ODghe number of electrons needed balance
The kinetic energy of a moving object is calculated through the equation,
KE = 0.5mv²
where KE is kinetic energy, m is mass, and v is the velocity. Substituting the known values in the problem above,
KE = 0.5(55 kg)(16 m/s)²
KE = 7,040 J
Thus, the kinetic energy of the skydiver is approximately equal to 7 kJ.
Answer:
The wavelength of the line in the absorption line spectrum of hydrogen caused by transition is 657.1 nm.
Explanation:
Energy of the electron in a hydrogen atom in nth shell:


Energy of an electron in n = 2:

Energy of an electron in n = 3:

Energy difference in between both the shells:
:





=


The wavelength of the line in the absorption line spectrum of hydrogen caused by transition is 657.1 nm.
