Answer:
The initial and final states of the hydrogen atom were n=2 and n=6 respectively.
Explanation:
We must first obtain the energy of the photon;
E= hc/λ
where;
h= Plank's constant = 6.6 * 10^-34 JS
c= speed of light = 3* 10^8 m/s
λ = wavelength of light= 411 nm = 411* 10^-9 m
Substituting values;
E = 6.6 * 10^-34 * 3* 10^8 / 411* 10^-9
E = 4.8 * 10^-19 J or 3.0 eV
But ;
En = 13.6/n^2
So E = En final - En initial
3.0 = -13.6(1/n^2final - 1/n^2initial)
If we substitute n^2final = 6 and n^2 initial = 2 then the RHS becomes approximately equal to the LHS
Therefore the initial and final states of the hydrogen atom were n=2 and n=6 respectively.
Answer:
<h2>6 m/s²</h2>
Explanation:
The acceleration of an object given it's mass and the force acting on it can be found by using the formula
f is the force
m is the mass
From the question we have
We have the final answer as
<h3>6 m/s²</h3>
Hope this helps you
Answer:
through shared electrons
Explanation:
because stability of an atom is decided by the electrons.
Answer:
The balloon will go to the back of the car.
Explanation:
A balloon filled with helium is much lighter than regular air, so the surrounding air is denser. After that, it has a lot to do with the motion of air in the car. Air pressure shifts whenever you press the break or accelerate, and the balloon will move accordingly. By moving the opposite you would. Because you're heavier than air.
