work done=446.9 J . so option (c) is correct.
Explanation:
the formula for work done is given by
W= F d
F= force= mg where m= mass and g= acceleration due to gravity
F= 3.8 (9.8)=37.24 J
so W=37.24 (12)
W=446.9 J
Ohm's law states that: 
Explanation:
Ohm's law states that in a conductor, the potential difference across the conductor is directly proportional to the current flowing through it. Mathematically,
where
V is the potential difference
I is the current
The constant of proportionality is called resistance (R), and it gives a measure of "how much the conductor opposes" to the flow of current. Therefore Ohm's law can be rewritten as
where R is the resistance. By rewriting the equation as
we see that the larger the resistance, the lower the current in the conductor.

Answer:
The effect of gravitation is more in liquid than on solid because inter molecular force of attraction is less in liquid and it is weak than that of solid. ... Whereas in solid the molecule are densely packed together an the inter molecular forces are constantly acting upon one another, this results in higher forces.
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.
