4. A simple accelerometer can be made froma U-tube containing water as in 200mm Figure. 1) When the acceleration of a car with the U-tube is a [m/s?] in the horizontal direction (x-direction), find the relation between a and the level difference h [m]. 2) When H vertical tubes at a = 0 is 250 mm, find the maximum accelaration which h = 400 mm and the water level ho for both H h。 can be measured by this accelarometer. Use g = 9.8 m/s? and pwater = 1000 kg/m?. y water x

KEY VOCABULARY SKILLS STUDY SHEET 7, PAGE 164 The Duke of Edinburgh’'s Award The Duke of Edinburgh's Award (known as the DofE) began in the U.K. in 1956. It gives young people from all backgrounds an opportunity to experience challenge and adventure, acquire new skills, and make new friends. Each year, participants between the ages of 14 and 24 complete many hours of voluntary community work. There are three levels: Bronze, Silver, and Gold. Each one requires increasing commitment, so you can choose which level is best for you. There are four sections at Bronze and Silver level, and five at Gold. These sections combine practical, cultural, and adventurous activities. Achieving a Duke of Edinburgh's Award helps young people to develop a sense of responsibility, and promotes values of persistence, commitment, and enterprise. It has a lasting impact on young people's behavior, skils, and life chances. In 1988, the DofE was expanded to become international. These days, over 635,000 participants around the world are achieving a DofE at any one time. Since the DofE began, Over six million young people in over 123 countries have taken part, and it continues to grow in popularity. 1 an appointment / small talk / progress success / your goals / independence dark / older / crops 2 4 a course / a form / an exercise someone a chance / a talk / feedback 5 awareness / growth / competition a qualification / knowledge / a reputation for something a problem / dificulty / something at first hand a friendship / a taste for something / an idea 6 7 8 9 Predicting Look at the title of the information sheet you’re going to read.

この問題の⑵で、sの範囲で場合分けをするは分かるのですが、接線の傾きを求める時にたとえば原点もx＝3/2も片方の放物線を使ってるけれど、なんでx/4では出来ないんだろうって思って教えて欲しいです。 x/4だったら微分して4/1になっちゃうからx座標を代入できず傾きが求められ... Read More

解説で❔のところがいまいちわからなかったのですが、3で割った時、、、というのはnの数字から判断してるのでしよね？なんかa 4とかa 5とか調べないでなんでわかるのだろうって思っちゃったんですけどa1、2、3だけで判断できるんですか？？
