when you stand on one foot, your weight is spread out over an area of 1.590×10-2m2. What is the pressure does your foot exert on the floor? (Check out the book or online for the correct unit. Remember that there is also a blue help button if the units are inconsistent.)
2) Atmospheric pressure is around 1.010×105 Pa. Think about the air pushing on a flat, circular glass window which has a radius of 0.0830m. What is the force with which the air is pushing on one side of the glass?
