Question 1

The graph shows the force a club exerts on a 0.0459 kg golf ball, initially at rest, against time. What is the ball's speed as it leaves the club?

Question 2

The graph shows the emf from a small generator whose coil turns at a steady rate in a uniform magnetic field. The coil is then turned twice as fast. What are the new peak emf and the new period?

Question 3

Energy levels of a hydrogen atom, from n = 1 (the ground state) to n = 4.
Level	Energy (eV)
n = 4	−0.85
n = 3	−1.51
n = 2	−3.40
n = 1	−13.6

The table gives energy levels of a hydrogen atom. What is the wavelength of the photon emitted when the electron moves from n = 3 down to n = 2? Take h = 6.63 × 10⁻³⁴ J s, c = 3.00 × 10⁸ m s⁻¹ and 1 eV = 1.60 × 10⁻¹⁹ J.

Are past papers still useful?

Yes, for timing and question style. Check that a question's content is in the current subject outline before you rely on it.
