How did the temperature structure of the solar nebula determine planetary composition?

STALIN [3.7K]

Explanation:

The temperature of the solar nebula was decreasing as it moved away from its center. Therefore, only heavy elements could condense in the inner solar system and terrestrial planets could not form with light elements, such as gases. In the outer solar system, the Jovian planets formed mostly with gases, since temperatures were too low to allow rocky compositions.

KengaRu [80]

Answer:

Efficiency

Explanation:

The amount of mechanical work an engine can do per unit of heat energy it uses is called its efficiency.
It is also defined as the output divided by the total electrical power consumed.
In terms of heat, efficiency of engine is given by :

$\eta=1-\dfrac{Q_o}{Q_i}$

$Q_o\ and\ Q_i$ are output heat and input heat respectively.

Hence, the correct option is (d) "efficiency"
