Correct answer is C
Atmospheric pressure equivalence of 10m of water
: \(\frac{p_2+10}{p_1+10}\)
= \(\frac{40+10}{20+10\)
= \(\frac{50}{30}\) = 1.67
2.0 x 10\(^2\)Jkg\(^-1\)K\(^-1\)
2.0 x 10\(^2\)Jkg\(^-1\)
4.0 x 10\(^4\)Jkg\(^-1\)K\(^-1\)
4.0 x 10\(^4\)Jkg\(^-1\)
Correct answer is C
Heat energy = Electrical Energy
MC\(\theta\) = power x time
5 x 1 x 10\(^{-2}\) x C = 100 x 20
C = \(\frac{200}{5 \times 10^2}\)
= 4 x 10\(^4\) J/kg/\(^oC\)
55.3\(^o\)C
23.3\(^o\)C
49.0\(^o\)C
16.43\(^o\)C
Correct answer is B
\(\frac{49 - 0}{210 - 0}\) = \(\frac{\theta - 0}{100 - \theta}\)
\(\frac{49}{210} = \frac{\theta}{100}\)
49 x 100 = 210 x \(\theta\)
\(\theta = \frac{4900}{210}\) = 23.3\(^o\)

Correct answer is A
3 x \(\alpha\) = \(\frac{V_2 - V_1}{V_1 \times \Delta \theta}\)
3 x 2 x 10\(^{-5}\) = \(\frac{V_2 - 10}{100 \times 10}\)
V\(_2\) = (100 x 10 x 3 x 2 10\(^{-2}\)) + 10
= 10.06 cm\(^3\)
