Astrophysical jet quiz: 3 questions
Three questions on the Astrophysical jet card, the way WikiCards duels ask them. Pick an answer, the facts are just below.
Find the missing word
Their causes are not yet fully understood, but they are believed to arise from dynamic ______ within accretion disks.
Answer
interactions. Their causes are not yet fully understood, but they are believed to arise from dynamic interactions within accretion disks. From the Astrophysical jet article on Wikipedia.
Which of these Wikipedia articles is read the most in a year?
Answer
Carbon steel. Carbon steel 110,000 · Anvil 87,000 · Astrophysical jet 58,000 · Bedding 39,000 Wikipedia reads over a year.
In a duel, each round asks a question like these about the opposing card, with 15 seconds to answer.
The facts on the card
The card carries these facts from its Wikipedia article.
- When the matter in these streams is flowing at close to the speed of light, the jet is referred to as a relativistic jet, as it demonstrates phenomena predicted by special relativity.
- Astrophysical jets are associated with many types of high-energy astronomical sources, such as black holes, neutron stars and pulsars.
- Their causes are not yet fully understood, but they are believed to arise from dynamic interactions within accretion disks.
Why it is Uncommon
Rarity in WikiCards follows a year of Wikipedia page views: the most read articles become Epic and Legendary cards. The Astrophysical jet article was read about 58,000 times in a year. ATK comes from the length of the article and DEF from its quality, so this card hits with 62 and blocks with 53: each hit it takes is cut by 21 %.
How to get Astrophysical jet
Open packs. Each pack holds five cards drawn from real Wikipedia articles, the rarest last, and the fifth card is always Rare or better. The odds are shown in the game. A free pack arrives every hour and two can wait, and the Coins you win in duels buy more packs.
