, 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 The wavelength of a line in the spectrum produced by a distant star is found to be shorter
than the wavelength of the corresponding line in the spectrum produced by the Sun.
This is because the distant star is
A cooler than the Sun.
B hotter than the Sun.
C moving away from the Earth.
D moving towards the Earth.

, 3 Recent determinations of the Hubble constant give a much smaller value than that
originally obtained.
Compared to original ideas about the universe, the smaller value of the Hubble constant
leads to the conclusion that the universe is
A more dense.
B less dense.
C older.
D younger.

5 The Millennium Bridge is a pedestrian suspension bridge across the River Thames in
London. The bridge had to be closed soon after its opening because of a large swaying
pTl
motion created by people walking across it. A damping mechanism was installed to fix
the problem.
mF
The damping mechanism
A increased the stiffness of the bridge.
xReA
B increased the natural frequency of the bridge.
C dissipated energy from the bridge.
D decreased the forcing frequency on the bridge.
