Answer:
The charge on the dust particle is 
Explanation:
From the question we are told that
The length is 
The width is 
The charge is 
The mass suspended in mid-air is 
Generally the electric field on the carpet is mathematically represented as
Where 
is the permittivity of free space with value 
substituting values
Generally the electric force keeping the dust particle on the air equal to the force of gravity acting on the particles
=> 
=> 
=> 
=>
Explanation:
If the displacement of an object is proportional to the square of the time taken then the body is moving with uniformly accelerated motion as it will follow Newton's second equation of motion for a particular initial velocity, which can be given by, s=ut+21at2.

Infrared light
it is also found under the name IR lights. although it’s technically invisible, it can still be seen with machinery up to at least 1050 nm in experiments.
Given data:
* The extension of the steel wire is 0.3 mm.
* The length of the wire is 4 m.
* The area of cross section of wire is,
* The young modulus of the steel is,
Solution:
The young modulus of the steel in terms of the force and extension is,
where F is the force acting on the steel wire,, l is the original length of the wire, dl is the extension of the wire, and A is the area,
Substituting the known values,
Thus, the force which produce the extension of 0.3 mm of the steel wire is 31.5 N.
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.
