To film in an airside location, all visitors must go through security, the same as passengers, and be accompanied by a full airside pass holder and have their passport with them at all times. Filming can not be undertaken in Security, at Immigration/Customs, or in Baggage Reclaim.

Question: The essential usefulness of a transistor comes from its ability to use a small signal applied between one pair of its terminals to control a much larger signal at another pair of terminals. This property is called gain. It can produce a stronger output signal, a voltage or current, which is proportional to a weaker input signal; that is, it can act as an amplifier. Alternatively, the transistor can be used to turn current on or off in a circuit as an electrically controlled switch, where the amount of current is determined by other circuit elements.
Is there an answer to this question: Where would an electrically controlled switch be located?

Answer: unanswerable

Question: Hisham suffered still worse defeats in the east, where his armies attempted to subdue both Tokharistan, with its center at Balkh, and Transoxiana, with its center at Samarkand. Both areas had already been partially conquered, but remained difficult to govern. Once again, a particular difficulty concerned the question of the conversion of non-Arabs, especially the Sogdians of Transoxiana. Following the Umayyad defeat in the "Day of Thirst" in 724, Ashras ibn 'Abd Allah al-Sulami, governor of Khurasan, promised tax relief to those Sogdians who converted to Islam, but went back on his offer when it proved too popular and threatened to reduce tax revenues. Discontent among the Khurasani Arabs rose sharply after the losses suffered in the Battle of the Defile in 731, and in 734, al-Harith ibn Surayj led a revolt that received broad backing from Arabs and natives alike, capturing Balkh but failing to take Merv. After this defeat, al-Harith's movement seems to have been dissolved, but the problem of the rights of non-Arab Muslims would continue to plague the Umayyads.
Is there an answer to this question: Who was able to capture Merv?

Answer:
unanswerable
