Explanation:
Some examples of colorful light emissions are street lights, neon signs and, of course, fireworks. Neon signs emit light when an electric current passes through the neon gas.
These are called resistors.
Answer:
Methane
Explanation:
Alkanes have the molecular formula of "CnH2n+2" which means for every carbon molecule there are two hydrogens plus two more. For example when there is one Carbon there are four hydrogens, this molecule is known as "Methane"
<u>Answer:</u> The speed of the electron is
<u>Explanation:</u>
To calculate the speed of electron for given wavelength, we use the equation given by De-Broglie's, which is:
where,
= De-Broglie's wavelength =
h = Planck's constant =
m = mass of the electron =
v = speed of the electron = ?
Putting values in above equation, we get:
Hence, the speed of the electron is
