Instructions to candidates:

Turn to page 20 of the question paper and look at question 18(b)(i).

In line 4, cross out the ‘d’ and replace with ’x’.

The line: where k is a constant and d is measured in m

should now read: where k is a constant and x is measured in m


AND

Turn to page 32 of the question paper and look at question 23(b).

In line 2, cross out the ‘s’ in ‘Hubbles’. Then cross out ‘10-19’ and replace with ‘10-18’.

The line: Hubbles constant Ho = 2.5 x 10-19 s-1
should now read: Hubble constant Ho = 2.5 x 10-18 s-1
