10.02cm3
10.04cm3
10.06cm3
10.20cm3
102.00cm3
Correct answer is C
3 x \(\alpha\) = \(\frac{V_2 - V_1}{\Delta \theta \times V_1}\)
3 x 2 x 10-5 = \(\frac{V_2 - 10}{10 \times 100}\)
V2 = 10.06cm3

250W
400W
500W
Correct answer is E
Power = \(\frac{\text{force x distance}}{\text{time}}\)
= \(\frac{50 × 10 × 5}{5}\)= 500W

Correct answer is B
Using V = at + u
V = (-4 x 10) + 44
= 4ms-1

400cm3
Correct answer is A
\(\frac{P_1V_1}{T_1}\) = \(\frac{P_2V_2}{T_2}\)
P2 = 2P ; T1 = 2T2
therefore, \(\frac{P_1 \times 1000}{2T_2}\) = \(\frac{2P_2 \times V_2}{T_2}\)
= 25cm
