Assuming it is on a horizontal surface:
friction = μR
R = 20g (g is gravity 9.81)
so Friction = 0.085 x 20g
Work done is force x distance
so Work done = 0.085 x 20g x 28
= 466.956 J
Answers A and C can be automatically eliminated because evaporation has to do with the water cycle and magnetism has to do with electric current and such. Next we can eliminate B or distillation because it also has to do with water/liquids. Therefore, the answer is D or filtration because it is the only answer left.
I hope this helps!
What happens to end a of the rod when the ball approaches it closely this first time is; It is strongly attracted.
<h3>Electrostatics</h3>
I have attached the image of the rod.
We are told that the ball is much closer to the end of the rod than the length of the rod. Thus, if we point down the rod several times, the distance of approach will experience no electric field and as such the charge on end point A of the rod must be comparable in magnitude to the charge on the ball.
This means that their fields will cancel.
Finally, we can conclude that when a charge is brought close to a conductor, the opposite charges will all navigate to the point that is closest to the charge and as a result, a strong attraction will be created.
This also applies to a strong conducting rod and therefore it is strongly attracted.

Explanation:
The orbit of the planet is considered to be stable and does not change over time. This means that the force of gravity and inertia are perfectly balanced. Leading to forward motion of Planet and moons under force of gravity of some other large body(Most probably stars).This is in turns leads to formation of orbit.
Answer:
Humanity's "big science" experiments like the "Large Hadron Collider (LHC)" are by themselves not problems to be condemned. They show man's unending quests for answers: to discover their environment and its origin. Similar philosophical quests were summed up by St. Augustine, who noted that "our souls are restless until they find rest in GOD."
Humanity will continue such experiments, the costs notwithstanding, until we come to faith in Yahweh, who is the creator of heaven and earth and in His Son. When that faith is attained, our understanding will become complete. We can then divert the billions to discover the future and not the past.
Explanation:
That scientists are spending billions of dollars on the "Large Hadron Collider (LHC) in Europe is a necessary evil. Such billions of dollars are actually the required costs to acquire more knowledge about the created universe. But, ordinary knowledge puffs. It is only divine knowledge backed up by Faith in the Savior of the universe that is the antidote to prideful knowledge.
The earthsky.org says that "the most significant discovery to come from the LHC so far is the discovery of the Higgs boson (or the “God particle”) in 2012." Nobel Prize-winning physicist Leon Lederman referred to the Higgs boson as the "God d..n Particle." While he was intending to describe how difficult it was to detect the particle, he did not realize that he was 100% correct in the naming. This discovered elementary particle (otherwise named the Higgs boson or the "God particle") proves that the particle force energy primarily originates from God.
Without God, there is no primary particle force energy which can give rise to the "big bang" theory. God is that "invisible, universe-wide field that gave mass to all matter right after the Big Bang, forcing particles to coalesce into stars, planets, and everything else," according to Peter Higgs and Francois Englert (1964). God also caused the Big Bang.
