Bridges What kinds of bridges are there? 行走 1 Have you ever stepped on a stone to get across a puddle or stream? If you have, you were using a bridge. 橋 不同尺寸 Bridges are different sizes and shapes. Some bridges have straight "legs or supports, called beams. Other bridges have curved supports, called 拱橋 arches. Still others actually 45 - Lit 堅強 鋼索 hang from strong steel ropes, 上弦 or cables, that are strung 上面 表面 above the surface of the bridge. The cables are the attached to the land on either end of the bridge. 3 Most bridges go over water, but some bridges were made to TEA JI carry water. About 2,000 years ago, the Romans built this kind of bridge. One such bridge, in 347. France, had three levels. Water flowed in the top level, and 人国 70 people and carts traveled on the two lower levels.

are one billion nanometers in one meter, you can get an idea of how impressive this technology really is! Even though this fabulous technology has been around for almost 100 years, we have only recently been able to experience both its benefits and i cogmignal ovil Asqa niso I e maoney but also area Stopesugar have characteristics These days, nanotechnology is used primarily to make things stronger, stiffer, and smoother. Due to their tiny size, nanoparticles increase the overall surface a of an object, and that acts to give the object special properties However, nanotechnology is also used in the field of biochemistry. One possible of nanotechnology in the future is in the field of robotics. It might be feasible for tiny nano-robots, or "nanobots," to be produced that could easily perform tasks in a very small scale. Each of these nanobots would be so small that you would need a special microscope to see them.

Because of their size, they can float around in the air and enter our lungs without our knowing about it. The effects of this are not yet known, but in the future, if the use of this sort of technology becomes more common, some specialists believe that we may suffer from various illnesses.

想請問這題🙏，有點看不懂圖三的公式是從何而來，卡住了

EXAMPLE 21.11 FIELD OF A UNIFORMLY CHARGED DISK A nonconducting disk of radius R has a uniform positive surface charge density o. Find the electric field at a point along the axis of the disk a distance x from its center. Assume that x is positive. SOLUTION IDENTIFY and SET UP: Figure 21.25 shows the situation. We rep- resent the charge distribution as a collection of concentric rings of charge dQ. In Example 21.9 we obtained Eq. (21.8) for the field on the axis of a single uniformly charged ring, so all we need do here is integrate the contributions of our rings. EXECUTE: A typical ring has charge dQ, inner radius r, and outer radius r + dr. Its area is approximately equal to its width dr times its circumference 2πr, or dA = 2πr dr. The charge per unit area is σ = dQ/dA, so the charge of the ring is do = o da = 2πor dr. We use dQ in place of Q in Eq. (21.8), the expression for the field due to a ring that we found in Example 21.9, and replace the ring 21.25 Our sketch for this problem. Idr dQ X P dEx dEx radius a with r. Then the field component dEx at point P due to this ring is 1 2πσrx dr 4π€0 (x² + ²)3/2 SOLUTION Continued
