Physics
Radioactive Decay/Half Life
Alpha particle
2 protons 2 neutrons
Least penetrading
Positively charged
Beta Particle
High energy electrons
Can penetrate air and paper
negitivaly charged
Gamma particle
electromagnetic radiation - short wave lenght
Most penetrating (xrays)
Half Life
the time it takes for the number of nuclei of the isotope in a sample to halve
the time it takes for the count rate from a sample containing the isotope to fall to half its starting level
Spring Constant Calculations
F = ke
F = force in newtons (n)
k = 'spring constant' (newtons per metres)
e = extension in metres
Potential Difference/Power
potential difference = energy/charge
