The inner planets are usually rocky because the gravitational pull is stronger closer to the star or in this case the sun. The dust and rocky particles that are left over after a super nova or in a nebula will tend to orbit closer to a proto-star when a solar system is in its early days. In our solar system these planets are Mercury, Venus, Earth and Mars. Gases are less dense and will be less affected by the pull of gravity because rocky particles have more mass. The outer planets are gas giants formed from clouds of gas that would be further out in the spinning disk around a proto-star.
Answer:
300J
The total work done or energy transferred is equal to the product of the force and the displacement in the direction of the force applied.
In this case it would be
300N x 10m to get 3000J.
This energy is transferred in 10 seconds and since power is energy transferred per unit time.
3000J ÷ 10 = 300 Watts or 300 Joules per second.
so your answer is 300 W
The scientist that contributed to the declassification of Pluto as a planet is Mike Brown.
Explanation:
...domains are aligned which creates a magnetic field.
... are not always aligned so the resulting element had no apparent magentism
