Find the wavelength of the radiation emitted when a hydrogen atom makes a transition from the n = 5 to the n = 2 state.
(in nm)-The total energy of the nth orbit of a hydrogen atom is given by:
E_n
A space probe with a rest mass of 8.3×107 kgand a speed of 0.49c smashes into an asteroid at rest and becomes embedded within it. If the speed of the probe-asteroid system is 0.27c after the collision
Yep basically what type of light source would be the most dangerous near explosive gas?-Im interpreting this question as what type of light would be dangerous in the presence of a combustible gas and
When approaching the speed of light, distances are shortened due to length contraction, so if you are travelling at the speed of light wouldnt that make all distances shrink tonothing? meaning that yo
After some long calculations, I found that the linear acceleration of a cylinder on an inclined plane (attached to a block over a pulley on another inclined plane) was 8.76238 m/s^2.How do I find the
Has something to do with heat or energy, I just forgot what the terms mean.-Actually it should read dQ = CM dT; where dQ is the change (flow) in heat energy, C is the heat coefficient for the mass M i
So I had a science today on Optics. There was a question that I did not understand. In fact, nobody understood it because the teacher did not teach us it. It is about the index of refraction and the c
By what length does a .5 mile steel iron rail stretch if its temperature were to go from -40 degrees Fahrenheit to 100 degrees Fahrenheit?-stretch is not the word, expand is.
∆L/L = α∆T, α is linear
Hi can someone please help me out on this...
if someone is conducting a double slit experiment and on the screen it forms interference fringe patterns, why would we calculate 10 fringes instead of one
determine the frequency of a photon whose energy is 3.00*10^-19 joule
________*10^14 Hz-The energy of a photon is
E = hf
where h is 6.63 x 10^-34 J*s
Therefore the frequency is f = E/h
f = (3.00 x
Guillaume puts a bottle of a soft drink in a refrigerator and leaves it there until its temperature has dropped 15.4 K. What is the magnitude of its temperature change = 15.4 K in degrees Celsius?

a simple choice of A or B would cause 2 parallel realities but few choices are that simple and can be done in very different ways. For example cereal or toast, cereal the milk could spill in an infini
A pulsar is a collapsed, rotating star that sends out a narrow beam of radiation, like the light from a lighthouse. With each revolution, we see a brief, intense pulse of radiation from the pulsar. Su
An ordinary candle lights for 4 hours and it costs $0,30. How much we pay for a 20watts light bulbs working for 4 hours ?-A 20W bulb consumes 20*4 = 80 Watt-hours of energy in 4 hours.
The unit of el
