The heat capacity of a calorimeter is the amount of energy required to
change the temperature of 1kg of the calorimeter by 1k
change 1kg mass of the calorimeter to liquid at the same temperature
change the temperature of the calorimeter
melt the calorimeter into liquid at a constant temperature

4mm
3mm
2mm
1mm
Correct answer is B
\(I_2 - I_1 = I_1, \theta\alpha - 1 \times 100 \times 3 \times 10^{-5}\)
= 3 x 10-3m
= 3mm
14.0\(\Omega\)
6.7\(\Omega\)
3.2\(\Omega\)
2.7\(\Omega\)
Correct answer is B
\(\frac{R - 4}{10 - 4} = \frac{45 - 0}{100 - 0}\)
R = \(\frac{670}{100} = 6.7\Omega\)

2.0kgms-1
10.0kgms-1
5.0kgms-1
2.5kgms-1
Correct answer is B
I = Ft = m(v - u) = 5 x 2
= 10kgms-1
