Can an objects mechanical energy be equal to its gravitational potential energy

1 answer:

8 0

If an object falls, it gives up its gravitational potential energy. The gravitational force does work on it, and speeds it up. Its GPE is converted into kinetic energy. In the absence of friction, or any external force, the mechanical energy in a system is conserved.

Is a 4p S 4s transition allowed in sodium? If so, what is its wavelength? If not, why not? b. Is a 3d S 4s transition allowed in

VLD [36.1K]

Answer:

a) 4p ⇒ 4s transition is Allowed

b) 3d ⇒ 4s transition not allowed

Explanation:

a) 4p ⇒ 4s transition

This transition is allowed because for a 4p state; l = 1 and for a 4s state I = 0

hence Δl = 1 - 0 = 1

Energy of 4p ( Ei ) = 3.75eV

Energy of 4s ( E2 ) = 3.19 eV

where : λ = 1240 eV nm / ( E₂ - E₁ )

= 2214 nm ≈ 2.214 μm

b) 3d ⇒ 4s transition

This transition is not allowed

a 3d state , l = 2 while for 4s state l = 0

hence Δl = 2 - 0 = 2

therefore the transition is not allowed
