Correct answer is C
n = \(\frac{360}{\theta}\) - 1
= \(\frac{360}{60} -1\)
= 6 - 1 = 5
104.4m
207.9m
415.8m

S = \(\frac{vt}{2} = \frac{330 \times 1.26}{2} = 207.9\)
2.50m
1.95m
1.50m
0.45m
Correct answer is D
Real depth = n x apparent depth
= 1.3 x 1.5 = 1.95m
Apparent displacement = 1.95 - 1.5 = 0.45m
0.05m
0.15m
