80 kg of a radioactive material reduces to 10 kg in 1 h. The decay constant of the material is

The decay constant of a radioactive sample

The decay constant of a radioactive sample

In a radioactive material the activity at time t_1 is R_1 and at a later time t_2 , it is R_1 . If the decay constant of the material is lamda , then

15/16 part of radioactive material decays in 10 days. After how many days 3/4 part of the material will decay? Find also the half life of the radioactive material.

If the quantify of radioactive material reduces by 10% in 5days then the quantity that remains after 20 days will be -

Half life of a radioactive material is 3600 years. Calculate the decay constant.

In a radioactive material the activity at time t_(1) is R_(1) and at a later time t_(2) , it is R_(2) . If the decay constant of the material is lambda , then

In a radioactive material the activity at time t_(1) is R_(1) and at a later time t_(2) , it is R_(2) . If the decay constant of the material is lambda , then
