Radioactive decay
N = N₀e^(−λt)
Where: N = number of turns / normal force (N), N₀ = initial number of nuclei, λ = wavelength (m) / decay constant, t = time (s)
Solved example
Given: N_0 = 7, lamda = 5, t = 10
Find: N (number of turns / normal force (N))
- Formula: N = N₀·e^(-λ·t)
- Substitute the values: N = 7·e^(-10·5)
- Result: N = 0
Answer: N = 0
