You are standing on a street corner with your friend. You then travel 14.0 mm due west across the street and into your apartment building. You travel in the elevator 22.0 mm upward to your floor, walk 12.0 mm north to the door of your apartment, and then walk 6.0 mm due east to your balcony that overlooks the street. Your friend is standing where you left her. Now how far are you from your friend?
Express your answer with the appropriate units.

When a charged balloon sticks to a wall, the downward gravitational force is balanced by an upward static friction force. the normal force is provided by the electrical attraction between the charged balloon and the equal but oppositely charged polarization induced in the wall's molecules. if the mass of a balloon is 1.2 g, its coefficient of static friction with the wall is 0.71, and the average distance between the opposite charges is 0.80 mm, what minimum amount of charge must be placed on the balloon in order for it to stick to the wall? express your answer to two significant figures and include appropriate units.
