Problem: Electric motor:

All the electromagnetic motors, and that includes the types mentioned here derive the torque from the vector product of the interacting fields. For calculating the torque it is necessary to know the fields in the air gap . Once these have been established by mathematical analysis using FEA or other tools the torque may be calculated as the integral of all the vectors of force multiplied by the radius of each vector. The current flowing in the winding is producing the fields and for a motor using a magnetic material the field is not linearly proportional to the current. This makes the calculation difficult but a computer can do the many calculations needed.

What is the formulia to determine torque?
---
A: the integral of all the vectors of force multiplied by the radius of each vector

Problem: The empire went into decline thereafter. The Mughals suffered several blows due to invasions from Marathas and Afghans. During the decline of the Mughal Empire, several smaller states rose to fill the power vacuum and themselves were contributing factors to the decline. In 1737, the Maratha general Bajirao of the Maratha Empire invaded and plundered Delhi. Under the general Amir Khan Umrao Al Udat, the Mughal Emperor sent 8,000 troops to drive away the 5,000 Maratha cavalry soldiers. Baji Rao, however, easily routed the novice Mughal general and the rest of the imperial Mughal army fled. In 1737, in the final defeat of Mughal Empire, the commander-in-chief of the Mughal Army, Nizam-ul-mulk, was routed at Bhopal by the Maratha army. This essentially brought an end to the Mughal Empire. In 1739, Nader Shah, emperor of Iran, defeated the Mughal army at the Battle of Karnal. After this victory, Nader captured and sacked Delhi, carrying away many treasures, including the Peacock Throne. The Mughal dynasty was reduced to puppet rulers by 1757. The remnants of the Mughal dynasty were finally defeated during the Indian Rebellion of 1857, also called the 1857 War of Independence, and the remains of the empire were formally taken over by the British while the Government of India Act 1858 let the British Crown assume direct control of India in the form of the new British Raj.
What groups invaded and damaged the Mughals?

Answer: Marathas and Afghans

Q: What is a question about this article? If the question is unanswerable, say "unanswerable".
By the early 18th century, the Maratha Kingdom had transformed itself into the Maratha Empire under the rule of the Peshwas (prime ministers). In 1737, the Marathas defeated a Mughal army in their capital, Delhi itself in Battle of Delhi (1737). The Marathas continued their military campaigns against Mughals, Nizam, Nawab of Bengal and Durrani Empire to further extend their boundaries. Gordon explained how the Maratha systematically took control over new regions. They would start with annual raids, followed by collecting ransom from villages and towns while the declining Mughal Empire retained nominal control and finally taking over the region. He explained it with the example of Malwa region. Marathas built an efficient system of public administration known for its attention to detail. It succeeded in raising revenue in districts that recovered from years of raids, up to levels previously enjoyed by the Mughals. For example, the cornerstone of the Maratha rule in Malwa rested on the 60 or so local tax collectors who advanced the Maratha ruler Peshwa a portion of their district revenues at interest. By 1760, the domain of the Marathas stretched across practically the entire subcontinent. The north-western expansion of the Marathas was stopped after the Third Battle of Panipat (1761). However, the Maratha authority in the north was re-established within a decade under Peshwa Madhavrao I. The defeat of Marathas by British in third Anglo-Maratha Wars brought end to the empire by 1820. The last peshwa, Baji Rao II, was defeated by the British in the Third Anglo-Maratha War. With the defeat of the Marathas, no native power represented any significant threat for the British afterwards.
By when had the Maratha kingdom become an empire?
A: early 18th century

Context and question: One of the most important developments that the Enlightenment era brought to the discipline of science was its popularization. An increasingly literate population seeking knowledge and education in both the arts and the sciences drove the expansion of print culture and the dissemination of scientific learning. The new literate population was due to a high rise in the availability of food. This enabled many people to rise out of poverty, and instead of paying more for food, they had money for education. Popularization was generally part of an overarching Enlightenment ideal that endeavoured "to make information available to the greatest number of people." As public interest in natural philosophy grew during the 18th century, public lecture courses and the publication of popular texts opened up new roads to money and fame for amateurs and scientists who remained on the periphery of universities and academies. More formal works included explanations of scientific theories for individuals lacking the educational background to comprehend the original scientific text. Sir Isaac Newton's celebrated Philosophiae Naturalis Principia Mathematica was published in Latin and remained inaccessible to readers without education in the classics until Enlightenment writers began to translate and analyze the text in the vernacular.
Which ideal endeavoured to make information available to the greatest number of people?
Answer: Popularization

Question: Rajasthan is[when?] earning Rs. 150 million (approx. US$2.5 million) per day as revenue from the crude oil sector. This earning is expected to reach 250 million per day in 2013 (which is an increase of 100 million or more than 66 percent). The government of India has given permission to extract 300,000 barrels of crude per day from Barmer region which is now 175,000 barrels per day. Once this limit is achieved Rajasthan will become a leader in Crude extraction in Country. Bombay High leads with a production of 250,000 barrels crude per day. Once the limit if 300,000 barrels per day is reached, the overall production of the country will increase by 15 percent. Cairn India is doing the work of exploration and extraction of crude oil in Rajasthan.
Is there an answer to this question: What amount is expected to be earned from oil in Cairn India in 2013?

Answer: unanswerable

During the late Bronze Age the island experienced two waves of Greek settlement. The first wave consisted of Mycenaean Greek traders who started visiting Cyprus around 1400 BC. A major wave of Greek settlement is believed to have taken place following the Bronze Age collapse of Mycenaean Greece from 1100 to 1050 BC, with the island's predominantly Greek character dating from this period. Cyprus occupies an important role in Greek mythology being the birthplace of Aphrodite and Adonis, and home to King Cinyras, Teucer and Pygmalion. Beginning in the 8th century BC Phoenician colonies were founded on the south coast of Cyprus, near present-day Larnaca and Salamis.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): Cyprus is home to which Greek mythological figures?
Ah, so..
King Cinyras, Teucer and Pygmalion
