Tātaitai Hapa-Wā
Ko te whakawāteatanga irawhitiwhiti: ka kitea te nui e toe ana, te wā e haere ana, te wā haurua rānei, me te ānau whakawāteatanga.
Ka whakahōutia ngā hua i te wā e tātuhi ana.
Mo tēnei tātaitai
calculator reports the half-life constant λ = ln2 / t½ ≈ 0.693 / ln2 (the probability a given atom decays per unit time) and the mean lifetime τ = 1 / λ = t½ / ln2 (the average time an individual atom survives). The calculator reports the half-life constant λ = ln2 / t½ ≈ 0.693 / ln2 (the probability a given atom decays per unit time) and the mean lifetime τ = 1 / λ = t½ / ln2 (the average time an individual atom survives per unit time) and plots the decay curve. The calculator reports the half-life constant λ = ln2 / t½ ≈ 0.693 / ln2 (the probability a given atom decays per unit time) and the half-life constant λ = ln2 / t½ ≈ 0.693 / ln2 (the average time an individual atom survives).As a working example, carbon-14 has a half-life of 5,730 years, and the half-life constant λ = 100 × (½)^(2000 / 5730) ≈ 78.5 units after 2,000 years.As a working example, carbon-14 has a half-life of 5,730 years, and the half-life constant λ = ln2 / t½ ≈ 0.693 / ln2 (the probability a given atom decays per unit time).As a working example, carbon-14 has a half-life constant λ = 100 × (½)^(2000 / 5730) ≈ 78.5 units after 2,000 years.As a working example, carbon-14 has a half-life constant λ = ln2 / t½ ≈ 0.693 / ln2 (the probability a given atom decays per unit time) and the mean lifetime τ = 1 / λ = t½
Ko nga pātai e pā ana
He aha te tātai o te whakawāteatanga o te wā?
The amount left after time t is N = N₀ × (½)^(t/t½). After one half-life half remains, after two a quarter, after three an eighth, and so on.
He aha te tauwhāinga o te whakawāteatanga me te wā ora?
Ko te tauwhāiti whakapeka λ = ln2 / t½ ≈ 0.693 / t½, te tūponotanga o te whakapeka i ia wa kotahi. Ko te wā ora tau tōtika τ = 1 / λ = t½ / ln2 ko te wā tau tōtika e ora ana te ngota — tata ki te 1.44 te wā haurua.
Ka kitea e au te wā haurua mai i ngā inenga e rua?
He. Ka whakatū "whakataua mō" ki te wā haurua, ka tāuru i ngā nuinga tuatahi me ngā toenga, tae atu ki te wā kua tae; Ka whakaoti te utauta t½ = t × ln2 / ln(N₀/N).
He pēhea te pātahitanga o te rārangi waro-14 ki te wā haurua?
Ka whakapeka te waro-14 me te ora hāwhe o te 5,730 tau, nō reira ko te inenga ko te nui o te C-14 e toe ana i roto i tētahi tauira ora kotahi, ka whakatata i te wā. Mai i ngā wae 100, tata ki te 78.5 e noho ana i muri i te 2,000 tau, ā, tata ki te hāwhe i muri i te 5,730 — te take o te rārangi radiocarbon.
He aha nga wae e whakamahia ana e te wā me te wā haurua?
Ko ētahi wae, tae noa ki te wā e haere ana me te wā haurua e tiritiri ana. Hei tāuru i ngā tau e rua, i ngā takirua rānei; Ko te ōwehenga t / t½ ko te mea katoa e hira ana, ā, ka hoki mai ngā hua ki taua wae kotahi.
He nui te toenga i muri i ētahi wā taurua?
Ka whakarea e te haurua mō ia wā haurua: 50% i muri i te kotahi, 25% i muri i te rua, 12.5% i muri i te toru, 6.25% i muri i te whā. I muri i te tekau tau o te wā haurua i raro i te 0.1% e noho ana, nā reira ko te "whā tekau tau o te wā haurua" he ture noa iho mō te haere tika.
E whakawhirinaki ana te wā haurua ki te nui o te rawa ka tīmataria e au?
Kāore. He āhuatanga pūmau o te isotope, i te āhua o te rahi tauira, te mahana, te āhua matū rānei. Mēnā ka tīmata rānei ki te rārangi, ki te tāone rānei, ka whakawāteatia te haurua i roto i te wā haurua kotahi — ko te mea e hanga ana i tētahi karaka tika.
