A kitchen sponge and a lead brick of equal size and shape sit on a wooden table. Units (cid:1) (cid:2) (cid:5)(cid:6) (cid:7)(cid:8) (cid:1)(cid:9)(cid:10)(cid:11) (cid:2) (cid:12)(cid:13)(cid:13)(cid:13) (cid:1)(cid:17)(cid:18)(cid:19)(cid:19)(cid:20) (cid:2) (cid:12)(cid:13)(cid:21)(cid:13) (cid:1)(cid:22)(cid:17) (cid:2) (cid:12)(cid:12)(cid:23)(cid:24)(cid:13)(cid:13) (cid:1)(cid:25)(cid:26)(cid:27) (cid:2) (cid:12)(cid:28)(cid:29)(cid:30) (cid:14)(cid:15) (cid:16)(cid:8) (cid:14)(cid:15) (cid:16)(cid:8) (cid:14)(cid:15) (cid:16)(cid:8) (cid:14)(cid:15) (cid:16)(cid:8) Suppose you push both a nail and a piece of chalk into your hand, applying the same force each time. Area of nail tip is much smaller than area of tip of chalk. Units: pressure is not a vector. (cid:2) (cid:7)& (cid:2) "( : high-heeled shoes can cause tremendous pressure to be applied to the floor. Suppose a 50. 0 kg woman is wearing shoes whose heels are circular with a radius of. + (cid:2) (cid:21)(cid:28)(cid:13)(cid:13) , (cid:12)(cid:13)-(cid:8) m. suppose that the woman is simply standing in place, resting her weight on her heels. What pressure is applied to the floor beneath each of the heels? (cid:31) (cid:2) Suppose you go swimming in a pool with either goggles on.
