<h2>
Answer:Option F</h2>
Explanation:
Metals have few number of electrons in their valence shell.
The force with which the nucleus of the metal atom is pulling the electron towards itself is lower on the valence shell because the distance between the nucleus an valence shell is large.
So,there are a lot of free electrons in metals.
When the ends of metals are at different potential,electrons flow from one end to another to balance the potential.This feature of metals allows them to conduct electricity.
Similarly,when the ends of metals are at different temperatures,conduction will take place and electrons are the carriers of conduction.This feature of metals allows them to conduct heat.
So,metals are good conductors of heat and electricity.
Answer:
Part a)

Part b)

Part c)

Explanation:
Part a)
As we know that the gravitational force is given as

so we will have to find the ratio of force on two planets due to star
so here we have



Part b)
Orbital speed is given as

so the ratio of two orbital speed is given as


Part c)
Time period is given as

so the ratio of two time period is given as
