You approach the door of your friends house. What is the first thing you do before entering? Of course, you wipe your feet. You are a thoughtful visitor. Fortunately, there is a nice piece of carpet by the door to wipe your shoes. Too bad your caring comes at a price. After wiping your feet on the mat you reach out to touch the brass knocker on the door. A spark suddenly jumps between your hand and the metal. You feel an electric shock. Why do you think an electric shock occurs? An electric shock occurs when there is a sudden discharge of static electricity. Has this ever happened to you? You reached out to touch a metal doorknob and received an unpleasant electric shock? The reason you get a shock is because of moving electric charges. Moving electric charges also create lightning bolts. It is also the same reason electric current flows through cables and wires.

You get shocked because of moving electric charges and moving electric charges also creates what?

The Dutch Take Over: Intent on capturing a piece of the Portuguese trade in pepper and other spices, the Java-based Dutch Ailied with the Malays in 1633 to blockade Melaka. The trade blockade was to last eight years, and ended in a seven-month siege. The Portuguese surrendered in 1641, wracked by malaria and dysentery and denied their usual reinforcements from Goa. By then, the city had become a stagnant backwater. Unlike the Portuguese, the Dutch decided to do business with the Malays of Johor, who controlled the southern half of the peninsula together with Singapore and the neighboring Riau islands. A trade treaty gave the Dutch command of the spice trade but reserved Johor's rights in tin exports from Perak, Selangor, and Klang. Without ever retrieving the supremacy of the old Melaka sultanate, Johor had become the strongest Asian power in the region. For the Dutch, Johor provided a buffer against other Europeans. Meanwhile, fresh blood came in with the migration into the southern interior of hardy Minangkabau farmers from Sumatra, while tough Bugis warriors from the east Indonesian Celebes (Sulawesi) roved the length and breadth of the peninsula. The Minangkabau custom of freely electing their leaders provided the model for rulership elections in modern federal Malaysia. Their confederation of States became today's Negeri Sembilan ("Nine States"), with Seremban as its capital. The name Minangkabau itself means roughly "buffalo horns" and is reflected in the distinctive upward curving roof in museums and government offices built in the traditional Minangkabau style. The Bugis were energetic merchants and great sailors. With the Dutch concentrating once more on Java and the Moluccas in the 18th century, the Bugis took advantage of the vacuum by raiding Perak and Kedah, imposing their chieftains in Selangor and becoming the power behind the throne in Johor. The Bugis in Johor's administration provided much of the spirit in that State's independent stand in the 19th and 20th centuries. Throughout this period, the east coast states enjoyed a relatively tranquil prosperity, Terengganu notably thriving from its textile industry and trading in pepper and gold with the Thais, Cambodians, and Chinese. The British, under the private auspices of the East India Company (EIC), were beginning to poke their noses into North Borneo.

Who's confederation of States became today's Negeri Sembilan?

When American 11 struck the World Trade Center at 8:46, no one in the White House or traveling with the President knew that it had been hijacked. While that information circulated within the FAA, we found no evidence that the hijacking was reported to any other agency in Washington before 8:46. Most federal agencies learned about the crash in New York from CNN. Within the FAA, the administrator, Jane Garvey, and her acting deputy, Monte Belger, had not been told of a confirmed hijacking before they learned from television that a plane had crashed. Others in the agency were aware of it, as we explained earlier in this chapter. Inside the National Military Command Center, the deputy director of operations and his assistant began notifying senior Pentagon officials of the incident. At about 9:00, the senior NMCC operations officer reached out to the FAA operations center for information. Although the NMCC was advised of the hijacking of American 11, the scrambling of jets was not discussed. In Sarasota, Florida, the presidential motorcade was arriving at the Emma E. Booker Elementary School, where President Bush was to read to a class and talk about education. White House Chief of Staff Andrew Card told us he was standing with the President outside the classroom when Senior Advisor to the President Karl Rove first informed them that a small, twin-engine plane had crashed into the World Trade Center. The President's reaction was that the incident must have been caused by pilot error. At 8:55, before entering the classroom, the President spoke to National Security Advisor Condoleezza Rice, who was at the White House. She recalled first telling the President it was a twin-engine aircraft-and then a commercial aircraft-that had struck the World Trade Center, adding "that's all we know right now, Mr. President." At the White House, Vice President Dick Cheney had just sat down for a meeting when his assistant told him to turn on his television because a plane had struck the NorthTower of the World Trade Center. The Vice President was wondering "How the hell could a plane hit the World Trade Center" when he saw the second aircraft strike the South Tower. Elsewhere in the White House, a series of 9:00 meetings was about to begin. In the absence of information that the crash was anything other than an accident, the White House staff monitored the news as they went ahead with their regular schedules.
What airplane crash did most federal agencies learn about through CNN, rather than their own internal reporting channels?
