If current) = 41.01A is generated by flowing of 510 electrons/cm3 via a conductor. Then the electrons through this conductor (b) have a density) =
A/m2 and
(c) are drifting at a speed of Vo =
m/s2

How to tell if a molecule is polar or nonpolar with electronegativity

Hydrogen atoms are excited by a laser to the =4n=4 state and then allowed to emit. what is the maximum number of distinct emission spectral lines (lines of different wavelengths) that can be observed from this system? 8 6 2 7 4 5 1 3 calculate the wavelength of the 4⟶14⟶1 transition. =λ=

Mechanical energy is when the amount of kinetic and potential energies added together remains the same. conserved created lost
