Correct Answer Logic:
Using the Arrhenius equation in log form: $\log\frac{k_2}{k_1} = \frac{-\text{slope}}{2.303}\left(\frac{1}{T_2}-\frac{1}{T_1}\right)\cdot2.303$. Since slope of $\log k$ vs $\frac{1}{T}$ is $-\frac{E_a}{2.303R} = -10000$, then $E_a = 10000\times2.303\times8.314$. Using $\log\frac{10^{-4}}{10^{-5}} = -10000\left(\frac{1}{T_2}-\frac{1}{500}\right)$: $1 = -10000\left(\frac{1}{T_2}-0.002\right) \Rightarrow \frac{1}{T_2} = 0.002-0.0001 = 0.0018 \Rightarrow T_2 \approx 556\ K$.

Question 2067
Find the number of common tangents to the circles $x^2+y^2-4x-6y-12=0$ and $x^2+y^2+6x+18y+26=0$.
Correct Answer Logic:
Circle 1: centre $C_1=(2,3)$, $r_1=\sqrt{4+9+12}=5$.
Circle 2: centre $C_2=(-3,-9)$, $r_2=\sqrt{9+81-26}=8$.
Distance $|C_1C_2|=\sqrt{(2+3)^2+(3+9)^2}=\sqrt{25+144}=\sqrt{169}=13$.
Since $|C_1C_2|=13=r_1+r_2=5+8$, the circles are externally tangent. Externally tangent circles have exactly 3 common tangents.

Correct Answer Logic:
At terminal velocity: Viscous force \(= W - F_b\). Buoyancy \(F_b = \rho_{glycerine} \cdot V \cdot g = \frac{1}{2}\rho_{ball} \cdot V \cdot g = \frac{Mg}{2}\). So Viscous force \(= Mg - \frac{Mg}{2} = \frac{Mg}{2}\).

QUESTION #4910
Question 2071
A proposal has been made to trim the horns from rhinoceroses to discourage poachers; the question is _____ rhinoceroses after their horns are trimmed.
Correct Answer Logic:
Whether' (not 'if') is proper in indirect questions. 'The animals' horns' eliminates the ambiguous pronoun 'their' (whose horns — tourists' or rhinoceroses'?). 'To see rhinoceroses' (infinitive of purpose) is more precise than 'and see.' Options D and E incorrectly use 'if.' Options A and B retain ambiguous 'their.'
