在第一小題裡面到了環的中心點是不是還具有重力位能-GMm/r？為什麼呢

R √3R m M 2. 有一均質固定圓環半徑為R,質量為M,在環的中心軸上, 距環心√3R 處有一質量為m的質點,(重力常數為G) (1)若質點原靜止,僅受環的重力作用,當質點到達環心處時 其速率為何?B)2:3 (2) 若欲使質點脫離環的重力作用範圍,則質點的初速率至少 為何? 答: 愛車

(41~43) At some stores, people get stickers or stamps on a card when they spend money there. After they collect enough stickers or stamps, they can get gifts or buy things at low prices. Yesterday after I bought coffee; the clerk stamped on my cellphone. How cool it was! My first time! It looks like a stamp we used in the past, but there are many small dots at the bottom. You touch the screen of your cellphone to tell it what to do, and this is also the way smart stamps work. When people use a smart stamp, they hold the top part of the smart stamp. The small electrical charge from people's hands goes through it to the dots at the bottom. Then, the smart stamp tells your cellphone messages with them. The dots of different stores are in different patterns. no alla lil est sill lo busolos With smart stamps, stores don't have to make stickers or cards, and people don't have to keep those things.
