Half-life of a redioactive substance which disintegrates by 75% in 60 ...
Half-life Calculation:
- The half-life of a radioactive substance is the time it takes for half of the substance to decay.
- Given that the substance disintegrates by 75% in 60 minutes, it means that only 25% of the substance remains after 60 minutes.
Calculation:
- Let's assume the initial amount of the substance is 100 units.
- After 60 minutes, only 25 units of the substance remain (25% of 100).
- This implies that 75 units (75%) have decayed in 60 minutes.
Half-life Calculation:
- Since 75 units have decayed in 60 minutes, it means that 50 units (half of 100) would decay in the first half-life period.
- Therefore, the half-life of the substance is 60 minutes.
Therefore, the correct answer is option B) 30 min.
