2 cangkir yang masing2 berisi air bersuhu 60 drjt R dicampur dgn 1 cangkir 30 drjt C = ... C
Sdr. Handri. Pertanyaan anda coba saya bantu untuk menjawabnya.
Soal tersebut bisa diselesaikan. dengan anggapan bahwa "1 cangkir" mewakili 1 satuan massa. Dari soal tersebut suhu 2 cangkir adalah 60oR = 75oC. Sesuai asas Black :
Qdilepas = Qditerima
2m. cair. (ttinggi- tcampuran) = 1m. cair. (tcampuran- trendah)
2. (75 - tc) = 1. (tc - 30)
150 - 2 tc = tc - 30 diperoleh 3 tc = 180, maka tc = 60oC
Demikian, semoga membantu.

Prisma tegak ABCD.EFGH beralaskan persegi panjang dengan AB=18 cm dan BC=10 cm. Bila AE = 30 cm, berapa seluruh permukaan prisma ?
Prisma tegak ABCD.EFGH , alas berupa persegi panjang, AB = 18 cm, BC = 10 cm dan Tinggi ( AE = 30 cm ). Luas permukaan prisma adalah sbb;
Jadi luas Permukaan Prisma = 2040 cm2
Balok ABCD EFGH, diketahui perbandingan AB : BC : CG = 7 : 4 : 3. Apabila volumenya 2.268 cm3, erapa jumlah panjang seluruh rusuknya ?
Misalnya perbandingan AB : BC : CG = P : l : t = 7 : 4 : 3
Jadi Panjang rusuk AB = DC = EF = GH = 21 cm
Panjang rusuk BC = FG = AD = EH = 12 cm
Panjang rusuk AE = DH = BF = CG = 9 cm
Jadi jumlah panjang rusuk semuanya =
21 x 4 + 12 x 4 + 9 x 4 = 88 + 48 + 36 = 172 cm

tolong dong artikan ke bahasa indonesia
With all due respect to the honorable judges, to the teacher from all Senior High Schools in Bekasi, and all the audience here, ladies and gentlemen… Good Morning!!
First of all, let us thank Allah SWT because of his blessings, we all can gather here on this sunny morning. Shalawat and prayer, we will say to our greatest prophet Muhammad SAW, his family, his friends and his followers. Amen.
In this chance, I would like to tell you my speech that has the theme “Go Green!”
Saving Our Planet is a program that was persuading the earthlings so that they would become more concern and care to their entire environment. It was because the civilization that has been created by the modern people in this millennium era had affected so many destructive impacts which are really needed to be concerned. These impacts are causing a new problem, The “Global Warming”. In prediction, that in the last 100 years the temperatures of our planet has increased by 1’ every year. Meanwhile, the ocean surface has increased for about 1 meter from its former level. The problem is, modern people not only wanted to increase their prosperity, but also increase their rate of comfortable & luxurious life.
The situation was very different if we looked back to the last century where the pollution, the industrial garbage, and the toxin gases were friendlier. Friendlier, because on the 19th Century the technologies improvement and the consumerism character was not yet significant. Or should we say in this millennium era, the Earth exploitation and exploration were causing the crucial problem for the earthlings.
How crucial the earth environmental problems we face are for example: The protected animals & plants from certain species nearly extinct, the plantation sector is causing another problem for environment & ecosystem, forest logging without reboization, and the impact of mines exploitation that cannot be recycled and maintenance of mine sector, etc. For us, the youth generation is asking to the politicians and the government especially in Indonesia, “Why do those problems I mentioned left uncared without any preventive actions?” In fact, our ex-Minister of Environment of “Orde Baru” era Prof. Dr. Emil Salim has warned and gave us an opinion about will happen on the next 20 years. He said that the situation will be dangerous if there are no actions to prevent this. We need the proactive steps to maintain the nature and to rehabilitee what we have disrupted from every department that is connected with the environmental cases and our community. The example about the impact of human’s greed to the nature is The Lapindo Brantas case. That’s how the nature shows us their power. There’s not even one human could stand against the power of nature. Until now, there are no ways to stop the mud throwing and even the poisonous gases that is unwanted by the people.
We as the khalifah of the Earth can only begging, begging, and begging to the nature and destroy the nature. But when we must give something to the nature or maintain the nature, we feel that we don’t want to! Is the nature retaliating our doings? When we think deeply over this I guess the answer is “yes”, the nature is angry to us. The nature’s balance was really disturbed by the mortal’s hands and this behavior has spread widely over the world because of our hedonism.
The question is “How”? How do we realize collectively for the world’s life so that so that the Earth could become a better place to live…?
We as the youth generations, the lines of the civilization must be as one to create the vision & mission to help the government and the people for watching over the reboization program and for the environment reparation that is caused by the industrialist and the people generally wherever they are. We as the youth generation without exception must be totally devote our bodies & wills for the sake of healthy world, comfortable world, and for the sake of better place to live…
I suggest to the government and the people of Indonesia to plant the cambium plants or the pot plants on every one of the house garden. Everyone, every people must be responsible for every single of plants. Imagine! If every people have 1 plant in one house, there are 200 millions of plants in Indonesia. This is a very good step to begin our mission to prevent the Global Warming. Start this on any time now! For my recommendation, the sansivieras (one of the most beautiful pot plant) is really good to kept because of its great use of anti-pollutant & anti-free radical. Besides, its beauty will decorate our house so that we won’t feel bad to buy it.
Well, I guess that’s all I can tell. In the end, to show our devotion as the youngish, the lines to the future, we must be balanced it with faith and taqwa because those are our capitol to realize our wishes so that we can live in perfect harmony just as Allah SWT has confirmed to us.
Wassalamualaikum Wr Wb.
