Question

20% radioactive sample decay in time t.how much sample decay in time 2t?​

Answer 1

Answer:

40%

Explanation:

if time t gives 20% radioactive decay ,we can equate it as

t=20%

according to mathematical theories LHS(left hand side) should be equal to RHS(right hand side)

SO,

t=20%

2t=20%*2

2t=40%

Answer 2

Answer:

here answer is 40 percentage

because u know left hand side is equal to right hand side, this is according to maths theory.....

if radioactive sample decay time is 20 percent

then

t= 20 percentage

2t= 20 percentage multiply with 2

so 2t= 40 percentage
