In a television programme to illustrate scientific models, a presenter fires a gun many times at a bale of hay. Two small cannon balls are embedded within the hay some distance apart from each other. The hay bale measures approximately 2 m × 2 m × 2 m and the cannon balls are made of iron, approximately spherical, and about 5 cm in diameter. What might the presenter be illustrating?

1. Aα-particle scattering
2. Bβ– decay
3. Cconservation of momentum
4. Ddouble-slit interference
