Logarithmic decrement quiz: 3 questions
Three questions on the Logarithmic decrement card, the way WikiCards duels ask them. Pick an answer, the facts are just below.
Which of these cards hits hardest (highest ATK)?
Answer
Skew-T log-P diagram. Skew-T log-P diagram 43 · Logarithmic decrement 40 · Ketolide 37 · Human lung microvascular endothelial cell 34 ATK in WikiCards.
Which of these Wikipedia articles is read the most in a year?
Answer
Limitless. Limitless 44,000 · Logarithmic decrement 13,000 · Fesenkov 260 · Flavonoid 4'-O-methyltransferase 150 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.
- The method of logarithmic decrement becomes less and less precise as the damping ratio increases past about 0.5, it does not apply at all for a damping ratio greater than 1.0 because the system is overdamped.
Why it is Common
Rarity in WikiCards follows a year of Wikipedia page views: the most read articles become Epic and Legendary cards. The Logarithmic decrement article was read about 13,000 times in a year. ATK comes from the length of the article and DEF from its quality, so this card hits with 40 and blocks with 11: each hit it takes is cut by 4 %.
How to get Logarithmic decrement
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.
