RobinHez:dude this is wrong, the question says how many atoms are disintegrated, not how many atoms are left after disintegration, therefore the answer is N/8. |
Re: UNIBEN STUDENTS ADMISSION THREAD, 2015/2016 by RobinHez(m): 11:41am On May 12, 2015 |
lordkvng:Actually, I think N/8 is the number of atoms left... Mass of atom/2 =mass after disintegration. So after 3 half-lives ->,N/2, N/2/2, N/2/2/2 we have N/8 which (I think) is the mass left after the third half-life. To now get the mass that has (already) disintegrated, we take away the current mass from the initial mass.....N-N/8 |

RobinHez: hmm... From ur question-->>1st set is 3,4,x,y & d average is 4.5, So dats; (3+4+X+Y)/4=4.5----equation 1 2nd set,2X,y,4,3 & average is 5, so dats; (2X+y+4+3)/4=5----equation2 Bringin dem together, (7+X+y)/4=4.5=>>7+X+y=18==>>X+Y=11...equat1 (2X+y+7)/4=5=>>2X+y+7=20==>>2X+y=13...equat2 •°•equat1 can still b X=11-y. Subst dat in equat2, 2(11-y)+y=13==>>22-2y+y=13. That's 22-y=13=>-y=-9...so e be like say y=9 ![]() •°•subst, y in equation 1. X+Y=11=>>X+9=11 E cum b like say X=2. ß |

RobinHez:N/8 is the mass that disintegrated, to find the mass left After disintegration, 8/8-n/8 =7N/8.. That's what u just did. and it's wrong. |
Re: UNIBEN STUDENTS ADMISSION THREAD, 2015/2016 by dharay99: 12:43pm On May 12, 2015 |
RobinHez: oya since we get am, show ur workings cuz me i no get any workings. |
Re: UNIBEN STUDENTS ADMISSION THREAD, 2015/2016 by RobinHez(m): 12:46pm On May 12, 2015 |
Charles487:Don't worry, I believe she's working on it and u'll get it in no-time...meanwhile I've been scouting the web for it also; its not easy to get online..but don't worry. |

dharay99: C.P + 10% of C.P = S.P I.E. C.P + C.P/10 = N18700 Factorizing, we have C.P(1 + 1/10) =N18,700 C.P (1 + 0.1) = N18700 =1.1C.P = N18,700 Dividing both sides by 1.1 C.P = N17,600!! So to a profit of 18% would be 18/100 x 17000 Which equals N3,060 Therefore the selling price-->c.p + profit =N(17000+3060) =N20,060. .C. |

lordkvng:If ur theory is true, then how would we go abt this question below? The half-life of an element is 12hrs. If the initial mass is 50g, what mass will be left-after 2days? |
