Answer:
\Delta E=1.22\times 10^{-22}J
Explanation:
The energy of electron in any state is given by 
here h is planck's constant n is state of electron L is the infinte potential well m is the mass of electron
We know that 
Potential well dimension = 
Mass of electron 
So energy required to electron to jump from ground state to 3rd state
Answer:
The potential difference between the student and the tap causes electrons to transfer to the tap which is earthed.
Hope this helps my sis and others

sanay akoy pag padendyahan niyo nay. hahahahhahahaha maawa kayo saakin mga aking mahal hahahhahahahahhaha hahah en then go char hahahhaa
If they have the same momentum, then
m₁ v₁ = m₂ v₂
If m₁ > m₂, then we must have v₁ < v₂ to preserve the equality.
The object with the larger speed - the second object - thus has more kinetic energy.
Answer:
In a permanent magnet, the magnetic field comes from the motion of the electrons inside the material, or, more precisely, from something called the electron spin. The electron spin is a bit like the Earth spinning on its axis. The magnetic field is a vector, the same way the electric field is.
