TīmeklisNitrogen-13 and oxygen-15 are produced in the atmosphere when gamma rays (for example from lightning) knock neutrons out of nitrogen-14 and oxygen-16: . 14 N + γ → 13 N + n 16 O + γ → 15 O + n. The nitrogen-13 produced as a result decays with a half-life of 9.965(4) min to carbon-13, emitting a positron.The positron quickly annihilates … TīmeklisIf the ratio of the sum of first n terms of two A.P.'s is (7n+1): (4n+27), find the ratio of their mth terms.

Ex 9.2, 9 - Sums of n terms of two APs are in ratio 5n+4: 9n+6
TīmeklisGiven ratio of sum of n terms of two AP’s = (7n+1): (4n+27) Let’s consider the ratio these two AP’s mth terms as am : a’m → (2) Recall the nth term of AP formula, an = a + (n – 1)d Hence equation (2) becomes, am : a’m = a + (m – 1)d : a’ + (m – 1)d’ On multiplying by 2, we get am : a’m = [2a + 2 (m – 1)d] : [2a’ + 2 (m – 1)d’] Tīmeklis2024. gada 4. dec. · If the ratio of the sums of first n terms of two AP's is (7n+1) : (4n + 27), find the ratio of their mth terms. cbse class-10 1 Answer +2 votes answered Dec … TīmeklisIf the Ratio of the Sum of the First N Terms of Two A.Ps is (7n + 1) : (4n + 27), Then Find the Ratio of Their 9th Terms.
