Question 2
A cannon fires a shell vertically upwards. The shell leaves the cannon with a speed of 80 m s-1 and a kinetic energy of 480 J.



Question 4
On Fig. 4.1, complete the two graphs to illustrate what is meant by the amplitude A, the wavelength λ and the period T of a progressive wave.


Question 6
An electric current is a flow of charge carriers. In the following list, underline the possible charges for a charge carrier.



Question 7
The graph shows a cross (labelled P) that represents a nucleus P.  Nucleus P decays by emitting an α particle to form a nucleus Q.
