Why the effective mass of an electron is different than it mass in vacuum?
Because you touch yourself at night.
What is the difference between inertia and mass?
The difference between inertia and mass is that inertia is the resistance to move. And mass is the amount of matter that something is made of.
The rest mass energy of an electron positron pair is?
Twice the mass of the electron, since the positron has the same mass of the electron. Or the equivalent, in energy units.An electron has a mass or energy of 511 keV.
Effective mass of holes?
Very large usually but it ranges a lot from between the mass of the moon to 100,000 or more mass of the sun.
What is the difference between gross mass net mass?
you bad person you bad person
What is electron effective mass?
it is the mass of an electron in the presence of an electric or magnetic field.
What is the difference between mass of hydrogen and mass of electron?
There are different isotopes of hydrogen. Assuming you mean the difference in atomic mass between a proton and an electron though, the atomic mass of a proton is about 1836 times greater (approx 1.007 amu), and the neutron is a little more than that (approx 1.009 amu).
What is the difference between a photon and an electron?
charge mass, Whether or not two can exist at the same place.
.: Calculate the potential difference between two plates when they are separated by a distance of a 0.005m and are able to hold an electron motionless between them. (Mass of electron = 9.1x10–31 Kg)?

Which has more mass electron or hole?
Holes have a slightly larger effective mass. I couldn't tell you what that is exactly, but the mass of an electron is:9.1094 * 10^-31 kg
Is difference of mass number is calculated by electron microscope?
no, the mass spectrometer.
What is the difference between protons and electrons?
A proton is positive and an electron is negative Protons are approximately 1,835 times the mass of the electron. Protons are in the nucleus. Electrons are in the 'shells'.
Why the effective mass of an electron is different than it mass in vacuum?
Because you touch yourself at night.
What is the difference in mass of Na ion and Na atom?
The difference in mass between a sodium atom and a sodium ion (supposing Na+) is 9.10938188 × 10-31kg (the mass of an electron). This is due to the sodium atom losing an electron to form an ion. In order to attain the mass of a single sodium atom you need to divide the molar massn (mass number) of sodium by avogadro's number. You can then find the mass of the ion by subtracting the mass of an electron from the mass of a sodium atom.
What is the difference between isobar and isotope?
isobars are elements with same mass numbers (Atomic Mass) and different atomic number (number of proton or electron)
Why effective mass of electron is negative at the top of valence band?
Because of holes
What is the difference between Aston's mass spectrograph and Dempster's mass spectrometer?
what is difference between mass spectrograph and mass spectrum
