If the velocity of the solar wind is about 400 km/s and the visible tail of a comet is 10 to the power of 8 km

how long does it take an atom to travel from the nucleus to the end of the visible tail?

Water Motor runs on water fuel free energy overunity

www.overunity.com This motor, designed and built by Dieter Marfurt, runs for weeks just on 1 Liter of water. It is based on a very special Osmosis effect and the help of gravity like a Besslerwheel and can be scaled up. Only a bit of water is needed to run this motor for weeks without refilling or refueling. The weights are shifted at the wet side and thus it produces an imbalance and begins to turn. This motor can be easily built via the sold template kit with which you can print out the structure on paper and use a scissoir to cut out the parts and assemble it. It is a great kit to study this gravity wheel and later make a scaled up version, which could power your mobile phone battery charger or other low power devices… Many thanks to Dieter Marfurt for making this kit available !

why are energy levels assigned negative values?

I am refering to Bohr’s theroem of hydrogen. He used a formula involving the “Rydberg constant”. My question is why are energy levels assigned negative values is it because the negative sign says that the energy is giving off to the surroundings? or is it because the negative sign signifying that the energy of the electron in the atom is lower than the energy of a free electron? Thanks for helping

Can Anyone Check My Chemistry HW?

Q.) In a future hydrogen-fuel economy, the cheapest source of H2 will certainly be water. it takes 467kJ to produce 1 mol of H atoms from water. what is the frequency, wavelength, and minimum energy of a photon that can free an H atom from water?

V=E/h–>> { (467kJ)(10^3J/1KJ) (mol/6.022×10^23) / (6.626×10^-34) }
E=7.75×10^-19
V=1.17×10^15

Lamda=hc/E–>> { (6.626×10^-34J) (3.00×10^8) / (7.75×10^-19) }
Lamda=2.56×10^-7

So is this right?
