0.3cm
2.7cm
3.4cm
8.3cm
Correct answer is C
\(\frac{1}{f} = \frac{1}{u} + \frac{1}{v} = \frac{1}{3} - \frac{1}{25} = \frac{22}{75}\)
f = 3.4cm
10.00cm
6.00cm
5.00cm
1.50cm
Correct answer is B
\(\frac{1}{u} + \frac{1}{v} = \frac{1}{f} = \frac{1}{15} + \frac{1}{10}\)
u = 6.00
68o
56o
34o
18o
Correct answer is C
c = \(\sin^{-1} \frac{1}{n} = \sin^{-1} \frac{1}{1.8} = 34^o\)
