(2)iiの位相の問題について、先生が出している解答は0.50π radなのですが、どうやっても答えがπ radにしかなりません。(iの答えは、周期3.0s、波長6.0m、速さ2.0m/sです)どっちが合っているか教えていただきたいです😭よろしくお願いします。

| 次の各文章を読み, あとの問いに答えなさい。 Iの波は,波面の形を保ったまま進行する。 波面上の各点からは(ア)が出て新たな波をつく り,これが次の波面を形成する。これを(イ)の原理という。この考え方を用いると,波が障害 物の陰の部分にまで回り込む(ウ)や,異なる媒質に入射して進行方向を変える(ェ) の説明ができる。 2つ以上の波が重ね合わさると(オ)が生じ、強め合いや弱め合いが見られる。ここで重 要なのは(カ)であり,特に波が反射する場合, 固定端で反射した場合は(カ)は(キ) ずれる。 Ⅱ 光波のうち、人間が視認できる光を(ク)という。 波長によって速さが異なるため, 白色光を プリズムに通すと, (ケ)が起こり,(コ)が得られる。 太陽光の連続 (サ) の中には多くの 暗線が見られ,これを(サ)線という(図1)。 光は媒質中の微粒子によって四方に散らされる ことがあり,これを(シ)という。特に波長の短い光ほど強く散らされるため, 空が青く見える現 象や, 夕方に太陽が赤く見える現象が説明できる。 このように、 光の波長による (シ) の違いは自 然現象の色彩に大きな影響を与えている。 また, 光の振動方向が特定の向きにそろえられた状態 を(ス)という。 7.06.5 6.0 5.5 5.0 4.5 4.0 波長 (×10-7 m) 図1 (1) 各文章 I, II の空欄(ア)~(ス)に当てはまる語句や数を入れなさい。 (2) 下線部①について,ある正弦波がx軸の正の向きに進んでおり,時刻t [s]における位置x [m]で の変位y [m]は, y = 0.40 sin 2 ( 32.0-20)と表される。これについて,次の問いに答えなさい。 = = Mof1 ± 4.2.0 60 ・20 i 波の周期, 波長, 速さをそれぞれ求めなさい。 ii 位置x =3.0mにおける位相は,x=0m に比べて何rad 遅れているか。 円周率を用いて表 0.40smz (12) 0.40m Tirad しなさい。 この正弦波がx軸の負の向きに進む場合,位置x [m]での媒質の変位y [m]と時刻t [s]の関 係を表す式を求めなさい。 2TV 12. 30 TV tos2(オープン) 2

But you 2-53 couldn't have known how much Facebook can learn about you from the smallest of social interactions - a 'like'*. (1) Researchers from the University of Cambridge designed (2) a simple machine-learning 2-54 system to predict Facebook users' personal information based solely on which pages they had liked. E "We were completely surprised by the accuracy of the predictions," says Michael 2-55 Kosinski, lead researcher of the project. Kosinski and colleagues built the system by scanning likes for a sample of 58,000 volunteers, and matching them up with other 10 profile details such as age, gender, and relationship status. They also matched up those likes with the results of personality and intelligence tests the volunteers had taken. The team then used their model to make predictions about other volunteers, based solely on their likes. The system can distinguish between the profiles of black and white Facebook users, 15 getting it right 95 percent of the time. It was also 90 percent accurate in separating males and females, Democrats and Republicans. Personality traits like openness and intelligence were also estimated based on likes, and were as accurate in some areas as a standard personality test designed for the task. Mixing what a user likes with many kinds of other data from their real-life activities could improve these predictions even more. 20 Voting records, utility bills and marriage records are already being added to Facebook's database, where they are easier to analyze. Facebook recently partnered with offline data companies, which all collect this kind of information. This move will allow even deeper insights into the behavior of the web users. 25 30 (3) - Sarah Downey, a lawyer and analyst with a privacy technology company, foresees insurers using the information gained by Facebook to help them identify risky customers, and perhaps charge them with higher fees. But there are potential benefits for users, too. Kosinski suggests that Facebook could end up as an online locker for your personal information, releasing your profiles at your command to help you with career planning. Downey says the research is the first solid example of the kinds of insights that can be made through Facebook. "This study is a great example of how the little things you do online show so much about you,” she says. "You might not remember liking things, " but Facebook remembers and (4) it all adds up.", * a 'like': フェイスブック上で個人の好みを表示する機能。 日本語版のフェイスブックでは「いいね!」 と表記される。 2-56 2-57 2-58 36
