1 (a) Nuclear fusion is a process that releases energy.
Which of these statements applies to a nuclear fusion reaction?
(1)
A it emits daughter nuclei
B it is a controlled chain reaction
C it produces radioactive waste
D it requires high temperature and pressure
(b) In the Sun, four protons start the process of nuclear fusion.
These protons combine and finally produce a helium nucleus.
The helium nucleus has a smaller mass than the four protons.
This difference in mass is converted to energy.
Four protons have a total mass of 6.69 10
27 kg .
A helium nucleus has a mass of 6.64 10
27 kg .
Calculate the percentage of the original mass that has been converted to energy.

Explain how red shift in light, received from galaxies at different distances
from the Earth, supports the idea that the Universe is expanding.
