इनपुट
¹⁴C: t₁/₂ = 5730 years, after 11,460 years → 25% remains
परिणाम
After 3 half-lives: 12.5% remains
सामान्य गलतियां जिनसे बचना है
- ✕Assuming linear decay (exponential)
- ✕Using wrong half-life values
अक्सर पूछे जाने वाले प्रश्न
Can decay rate change?
No, radioactive decay unaffected by temperature, pressure, chemical state.
