Why the spectral lines are narrow lines?
Why are spectral lines narrow? Because the emitted photon must carry away the energy lost by the radiator. Except for tiny "recoil energy" this is the difference between the upper and lower energy levels of the well isolated emitting atom, for narrow lines. If the atom is not part of a very rarefied gas, then other "near by" atoms interacting even weakly with it cause, especially the upper level of an outer shell excited electron, to have slightly different energy levels, so measurements of the wave lengths, which require many photons, have an observed spread or line width. Even if the source is a very rarefied gas so the energy levels are not slightly shifted by other atoms, there is still a finite "natural width" to the line. This is caused by the uncertainty principle. I. e. unless the period in which the emission occurs is large, the photon energy can not be precise. - Billy T.

What is the measure of the kinetic energy of the atoms of an object?
Kinetic energy is the energy created by the motion of an object. In classical mechanics, kinetic energy is calculated using the equation: KE = 1/2 * m * v^2 (where KE = kinetic energy, m = mass, v = velocity) Potential energy is energy that an object has simply due to its position and configuration. This energy can be caused by where it is in a force field. The most common potential energy is gravitational potential energy. There is also electrical, magnetic, and elastic potential energy. In classical mechanics, gravitational potential energy created by the Earth is calculated using: PE = mgh (where PE = potential energy, m = mass, g = acceleration due to gravity, h = height of the object)
Why is kinetic energy denoted T?
'T' usually denotes temperature. In thermal physics, temperature is a measure of the kinetic energy of particles as they move around inside the substance.I can't think of any other explanation, as the letter 'T' is not really linked with kinetic energy in any other situation.

What happens when an electron moves from the excited state to the ground state?
when an electron moves from excited state to ground state it emits photons of wavelength equal to the difference between the two energy levels. Consider a hydrogen atom. If the electron is at the second energy level in the atom (the energy of this level is -3.4 eV )it can stay there for about only 10^-8 s and then after that it just to the level below .If it jumps from second to ground state (energy of ground state is -13.6 eV) it emits aphoton of energy = 13.6-3.4 =10.2 eV. .............................Gho$t
In terms of the Bohr theory of the hydrogen atom what process is occurring when excited hydrogen atoms emit radiant energy of certain wavelengths and only those wavelengths?
"Electrons move from a lower energy level (ground state) to a higher energy level only after the electron absorbs a specific quantum of energy. The electron releases that energy moving from a higher to a lower energy level releasing a photon of light. An electron can only absorb and emit certain quanta of energy, and cannot be located in between energy levels."Taken from: http://www.google.com/url?sa=t&source=web&ct=res&cd=3&ved=0CBIQFjAC&url=http%3A%2F%2Fsp.rpcs.org%2Ffaculty%2FMillerD%2FChemistryH%2FHomework%2520Answers%2FEMSpectrumWS7%2520Answers.doc&ei=QFrbStfHNI2OMfO3-NYH&usg=AFQjCNHkbOVlZ8CR1IdFcCh8XK_zkZpFsA&sig2=hNCznJIXMkP8R4apk0H4tA
What does t in atom mean for chem?
The word "atom" is not an acronym. The letter 't' in the word does not mean anything in particular.

A physical property that tells you how hot or cold matter is. The average speed of the particle in a substance?
The average translational kinetic energy of a monotomic atom is directly proportional to the thermodynamic temperature of the atom. E=1.5 (kT) where k = the Boltzman Constant where T = The Thermodynamic Temperature in Kelvin since it is the average kinetic energy is applied... 0.5mv2 = 1.5kT T = (mv2)/3k where m is the mass of the atom and v is the speed of the particle. Thus, the thermodynamic temperature is proportional to the square of the velocity.

Is unit impulse an energy signal or power signal?
checking if it is an energy signal E= integration from 0 to infinity of t gives infinity so it is not an energy signal P=limit ( t tending to infinity)*(1/t)*(integration from 0 to t/2 of t) gives us infinity so it is not an energy or a power signal
What are the lyrics for hold your breath?
One minute we were up, we were up, we were on a roll Next time we couldn,t take it, deal, we,re in danger now That night I was wrong, I couldn,t get it under control I know I gotta hold my breath, I don,t wanna, gotta hold my breath Next day I wonder but I wasn,t sure If I would feel this way next week when I heard no more (heard no more) Didn,t really want talk or stuff, but I wanted to doubt What did you think I,m gonna save my breath, because you,re breathing on someone else Okay you got my now, you heard the news, you blocked me out, you cut me loose I high in love, but you let me down, and there,s no coming back to me Yeah, did you know there,s no fear in love If you think I,m coming back, don,t hold your breath What you did to me oh yeah I can,t forget If you think I,m coming back, don,t hold your breath (what,d you say, what,d you say) Don,t hold your breath (what,d you say, what,d you say) Don,t hold your breath (what,d you say, what,d you say) Don,t hold your breath (what,d you say, what,d you say) Don,t hold your breath It,s been a week, still moping around in the same old flow Each time I come up for air with no where to go Every since you been on the high road, I,ve been feeling so low I know I gotta hold my breath, because you,re breathing on someone else Okay you got my now, you heard the news, you blocked me out, you cut me loose I high in love, but you let me down, and there,s no coming back to me Yeah, did you know there,s no fear in love If you think I,m coming back, don,t hold your breath What you did to me oh yeah I can,t forget If you think I,m coming back, don,t hold your breath (what,d you say, what,d you say) Don,t hold your breath (what,d you say, what,d you say) Don,t hold your breath (what,d you say, what,d you say) Don,t hold your breath (what,d you say, what,d you say) Don,t hold your breath Don,t be cruel, because I would never be that cruel to you, so don,t Don,t be foolish, because if you were so good to me then we wouldn,t have to go through this, so don,t So don,t be cruel, because I would never that cruel to you, so don,t Don,t be foolish, because if you were so good to me then we wouldn,t have to go through this, so don,t Yeah, you can,t touch me now, there,s no fear in love If you think I,m coming back, don,t hold breath What you did to me oh yeah I can,t forget If you think I,m coming back, don,t hold your breath Don,t hold your breath (what,d you say, what,d you say) Don,t hold your breath (what,d you say, what,d you say) Don,t hold your breath (what,d you say, what,d you say) Don,t hold your breath
