In Bohr’s model, angular momentum is quantized: Ln = nh. The change in an gular momentum between orbits is simply the difference in their quantized values.
The angular momentum is given by:
\( L = \frac{nh}{2\pi} \)
Where:
Substitute \( n = 1 \):
\[ L_1 = \frac{1 \cdot h}{2\pi} = L \]
Substitute \( n = 2 \):
\[ L_2 = \frac{2 \cdot h}{2\pi} = 2L \]
The change in angular momentum is:
\[ \Delta L = L_2 - L_1 = 2L - L = L \]
The change in angular momentum is \( \Delta L = L. \)
Electrolysis of 600 mL aqueous solution of NaCl for 5 min changes the pH of the solution to 12. The current in Amperes used for the given electrolysis is ….. (Nearest integer).
If the system of equations \[ x + 2y - 3z = 2, \quad 2x + \lambda y + 5z = 5, \quad 14x + 3y + \mu z = 33 \] has infinitely many solutions, then \( \lambda + \mu \) is equal to:}
