Answer:
The correct answer to the following question will be "4.08 × 10⁻¹⁹ Joule".
Explanation:
Given:
Wavelength, λ = 486.0 nm
As we know,
On putting the estimated values, we get
⇒ 
⇒ 
∴ 1 ev = 1.6 × 10⁻¹⁹ J
Now,
Energy, 
⇒ 
<u>Answer:</u> 3 neutrons are produced in the above nuclear reaction.
<u>Explanation:</u>
In a nuclear reaction, the total mass and total atomic number remains the same.
The nuclear reaction for the fission of Americium-244 isotope follows:
<u>To calculate Y:</u>
Total mass on reactant side = total mass on product side
Hence, 3 neutrons are produced in the above nuclear reaction.
Answer:
Estuaries are often called the “nurseries of the sea”

I can help you only with what is electron in ground state.
The electron which is not excited or over which no external force is acting that could possibly make it jump to the higher state,is said to be in its ground state.In excited state,the electron has more energy than it normally has.
For convenience,suppose you are an electron,you are in Normal mood,but when your little brother snatches the Tv remote from your hand,you become angry.Your normal state is your ground state and your angry state is your excited state.
