if it travels 1.43 km in 1 sec in 1000 it travels x1000 which is 1430
Due to the gravitational pull of earth the asteroid would be pulled towards earth, so the answer is B.
You should note that the melting point of mercury is -38.83°C, while the boiling point is at 356.7°C. Then, that means that there is no latent heat involved here. We only compute for the sensible heat.
ΔH = mCpΔT
The Cp of mercury is 0.14 J/g·°C
Thus,
ΔH = (411 g)(0.14 J/g·°C)(88 - 12°C)
<em>ΔH = 4,373.04 J</em>
