Ex Input:
Oscar-winning actress Joan Fontaine died Sunday, her longtime friend Noel Beutel said Monday. She was 96. Fontaine died "very peacefully" in her sleep of natural causes, Beutel said. She was in her Carmel, California, home. She is survived by her older sister, actress Olivia de Havilland -- with whom she had not spoken for decades. Fontaine was born Joan de Beauvoir de Havilland in 1916 in Tokyo, Japan, where her British father was a patent lawyer and teacher. She and her sister moved to Saratoga, California, with their mother in 1919 when her parents separated. Fontaine was a teenager when she began her acting career as Joan Burfield in the 1935 film "No More Ladies." She later adopted the stage name Fontaine -- the name of her mother's second husband. She wrote in her 1978 autobiography, "No Bed of Roses," that her mother, who was an actress, began encouraging the rivalry with her older sister at an early age. The feud extended to their careers when both sisters were nominated for best actress Oscars in 1942. Fontaine, who was nominated for Alfred Hitchcock's "Suspicion," beat her sister Olivia de Havilland, who was nominated for "Hold Back the Dawn." De Havilland won the first of her two Oscars in 1947 when she was given the best actress award for "To Each His Own." De Havilland and Fontaine remain the only sisters who have best-actress Academy Awards. The long-standing feud with de Havilland was at such a peak during one Oscar winners' reunion in 1979 that they had to be seated on opposite ends of the stage. "I was shocked and saddened to learn of the passing of my sister, Joan Fontaine ... and I appreciate the many kind expressions of sympathy that we have received," a statement released by Olivia de Havilland to CNN said. <sep>How many years did it take for her to get the Oscar after she was nominated for the first time?<sep>None

The Glory of Melaka: In the early days, if you were not a pirate or a mosquito, Melaka was not much of a place to live. The land was infertile, just a swampy plain, the river small and sluggish. But it had a sheltered harbor, protected from the monsoons by neighboring Sumatra. Later, the strategic location and deep-water channel close to the coast brought in the bigger vessels of the trade-wind traffic crossing the Indian Ocean. The first to realize the larger commercial potential, as so often throughout the country's subsequent history, were the Chinese. In 1409, under a new directive from Emperor Chu Ti to pursue trade in the South Seas and the Indian Ocean, a Chinese fleet of 50 ships headed by Admiral Cheng Ho called in at Melaka. They made Parameswara an offer he could not refuse: port facilities and an annual financial tribute in exchange for Chinese protection against the marauding Thais. In 1411, Parameswara took the money to Beijing himself, and the emperor gratefully made him a vassal king. Twenty years later, the Chinese withdrew again from the South Seas trade. The new ruler of Melaka, Sri Maharajah, switched his allegiance to the Muslim trading fraternity by marrying into the Muslim faith, wedding the daughter of a sultan in Sumatra. Islam won its place in Malaya not by conquest — as had been the case in North Africa and Europe — but by trade, dynastic alliances, and peaceful preaching. Bengali peddlers had already brought the faith to the east coast. In Melaka and throughout the peninsula, Islam thrived as a strong, male-dominated religion of individuality, offering dynamic leadership and preaching brotherhood and self-reliance — all qualities ideally suited to the coastal trade. At the same time, Sufi mystics synthesized Islamic teaching with local Malay traditions of animistic magic and charisma, though Islam did not become the state religion until Muzaffar Shah became sultan of Melaka (1446–1459). But the key figure in the sultanate was Tun Perak, bendahara (prime minister) and military commander. He expanded Melaka's power along the west coast and down to Singapore and the neighboring Bintan islands. He also had orang laut pirates patrolling the seas to extort tribute from passing ships. After Ailied district chiefs had repelled assaults from Thai-controlled armies from Pahang, Tun Perak personally led a famous victory over a Thai fleet off Batu Pahat in 1456. <sep>Describe the land of Melaka<sep>It was infertile, just a swampy plain, the river small and sluggish

Gravitational Potential Energy is affected by position. Like the leaves on trees, anything that is raised up has the potential to fall. It has potential energy. You can see examples of people with gravitational potential energy in 1.5 Figure below. Gravitational potential energy depends on two things. It depends on its weight, because a large falling rock can do more damage than a leaf falling from a tree. It also depends on its height above the ground. Like the skateboarder, the higher the ramp, the faster he will be going when he reaches the bottom. Like all energy, gravitational potential energy has the ability to do work. In this case, weight has the potential to deliver a force. More important for us is that it has the ability to cause change. What kind of change you may ask? Gravitational potential energy has the ability to cause motion. <sep>What are two things that Gravitational Potential Energy dependent on?<sep>Weight and height above ground
