Answer:
The work done by gravity is 
Explanation:
The data given in the question is :
Mass is 
Height from ground is 
As we know , the work done is state function , it depends on initial and final position not on the path followed.
So, work done by gravity = change in potential energy
Work done = Initial potential energy - final potential energy
Insert values from question
Work done = 
Work done = 
So, work done = 
Hence the work done by gravity is
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.
Answer:
D) not swim in or drink the water from the stream
Explanation:
Low pH means the water is acidic which is harmful to your skin as it can cause burns and irritations. So any means of contacting with water is not healthy. The damage to the skin happens as in acidic water it has more H+ than in the neutral water and the extra H+ ions can ionize the atoms which are combined to form different compounds in the skin when in contact.
Answer:
It is a example of physical change
