Answer:

B. "Should the government..."; the answer to this relies on subjective input (what the audience thinks the government should do).

Explanation:

Think about the differences between statements that are subjective and objective. If you look at A, C, or D, these results of these experiments are all objective:

A) The amount of electricity generated by a power plant isn't "arguable"; it's a definite value that I can't just "make up" or "think" is correct/valid.

C) The byproducts generated by manufacture aren't "arguable" either; if a byproduct is heat, there's no subjective input.

D) Try to use the above reasoning for D!

Two substances A and B, initially at different temperatures, are thermally isolated from their surroundings and allowed to come
Elden [556K]

Answer:

B

Explanation:

For solving this we need a heat balance

Q_{a} = Q_{b}\\m_{a}*C_{a}*\Delta T_{a} = m_{b}*C_{b}*\Delta T_{b}

By changing the corresponding relations, we have

m_{a}*C_{a}*\Delta T_{a} = \frac{1}{2}m_{a}*4C_{a}*\Delta T_{b} \\\\\\

By cancelling similar factor, we obtain

\Delta T_{a} = 2 \Delta T_{b}\\\frac{\Delta T_{a}}{\Delta T_{b}} = 2\\

Which means that the change of temperature in A is twice the change of B
