4.57 minutes
5.02 minutes
7.30 minutes
10.04 minutes
Correct answer is A
t = \(\frac{MC\theta}{2} = \frac{1.5 \times 4200 \times 50}{5 \times 230}\)
= 273.91s or 4.57 mins
273m3
546m3
8193
10923
Correct answer is B
\(V_2 = V_1(B\theta + 1) = 273 (\frac{1}{373} \times 273 + 1)\)
= 546m3
20\(\alpha\)
200\(\alpha\)
2000\(\alpha\)
20000\(\alpha\)
Correct answer is A
\(L_2 - L_1 = \alpha_1 (\theta_2 - \theta_1) = \alpha \times 0.5 \times 40 = 20 \alpha\)
