Two radioactive materials have decay constant `5lambda&lambda`. If initially they have same no. of nuclei. Find time when ratio of nuclei become `((1)/(e))^(2)` :
Two radioactive materials X_(1) and X_(2) have decay constant 11 lambda and lambda respectively. If initially they have same number of nuclei, then ratio of number of nuclei of X_(1) to X_(2) will be (1)/(e^(2)) after a time
Two radiactive material A_(1) and A_(2) have decay constants of 10 lambda_(0) and lambda_(0) . If initially they have same number of nyclei, the ratio of number of their undecayed nuclei will be (1//e) after a time
Two radioactive material A_(1) and A_(2) have decay constants of 10 lambda_(0) and lambda_(0) . If initially they have same number of nuclei, then after time (1)/(9 lambda_(0)) the ratio of number of their undecayed nuclei will be
Two radioactive nuclides A and B have decay constant 10lambda and lambda respectively. If initially they have same number of nuclei, calculate the ratio of nuclei of A and B after a time 1//9lambda
Two radioactive materials X_(1) and X_(2) have decay constants 5 lambda and lambda respectively. If initially they have the same number of nuclei, then the ratio of the number of muclei of X_(1) to that of X_(2) will be 1/e after a time
Two radioactive materials X_(1) and X_(2) have decay constants 10 lamda and lamda respectively. If initially they have the same number of nuclei, if the ratio of the number of nuclei of X_(1) to that of X_(2) will be 1//e after a time n/(9lamda) . Find the value of n ?
Two radioactive materials X_1 and X_2 have decay constants 10 lamda and lamda respectively. If initially they have the same number of nuclei, then the ratio of the number of nuclei of X_1 to that of X_2 will be 1//e after a time.
