QUES: Jehovah's Witnesses believe that God's kingdom is a literal government in heaven, ruled by Jesus Christ and 144,000 "spirit-anointed" Christians drawn from the earth, which they associate with Jesus' reference to a "new covenant". The kingdom is viewed as the means by which God will accomplish his original purpose for the earth, transforming it into a paradise without sickness or death. It is said to have been the focal point of Jesus' ministry on earth. They believe the kingdom was established in heaven in 1914, and that Jehovah's Witnesses serve as representatives of the kingdom on earth.
How many Jehovah's Witnesses are there now?

ANS: unanswerable

QUES: No satisfactory explanation can as yet be given for the exact mechanisms determining the formation of earlywood and latewood. Several factors may be involved. In conifers, at least, rate of growth alone does not determine the proportion of the two portions of the ring, for in some cases the wood of slow growth is very hard and heavy, while in others the opposite is true. The quality of the site where the tree grows undoubtedly affects the character of the wood formed, though it is not possible to formulate a rule governing it. In general, however, it may be said that where strength or ease of working is essential, woods of moderate to slow growth should be chosen.
While there is some relationship between where and how a tree grows, what can't anyone formulate to govern it?

ANS: a rule

QUES: During the Middle Ages Aristotle's theory of tabula rasa was developed by Islamic philosophers starting with Al Farabi, developing into an elaborate theory by Avicenna and demonstrated as a thought experiment by Ibn Tufail. For Avicenna (Ibn Sina), for example, the tabula rasa is a pure potentiality that is actualized through education, and knowledge is attained through "empirical familiarity with objects in this world from which one abstracts universal concepts" developed through a "syllogistic method of reasoning in which observations lead to propositional statements which when compounded lead to further abstract concepts". The intellect itself develops from a material intellect (al-'aql al-hayulani), which is a potentiality "that can acquire knowledge to the active intellect (al-'aql al-fa'il), the state of the human intellect in conjunction with the perfect source of knowledge". So the immaterial "active intellect", separate from any individual person, is still essential for understanding to occur.
Whose idea was 'tabula rasa'?

ANS: Aristotle

QUES: The currentvoltage characteristic of an LED is similar to other diodes, in that the current is dependent exponentially on the voltage (see Shockley diode equation). This means that a small change in voltage can cause a large change in current. If the applied voltage exceeds the LED's forward voltage drop by a small amount, the current rating may be exceeded by a large amount, potentially damaging or destroying the LED. The typical solution is to use constant-current power supplies to keep the current below the LED's maximum current rating. Since most common power sources (batteries, mains) are constant-voltage sources, most LED fixtures must include a power converter, at least a current-limiting resistor. However, the high resistance of three-volt coin cells combined with the high differential resistance of nitride-based LEDs makes it possible to power such an LED from such a coin cell without an external resistor.
How are LEDs similar to other diodes?

the current is dependent exponentially on the voltage
