Lempengan-lempengan batu tersebut tidak bisa meluncur lancar. Sementara itu, lempengan batu tersebut masih mendorong satu sama lain.Setelah beberapa waktu, lempengan batu tersebut patah karena semua tekanan yang terjadi. Ketika lempengan batu tersebut patah, gempa bumi pun terjadi.
A kite is an object which is made from a light material stretched over a frame. Due to its light material a kite will lift off the ground and fly when it is tilted into the wind.To fly, a kite is uses wind to make it fly because it is heavier than air. When wind travels over the surface of the kite, it is split into two streams of air. One stream of the air goes over the kite while the second stream goes under the kite. The upper stream creates an area of low pressure above the kite. The lower stream hits the kite at a shallow angle and creates anarea of high pressure. The high pressure area has a pushing effect while the low pressurearea has a pulling effect.The combination of push and pull can creates enough force to lift the kite into the air.
Terjemahan:
Layang-layang adalah sebuah benda yang terbuat dari bahan ringan yang membentang diatas sebuah bingkai. Karena ringanya bahan, layang-layang akan terangkat dari tanah danterbang ketika dihadapkan dengan angin.Layang-layang menggunakan angin untuk membuatnya terbang. Ketika angin bergerak diatas permukaan layang-layang, angin tersebut terbagi menjadi dua aliran udara. Satu aliranudara bergerak di atas layang-layang sementara aliran kedua bergerak di bawah layang-layang. Aliran angin yang bergerak ke atas membuat sebuah area di layang-layang dengan tekanan rendah. Aliran udara yang bergerak ke bawah membentur layang-layang di sudut permukaan dan menciptakan daerah dengan tekanan tinggi. Daerah tekanan tinggi memiliki efek mendorong sementara daerah tekanan tekanan rendah memiliki efek menarik.Kombinasi efek dorongan dan tarikan tersebut dapat menciptakan kekuatan yang cukup untuk mengangkat layang-layang ke udara.
How a cell phone works
A cell phone is a great gadget in this modern world. What is a cell phone? A cell phone is actually a radio in certain way. Like a radio, by a cell phone we can communicate to other people in real time. Million people use cell phones for their communication. Even nowadays, people use cell phones to communicate in voice, written and data.
A cell phone or in long term “cellular telephone’ works by transmitting signals of radio to towers of cellular. The towers are networked to a central switching station. The connection usually uses wire, fiber optic-cables, or microwave.Then the central switching station which handles calls in certain given area is directed connected to the wire-based telephone system. Cellulars are pick up by the towers and relayed to another cellular telephone user or the user of wire-based telephone network. The towers vary in the capacity and capability to receive signals. Some can receive the signal from a short distance and the others can receive more distance. However, there are usually more than one tower in certain given area so that the system can handle the increasing telephone traffic.
