Problem: Capacitor:

If a capacitor is driven with a time-varying voltage that changes rapidly enough, at some frequency the polarization of the dielectric cannot follow the voltage. As an example of the origin of this mechanism, the internal microscopic dipoles contributing to the dielectric constant cannot move instantly, and so as frequency of an applied alternating voltage increases, the dipole response is limited and the dielectric constant diminishes. A changing dielectric constant with frequency is referred to as dielectric dispersion, and is governed by dielectric relaxation processes, such as Debye relaxation. Under transient conditions, the displacement field can be expressed as (see electric susceptibility):

 What is an example of an undielectric relaxation process?

A: unanswerable


Problem: Meanwhile, on 10 October 1950, the 89th Tank Battalion was attached to the 1st Cavalry Division, increasing the armor available for the Northern Offensive. On 15 October, after moderate KPA resistance, the 7th Cavalry Regiment and Charlie Company, 70th Tank Battalion captured Namchonjam city. On 17 October, they flanked rightwards, away from the principal road (to Pyongyang), to capture Hwangju. Two days later, the 1st Cavalry Division captured Pyongyang, the North's capital city, on 19 October 1950. Kim Il Sung and his government temporarily moved its capital to Sinuiju – although as UNC forces approached, the government again moved – this time to Kanggye.
Who did not capture the city of Namchonjam?

Answer: KPA

High hopes for the AFL waned when interim commissioner Ed Policy announced his resignation, citing the obsolescence of his position in the reformatted league. Two weeks later, the Los Angeles Avengers announced that they were formally folding the franchise. One month later, the league missed the deadline to formally ratify the new collective bargaining agreement and announced that it was eliminating health insurance for the players. Progress on the return stalled, and no announcements were made regarding the future of the league.
How long after the shuttering of the Avengers did the league fail to ratify the new collective bargaining agreement?
A: One month


Context and question: To prevent this problem, in one implementation of destination control, every user gets an RFID card to identify himself, so the system knows every user call and can cancel the first call if the passenger decides to travel to another destination to prevent empty calls. The newest invention knows even where people are located and how many on which floor because of their identification, either for the purposes of evacuating the building or for security reasons. Another way to prevent this issue is to treat everyone travelling from one floor to another as one group and to allocate only one car for that group.
Newer systems know where and how many people are at a location for what reasons?
Answer: either for the purposes of evacuating the building or for security reasons


Question: It was at Port Said that Nasser saw a confrontation with the invading forces as being the strategic and psychological focal point of Egypt's defense. A third infantry battalion and hundreds of national guardsmen were sent to the city as reinforcements, while two regular companies were dispatched to organize popular resistance. Nasser and Boghdadi traveled to the canal zone to boost the morale of the armed volunteers. According to Boghdadi's memoirs, Nasser described the Egyptian Army as "shattered" as he saw the wreckage of Egyptian military equipment en route. When British and French forces landed in Port Said on 5–6 November, its local militia put up a stiff resistance, resulting in street-to-street fighting. The Egyptian Army commander in the city was preparing to request terms for a ceasefire, but Nasser ordered him to desist. The British-French forces managed to largely secure the city by 7 November. Between 750 and 1,000 Egyptians were killed in the battle for Port Said.
Is there an answer to this question: Who was ultimately able to claim victoy in Port Said?

Answer: British-French forces

Kathmandu is dissected by eight rivers, the main river of the valley, the Bagmati and its tributaries, of which the Bishnumati, Dhobi Khola, Manohara Khola, Hanumant Khola, and Tukucha Khola are predominant. The mountains from where these rivers originate are in the elevation range of 1,500–3,000 metres (4,900–9,800 ft), and have passes which provide access to and from Kathmandu and its valley. An ancient canal once flowed from Nagarjuna hill through Balaju to Kathmandu; this canal is now extinct.
How many rivers travel through Kathmandu?
A:
eight
