Correct Answer - [T]
`(c_(t))/(c_(0))=e^(-lambdax(1)/(lambda))=((1)/(e))=f_(1)=0.36` (left ) then decay `0.633(f_(1))`
`(c_(1))/(c_(0))=e^(-lambdax(ln2)/(lambda))=2^(-1)=((1)/(2))=f_(2)=0.5` (left)decay `0.5(f_(2)`
`f_(1) gt f_(2)`

The half - line period a radioactive element `X` is same as the mean life time of another radioactive element `Y`. Initially both of them have the sam

Correct Answer - B Given that `(T_(1//2))_(x) = (T_(av))_(gamma)` `rArr (0.693)/(lambda_(x)) = (1)/(lambda_(y)) rArr lambda_(y) (1)/(0.693) lambda_(x)` `rArr lambda_(y) = 1.44 lambda_(x) rArr R_(y) = 1.44 R_(x)` As decay rate of...

A radioactive isotope X with half-life `1.5xx10^(9)` yr decays into a stable nucleus Y .A rock sample contains both elements X and Y in the ratio 1 :

Correct Answer - C Initially whole isotope was X `" "[thereforeX:Y=1:15]` i.e., `N_(0)=1+15=16` and after decaying into Y `implies"We have",N=N_(0)e^(-lamdat)implies1=16e^((0.693)/(15xx10^(9))xxt)` `implies " " 1n ((1)/(16))=e^((1n2)/(t//2))` `implies "The age of the rck,"t=6.00xx10^(9)yr`...

Assertion In one half-life of a radioactive substance more number of nuclei are decayed than in one average life. Reason Average life = Half -life/in

Correct Answer - D (d) Average life is more Hence more nuclei decay in one avaerage life .

A radio isotope `X` with a half life `1.4xx10^(9)` yr decays of `Y` which is stable. A sample of the rock from a cave was found to contain `X` and `Y`

Correct Answer - C According to the question, ratio of X:Y is given = 1: 7 `implies(m_(x))/(m_(y))=(1)/(7)implies7m_(x)=m_(y)` Let the initial total mass is m. `impliesm_(x)+m_(y)=mimpliesm_(y)/(7)+m_(y)=m` `implies(8m_(y))/(7)=mimpliesm_(y)=(7)/(8)m` Only `(1)/(8)` part remains left...

The half-life of a radioactive isotope `X` is `20 yr`. It decays to another element `Y` which is stable. The two elements `X` and `Y` were found to be

Correct Answer - B Ratio of X and Y =1 :7 `m_(x)/(m_(y))=(1)/(7)" "m_(y)=7m_(x)` Let the initial total mass =m `implies m_(x)+m_(y)=m` `implies(m_(y))/(7)+m_(y)=m` `(8m_(y))/(7)=mimpliesm_(y)=(7)/(8)m` Only `((1)/(8))th` part remains undisintegrated, number of half-lives...

The probaility that a certaun radioactive atom would get disintefrated in a time equal to the mean life fo the radioactive sample is

Correct Answer - B Required probability `P(t) = (N_(0)(1-e^(-lambdat)))/(N_(0)) = 1-e^(-lambda((1)/(lambda)))= 0.63`
