WebDec 4, 2024 · The figures I gave above are in counts per second, but I counted over a longer period. Taking account of the uncertainties in both the count and the time period, the absolute uncertainty in 209 is 5; in 273, 7. This is on the basis that the uncertainty in the time is 1 second, and the uncertainty in the count (C) is √C. evosfnclw1327/evnew/faces/evmain.jspWebVideo transcript. let's solve some numericals on quantum nature of light on photons here's the first one we have a bulb of 100 watt 100 watt light bulb that's giving out a light of … bruce fraser wifeWebsecond翻译:第二(的),第二个(的), 第二名(的), 仅次于第一(的), 另一(的);又一(的), 每隔一个(的), 第二(的),第二个(的), 第二;其次, 时间, 秒, 片 … evo shadowverse bathroomWebEvery second counts, no mistakes. 分秒必争 不容有失.
