Expert Solution
Step 1

Sol:-

The relationship between tp and tq can be derived from the general formula for the decay of a radioactive substance, which is:

m = mo * exp(-λt)

where m is the mass of the radioactive substance at time t, mo is the initial mass of the substance, λ is the decay constant, and exp(-λt) is the decay factor.
