Question: Located in Southern Europe, Greece consists of a mountainous, peninsular mainland jutting out into the sea at the southern end of the Balkans, ending at the Peloponnese peninsula (separated from the mainland by the canal of the Isthmus of Corinth) and strategically located at the crossroads of Europe, Asia, and Africa. Due to its highly indented coastline and numerous islands, Greece has the 11th longest coastline in the world with 13,676 km (8,498 mi); its land boundary is 1,160 km (721 mi). The country lies approximately between latitudes 34 and 42 N, and longitudes 19 and 30 E, with the extreme points being:
Try to answer this question if possible: Where does Greece's coastline place in world rankings?
Answer: 11th longest
Question: It established a colony at Jamestown, Virginia, in 1607. Two years later, a flotilla of seven ships left England under the Company's Admiral, Sir George Somers, and the new Governor of Jamestown, Sir Thomas Gates, with several hundred settlers, food and supplies to relieve the colony of Jamestown. Somers had previous experience sailing with both Sir Francis Drake and Sir Walter Raleigh. The flotilla was broken up by a storm. As the flagship, the Sea Venture, was taking on water, Somers drove it onto Bermuda's reef and gained the shores safely with smaller boats all 150 passengers and a dog survived. (William Shakespeare's play The Tempest, in which the character Ariel refers to the "still-vex'd Bermoothes" (I.ii.229), is thought to have been inspired by William Strachey's account of this shipwreck.) They stayed 10 months, starting a new settlement and building two small ships to sail to Jamestown. The island was claimed for the English Crown, and the charter of the Virginia Company was later extended to include it.

Question: After India gained independence, the Nizam declared his intention to remain independent rather than become part of the Indian Union. The Hyderabad State Congress, with the support of the Indian National Congress and the Communist Party of India, began agitating against Nizam VII in 1948. On 17 September that year, the Indian Army took control of Hyderabad State after an invasion codenamed Operation Polo. With the defeat of his forces, Nizam VII capitulated to the Indian Union by signing an Instrument of Accession, which made him the Rajpramukh (Princely Governor) of the state until 31 October 1956. Between 1946 and 1951, the Communist Party of India fomented the Telangana uprising against the feudal lords of the Telangana region. The Constitution of India, which became effective on 26 January 1950, made Hyderabad State one of the part B states of India, with Hyderabad city continuing to be the capital. In his 1955 report Thoughts on Linguistic States, B. R. Ambedkar, then chairman of the Drafting Committee of the Indian Constitution, proposed designating the city of Hyderabad as the second capital of India because of its amenities and strategic central location. Since 1956, the Rashtrapati Nilayam in Hyderabad has been the second official residence and business office of the President of India; the President stays once a year in winter and conducts official business particularly relating to Southern India.

Answer: 1948. On 17 September
Question: In September 2003, a new type of blue LED was demonstrated by Cree that consumes 24 mW at 20 milliamperes (mA). This produced a commercially packaged white light giving 65 lm/W at 20 mA, becoming the brightest white LED commercially available at the time, and more than four times as efficient as standard incandescents. In 2006, they demonstrated a prototype with a record white LED luminous efficacy of 131 lm/W at 20 mA. Nichia Corporation has developed a white LED with luminous efficacy of 150 lm/W at a forward current of 20 mA. Cree's XLamp XM-L LEDs, commercially available in 2011, produce 100 lm/W at their full power of 10 W, and up to 160 lm/W at around 2 W input power. In 2012, Cree announced a white LED giving 254 lm/W, and 303 lm/W in March 2014. Practical general lighting needs high-power LEDs, of one watt or more. Typical operating currents for such devices begin at 350 mA.

Answer:
Cree
