72.0cm
74.5cm
75.1cm
76.0cm
Correct answer is D
Using, P1V1 = P2V2
(75 - 73.5) x 8 = (X - 74) x 6
X = 76cm
126.50cm3
126.25cm3
126.00cm3
125.00cm3
Correct answer is A
Recall that: Volume = L * L * L → 5 * 5 * 5 = 125
Y = \(\frac{V_2 - V_1}{V_1 \times \theta}\)
3 x 4 x 10-5 = \(\frac{V_2 - 125}{125 \times (120 - 20)}\)
V2 = 126.50cm3
22.5oC
29.0oC
29.0oC
100.0oC
Correct answer is A
20cm .... 100oC
4.5cm .... \(\theta\)
0cm ....0oC
\(\frac{4.5 - 0}{20 - 0}\) = \(\frac{0 - 0}{100 - 0}\)
\(\theta\) = 22.5oC
0.125cm-1
0.250gcm-1
0.625cm-1
2.500cm-1
Correct answer is C
Height below liquid = 1 - \(\frac{1}{5}\) = \(\frac{4}{5}\)
volume of cube = 103cm3
volume of liquid displaced = \(\frac{4}{5}\) x 1000
= 800cm3
density of liquid displaced;
= \(\frac{500}{800}\)
= 0.625cm-1
1.12cm
2.14cm
2.24cm
2.52cm
Correct answer is C
\(\frac{F_1}{e_1}\) = \(\frac{F_2}{e_2}\)
\(\frac{5}{0.56}\) = \(\frac{20}{e_2}\)
e2 = 2.24cm
