The economy will never be fully employed in the future the economy will be completely unemployed because pretty soon we will invent robots that'll take our jobs
The spin quantum number (ms) describes the orientation of the spin of the electron: TRUE
The magnetic quantum number (ml) describes the size and energy associated with an orbital. An orbital is the path that an electron follows during its movement in an atom: FALSE
The angular momentum quantum number (l) describes the orientation of the orbital: FALSE
The principal quantum number (n) describes the shape of an orbital: FALSE
<u>Explanation:</u>
- The magnetic quantum number (ml) - The number of orbitals and the orientation within a subshell is determined.
- The orbital angular momentum quantum number (l) - The shape of an orbital is determined.
- The principal quantum number (n) - The energy of an electron and the distance of the electron from the nucleus is described.
The resistivity of tungsten can be determined using the empirical equation
Rw = 48.0 (1 + 4.8297 × 10^−3 T + 1.663 × 10^−6 (T^<span>2))
</span>Input the temperature to get the resistivity
For aluminum, you can look for the empirical equation for its resistivity but what is available is a graph between resistivity and temperature. Simply use the graph to determine which temperature will result to the same resistivity of tungsten at 24 C.
