Physics - Time

Thank You in advance :smile:

A mark scheme says for the definition of radioactive decay constant:
Probability of decay "in unit time".

Is that the same as per unit time?

yeah, the decay constant is a RATE, and rate is always measured per unit of time or 'in' unit of time. Same meaning.

Ok, that makes sense.
