When compared with water, mercury is preferred as a thermometric liquid because
has a higher density
has lower specific heat capacity
exhibits anomalous thermal expansion
contains molecules which have very strong adhesive forces
Correct answer is B
Specific Heat Capacity of mercury and water are 0.14 Jg\(^{-1}\)C\(^{-1}\) and 4.186Jg\(^{-1}\)C\(^{-1}\) respectively.
2 rad s-1
4 rad s-1
5 rad s-1
10 rad s-1
Correct answer is A
= \(\frac{v}{g} = \frac{0.2}{0.05}\)
where w = √ 4 → 2rad s-1
1.5s
3.0s
5.0s
7.5s
Correct answer is B
t = 2\(\frac{(v - u)}{g} = 2\frac{(0 - 15)}{-10}\)
\(\frac{2 \times 15}{10}\) = 3.0s
