Please help me with this question...

Physics

1) In first case, both the objects(hand & tea) are in direct contact, so heat will flow by the process of "Conduction" 

2) In this case, objects are not in direct contact, and heat is transferring from one to another by "Convection"

3) Here, there is no contact between the objects (our body & sun), sun light with heat comes through the process of "Radiation"

In short, Your Answers would be:
1) Conduction
2) Convection
3) Radiation

Hope this helps!

The first is conduction. 

This comes as the hot water spills on to your hand through contact.

The second is convection. The hot air rising is due to convection currents being set up.

The third is radiation. This is heat transfer through space.

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.

Can someone with an IQ score of 120 be gifted? Based on psychological thought, explain why or why not and give an example. ILL M
Pani-rosa [81]
Hello!

Yes, someone with an IQ score of 120 can be gifted. 

An IQ score of 120 means that the individual is moderately gifted. Although this IQ doesn't qualify for gifted education programs, research shows that people with IQs of about 145-180 don't perform significantly better than people with 120s IQ in terms of success.

As an example, professor Dean Simonton from the University of California found that an optimum leader should have an IQ in the 120-125 range, so having an IQ of 120 would mean that the individual is gifted for leadership.

Have a nice day!

A circular grill of diameter 0.25 m has an emissivity of 0.8. If the surface temperature is maintained at 150°C, determine the r
Schach [20]

Answer:

the required electrical power when the room air and surroundings are at 30°C.= 52.51822 Watt

Explanation:

Power required to maintain the surface temperature at 150°C from 20°C

P= εσA(T^4-t^4)

P= power in watt

ε= emissivity

A=  area of surface

T= 150°C= 423 K

t= 20°C= 303K

/sigma= 5.67×10^{-8} watt/m^2K^4

putting vales we get

= 0.8\times5.67\times10^{-8} \pi\frac{0.25^4}{4}(423^4-303^4)

P=52.51822 Watt

the required electrical power when the room air and surroundings are at 30°C.= 52.51822 Watt
