Answer:
if you are asking for static friction the answer is <u>372N</u>
Explanation
friction static=normal force x coefficient of static friction
and normal force is equal to weight of a body
so static friction = 600N x 0.62= 372N
Answer:
Inertia! I hope this helps!
Answer:
E₁ = 1.042 eV
E₄₋₃= 7.29 eV
E₄₋₂= 12.50 eV
E₄₋₁= 15.63 eV
E₃₋₂= 5.21eV
E₃₋₁= 8.34eV
E₂₋₁= 3.13eV
Explanation:
The energy in an infinite square-well potential is giving by:
<em>where, h: Planck constant = 6.62x10⁻³⁴J.s, n: is the energy state, m: mass of the electron and L: widht of the square-well potential </em>
<u>The energy of the electron in the ground state, </u><u>n = 1</u><u>, is: </u>
The photon energies that are emitted as the electron jumps to the ground state is the difference between the states:

Have a nice day!
It's C i believe. To solve it we just take 20 and divide it by 2. Which gives us the average of 10 m/s
