A Unit 1 8 Environment The Melting Ice Caps The world's ice is melting, and it is happening at an alarming speed, rate, 3 Global warming has been increasing at a very unsustainable² and the polar ice caps have been vanishing³ before our eyes. In the 55 years between 1961 and 2016, the Earth's total ice loss amounted to an estimated nine trillion³ tons. The start of the 21st century bore witness to several profound decreases in terms of the area covered annually by Arctic ice. The year 2012 was the lowest on record, while 2007, 2016, and 2019 were tied for second-lowest. 10 As the ice melts, an excessive amount of melted water emerges from it. This large amount of melted water manifests itself as a rise in sea levels. (This rise leads to the increased erosion -or wearing away- of the coast. When combined with the higher frequency of ecological" disasters¹2, it results in a bigger storm surge¹3. Climate change threatens¹4 15 to forever change the way we live. We're all destined ¹5 to be affected by it. Ver all destined 閱讀理解,請在下列選項中,選出最適合的答案。 1 What does the word "erosion" refer to in the second paragraph?

求解謝謝拜偷了😭😭🙏🏿🥹 有算了一次 不確定對不對

,正我 15. 高速公路從交流道4到交流道B這個長8公里的路段上(以下簡稱 A-B 路段) 該路段總長度 該路段行駛總時間 該路段的車輛總數 該路段總長度 假設每日上午8時到9時 4-B 路段的,與d均保持不變,數學家建立了一個 v 與 d的數學模型: v=車輛平均行駛速度= E d=車輛密度= k-v log d=- 65 其中k為常數。已知 10 月1 日上午8時該路段車輛平均行駛速度v=88,且此時 車輛密度d=10。請根據這個模型,回答下列問題。 (1)常數k 的值為下列哪一個選項?(單選) | = k-88 k = 65 65 +88 (A) 23 (B) 65 (C) 76 153 (單位:臺/公里) (單位:公里/小時), (3) 小明在10月9日上午8時從交流道4開車行駛到交流道B花費6分鐘,而在 10 月 10 日上午8 時從交流道4開車行駛到交流道B花費 12 分鐘。請問 10月 10日上午8 時 4-B 路段的車輛密度,是該路段在10月9日上午8時的車輛密 |108.臺南女中| 度之多少倍?(四捨五入至整數,計算) 10 日 80 80 = 旧8x40:40 (D) 88 (2)已知在10月5日上午8時43路段的車輛總數為184臺,則此時該路段車輛,4 的平均行駛速度為每小時 公里。(四捨五入至整數,填充) (E) 153 = 23 8 (0923-1531 65 6510923=153 logd = 153-80 65 d=153-40 log de tot 10g 數學(1) =1.12²~ 10¹ ¹3³ = 10 =1-13~ 0.61 列選項 10000 切後 定 就 4倍
