True or false? objects that are sitting still have kinetic energy

Physics

alekssr [168]3 years ago
5 0

Kinetic energy is the energy of an object due to its motion. An object sitting still isn't moving, therefore it has no kinetic energy. The statement in the question is false.

please help i really need this for a good grade!!!!! The Large Hadron Collider (LHC) in Europe is a large device that has spent
FrozenT [24]

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.

Naya [18.7K]

Answer:

Explanation:

1.) Q=MC_v\delta T\\=\rho \times v \times C_v \times \delta T\\=1.2 \times 7 \times 7 \times 3 \times 720 \times (324-295)\\=3683232J

2.) COP

= \frac{Q_{abs}}{W}=3.88\\\\work=949286.6J

3.) Rate of heat absorption

   COP\times Power\\

=3.88\times 1010watt=3918.8watt

Therefore, cooling in minutes=\frac{\frac{3683232}{3918.8}}{60}=15.66mins

COP cannot cycle= \frac{295}{324-295}\\\\=10.17=\frac{Q_{abs}}{power}

Rate of heat absorption =(1010\times 10.17)watt=10271.7min

cooling time in minutes with cannot cycle=\frac{\frac{3683232}{10271.7}}{60}=5.98mins
