Answer:
The change from deep to shallow water waves occurs when the depth of the water , d , becomes less than one half of the wavelength of the wave, λ....A wave with a longer wavelength travels at higher speed . In contrast , shallow - water waves show no dispersion . Their speed is independent of their wavelength .

Answer:
from the spaces left between chains when the polymer is
formed.
Explanation:
Polyethylene polymer may be of high or low density. Whether the polymer is of high or low density depends on the arrangement of the polymer chains.
If the polymer chains are close together such that the resultant polymer is crystalline with chains packed closely, we have high density polyethylene.
On the other hand if the chains are not close together and there are spaces left between chains when the polymer is formed, then we have low density polyethylene.
Hence, low density polyethylene gets its name from the spaces left between chains when the polymer is formed.

Answer:
In an uncharged atom, the number of protons is always equal to the number of electrons. Apr 24, 2017
Explanation:
Neutron: An uncharged particle found in the nucleus of an atom.
There is only one stable atom that does not have neutrons. It is an isotope of the element hydrogen called protium. Protium, which contains a single proton and a single electron, is the simplest atom.
