You are sharing a house with a few roommates. one of them plays on the basketball team, and is exactly 200 cm tall. the heights of you and the other roommates are 188 cm, 175 cm, and 160 cm. you want to buy the minimum height mirror that will allow all of you to see your entire selves, when the mirror is mounted in a fixed position on the wall. assume each person's eyes are at a level 95% of their height. how many centimeters above the floor should the top of the mirror be?

Two thin 80.0- cm rods are oriented at right angles to each other. each rod has one end at the origin of the coordinates, and one of them extends along the x- axis while the other extends along the yaxis. the rod along the x- axis carries a charge of - 15.0 μ c distributed uniformly along its length, and the other rod carries 15.0 μ c uniformly over its length. find the magnitude and direction of the net electrical force that these two rods exert on an electron located at the point (40.0 cm, 40.0 cm).
