It looks like you have missed the necessary options for us to answer this question so I had to look for it. Anyway, here is the answer generally as the ℓ quantum number increases the energy is slightly higher. As a result 2s and 2p are no longer identical in energy in atoms<span> with more than one electron.</span>
Hope my answer would be a great help for you. If you have more questions feel free to ask here at Brainly.
Answer:
A) No conclusion can be drawn without more information about the two balls.
Explanation:
Answer:
√2
Explanation:
If the final kinetic energy is 2 times the initial kinetic energy:
KE = 2 KE₀
½ mv² = 2 (½ mv₀²)
v² = 2 v₀²
v = √2 v₀
Therefore, the ratio of the final momentum to the initial momentum is:
p / p₀
mv / (mv₀)
v / v₀
√2
Answer:
The photoelectric effect is a phenomenon in which the photoelectrons are emitted from the metal when an incident electromagnetic wave hits the metal. The incident light should have a threshold frequency to meet the work function of the metal
Answer:
It is a predator.
Explanation:
They eat other insects so therefore I think they're a predator.
