The inner planets are closer to the sun, rockier and smaller. The outer planets are further from the sun, bigger and consisting primarily of gas.
Answer:
When two or more forces are acting on a body, then the total of all the forces which causes the resulting effect is the resultant force or net force. As force is a vector, we need to take the vector sum of all the forces to calculate the resultant.
Explanation:
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.
We can answer this one very quickly. From the <em>Law of Conservation of Energy</em>, we know that "Energy can't be created or destroyed.".
So that only leaves us one way to complete the sentence in this question:
"One form of energy can be <em>transformed into</em> another type of energy.
