, SECTION A
Answer ALL questions.
For questions 1–10, in Section A, select one answer from A to D and put a cross in
the box . If you change your mind, put a line through the box and then mark
your new answer with a cross .
1 Radioactive decay is said to be a spontaneous process.
This means that
A we cannot know when a nucleus will decay.
B we cannot know which nucleus will decay next.
C we cannot know how many nuclei will decay.
D we cannot influence when a nucleus will decay.

2 A standard candle, within a nearby star cluster, is a distance D from the Earth. It
produces a radiation flux F at the surface of the Earth.
The flux at the surface of the Earth, for a standard candle of the same luminosity in a
second star cluster, is 4F.
The distance of the second star cluster from the Earth is
A 4D
B 2D

,3 In an experiment to measure the activity of a radioactive source the measured activity
should always be corrected by
A adding the background count.
B adding the background count rate.
C subtracting the background count.
D subtracting the background count rate.

4 Exoplanets are planets orbiting stars other than our own Sun. Most exoplanets discovered
so far are giant planets similar to the planet Jupiter. The exoplanet Kepler-7b has a mass
about 0.43 times the mass of Jupiter, and a radius about 1.6 times the radius of Jupiter.
Take the gravitational field strength at the surface of Kepler-7b to be gK, and the
gravitational field strength at the surface of Jupiter to be gJ.
gK
The ratio is

A 0.17
B 0.27

5 Star A has twice the radius of star B but only half the surface temperature.
The ratio of the luminosity of star A to luminosity of star B is
A 1:4
B 1:2
C 2:1
D 4:1

following terms definitely describes the oscillations of the bridge?
The oscillations of the bridge are
A free.
B forced.
C natural.
D resonant.
(Total for Question 6 = 1 mark)
7 The damping force acting on an oscillating system is always
A in the opposite direction to the acceleration.
B in the opposite direction to the velocity.
C in the same direction as the acceleration.
D in the same direction as the velocity.
