Does electrical curents flows of charges across the membrane and the depolarization continues also due to charges that reject each other and the flow continues .so there appears a magnetic field as well
So, physical properties are what we can detect with our basic 5 senses or measuring tools, and the things that, when changed, dont actually change the chemical properties (like atoms and molecules). Lets take wood for an example: its brown, its solid, it can be big or small, it has a taste and smell, its boiling, freezing or melting point...
Chemical properties, on the other hand, are the things we can change with, for example, experiments and tools. Does it burn? Can it rust/oxidize? How does it react with other chemicals? Is it radioactive, or toxic? All of these are chemical properties you can probably answer.
Answer:
Yes
Explanation:
p = momentum of photon
E = energy of photon
c = velocity of light
Units of p = kg m /s
Units of E = kg m^2 / s^2
Units of E / p = {kg m^2 / s^2} / {kg m /s} = m/s
It is the unit of speed, so by the division of energy to the momentum, we get the speed. yes it is correct.
The distance between two successive crests of the wave corresponds to the wavelength of the wave, so:
8 Crests of the wave pass a given point in t=12.0 s. This means that the frequency of the wave (the number of oscillations per second) is given by
And now we can calculate the speed of the wave, which is given by the product between wavelength and frequency:
