2. ### Physics question?

photon's energy E = hc/λ = 6.626e-34kg·m²/s * 3e8m/s / 1090e-9m E = 1.82e-19 J = 1.140 eV After absorbing this, the electron's energy is (-1.512 + 1.140) eV = -0.372 eV

3. ### Physics question ?

shortest wavelength means highest frequency and therefore highest energy. E = 13.6eV * (1/n² - 1/m²) This is maximized when the parenthetical value is 1, which is when an electron at level 1 is...

7. ### chem practice?

You can find the energy of the emitted photon with E = hc / λ I get E = 1.93-18 J = 12.1 eV Then by Rydberg E = 13.6eV * (1/1² - 1/n²) Set them equal and solve for n. I get n = 3 If...

10. ### physics experts?

3.11×10^9  (even if it were correct) loses you a mark for ‘missing unit’. (a) The centripetal and resultant force are the same thing in this situation, so we just need to find the centripetal force: F = mv²/r = 9.11*10^-31 * (2.29*10^6)² / (5.23*10^-11) . .= 9.13*10^-8 N...
