Radioactive Activity Calculator vs Simple Pendulum Calculator
Two calculators for the same neighbourhood of questions. Here is what each measures, what you feed in, and where you'd reach for one over the other.
Radioactive Activity Calculator
Computes the radioactive activity of a sample in curies from its atom count and decay constant. Use this when characterizing radioisotope sources for medical physics, nuclear waste inventory, or laboratory safety.
- Answers
- Activity (Ci)
- Inputs
- Number of Atoms, Decay Constant
Simple Pendulum Calculator
Computes the period and frequency of a simple pendulum from its length and gravitational acceleration. Use it for clock design, physics experiments, and comparing pendulum behaviour on different planets.
- Answers
- Period (s)
- Inputs
- Pendulum Length, Angular Amplitude, Gravitational Acceleration, Calculation Method
