Complete the following two statements regarding quantum-mechanical concepts associated with the bohr model of the atom and refinements that resulted from the wave- mechanical atomic model.
two important quantum-mechanical concepts associated with the bohr model of the atom are that eledtrons are particles moving in orbitals, and electron energy is quantized into
two important refinements resulting from the wave-mechanical atomic model are that the electron position is described in terms of a and electron energy is quantized into both shells and subshells--each electron is characterized by quantum numbers.

Aspring is used to stop a 50-kg package which is moving down a 20º incline. the spring has a constant k = 30 kn/m and is held by cables so that it is initially compressed 50 mm. knowing that the velocity of the package is 2 m/s when it is 8 m from the spring and neglecting friction, determine the maximum additional deformation of the spring in bringing the package to rest.
