They are both good conductors if both heat and electricity due to the sea of delocalized electrons that is floating around without getting bonded to an atom.
Such electrons can flow around freely to conduct heat and electricity.
The period of Neptune is 165 years if the semi-major axis is 30.11 using the given formula.
Answer: Option D
<u>Explanation:
</u>
The period of any planet revolutions around the sun can be determined using Kepler third law. As that law states that square to the period of one complete revolution of every planet is equal to cube of semi major axis of that planet. So the formula can be derived as
Where T is the time taken for completing one revolution and a is the semi-major axis of the planet.
As here Neptune's semi major axis is given as 30.11. So the period of Neptune can be determined as follows:
Then take square root of this value:
T = 165 years
Thus, the Neptune takes 165 years for one complete revolution of the sun.
Answer:
The answer is ""
Explanation:
In this question, the halfway indicates the height that is
Using formula:
To answer A you have to find 0.5% of 151 because the heart is 0.5% of total body weight. 151 x 0.5% = 0.755 lbs
Answer:
Rarefactions
Explanation:
The sound waves travel in compressions and rarefactions.
As the name suggests compressions are the areas which particles are closer than their usual positioning.
In rarefactions the vibrating particles can be observed further apart than the usual.
