All of the orbitals in a given subshell have the same value of the quantum number

magnetic spin

Explanation:

the magnetic spin quantum number i.e + 1/2 or-1/2 ...those are all the orbitals in agiven shell simolarly contains it

principal

Explanation:

The quantum numbers that are used in the identification of an electron are n, l, m, and s.

n= principle quantum number

l= azimuthal quantum number

m= magnetic quantum number

s= spin quantum number

All the orbitals in a given subshell have the same value of n(principle quantum number) and l( azimuthal quantum number).

first let us lay out the formula for potential

and kinetic energy:

pe = mgh

ke = (mv^2)/2

where: m=mass, v=velocity, g=gravitational

acceleration, h=height

calculating for mass using the known values of

pe:

340j = m (9.81 m/s^2) (50ft) (1m/3.28ft)

m = 2.27 kg

the law of conservation of energy states that

energy is neither created nor destroyed. therefore, the change in kinetic

energy from 50 ft to 35 ft would be equal to the change in potential energy

from 50 ft to 35 ft. however it would be opposite in signs since one is losing

while other is gaining.

ke(35ft) – ke(50ft) = - [ pe(35ft) – pe(50ft]

ke(50ft) = 0 since the brick is initially at rest

ke(35ft) = 340j - 2.27kg (9.81 m/s^2) (35ft)

(1m/3.28 ft)

ke(35ft)

= 102.38 j
