Decay Percentage Formula
The formula to calculate the decay percentage is:
\[
\text{DP} = \frac{\text{TD}}{\text{OA}} \times 100
\]
where:
- DP is the decay percentage (%),
- TD is the total decay,
- OA is the original starting amount.
Example Calculation
Let's calculate the decay percentage using an example:
- TD (Total Decay) = 20
- OA (Original Starting Amount) = 80
Using the formula:
\[
\text{DP} = \frac{20}{80} \times 100 = 25 \%
\]
Common FAQs
What is decay percentage used for?
Decay percentage measures the reduction in value, amount, or quantity of a substance over time. It’s essential in various fields like physics, chemistry, and economics to understand the rate of decline.
How does decay percentage differ from decay rate?
Decay percentage indicates the percentage decrease relative to the initial amount. The decay rate refers to the speed at which a substance decreases over time.
Can decay percentage exceed 100%?
No, decay percentage cannot exceed 100%, as it represents the percentage of the original amount that has decayed.
