mobility or DoF of a statically indeterminate structure is always less than zero and also we can have negative value of mobility.
for checking this
we have to see the Gruebler's criterion , wher
D.F= 3(Movable link - 1) - 2*(number of Single D.F of kinematic pair) - ( number of two DF of kinetic pair)
therefore, according to definition of satatically indeterminate structure have zero movable link . hence D.F will be either zero or negative.

Explain statically indeterminate structure?
The structures which cannot be solved by the equilibrium equation are known as indeterminate structures.
What are advantages of statically indeterminate structures in construction?
they can redistribute the load and have greater moment capacity
How do you determine redundant forces in a statically indeterminate structure?
Redundant forces are chosen so that the structure is stable and statically determinate when you remove these forces. So, if you have two degrees of indeterminancy, you will have to remove two forces, remove three for three degrees, and so forth. Redundant forces are usually found when you have reaction forces AND a displacement, as it is obvious one caused the other. So when you remove these forces, the displacements are still there, and the structure has not changed, except that it is now statically determinant, and you can use method of superposition to figure out all your unknowns :)

Which has greater mobility in intrinsic semiconductor Electrons or holes?
The mobility of electrons is always greater than holes. Only the number of electrons and holes would be same in an intrinsic semiconductor.

Why use Statically indeterminate structures?
Statically indeterminate structures allow for more efficient use of materials and can accommodate larger loads compared to statically determinate structures. They also provide more stability and allow for more creative and innovative designs in engineering and architecture.
What is a statically indeterminate beam?
If you can solve the beam reactions by the equations of equilibrium, then it is statically deterrminate. If not, that is, more unknown reactions than the equations of equilibrium, then it is indeterminate, and you need to know something about its deformation to solve the reactions.

What is the difference between statically determinate and indeterminate beam?
Determinate structures are analysed just by the use of basic equilibrium equations. By this analysis, the unknown reactions are found for the further determination of stresses. Redundant or indeterminate structures are not capable of being analysed by mere use of basic equilibrium equations. Along with the basic equilibrium equations, some extra conditions are required to be used like compatibility conditions of deformations etc to get the unknown reactions for drawing bending moment and shear force diagrams.Example of determinate structures are: simply supported beams, cantilever beams, single and double overhanging beams, three hinged arches, etc.Examples of indeterminate structures are: fixed beams, continuous beams, fixed arches, two hinged arches, portals, multistoried frames, etc.
When solving for truss forces why is it important to know that the structure is statically determinate?
it isn't at all!
What is a redundant force?
redundant forces are the extra forces in a structure whose removal from a structure makes it statically determinate.for ex:in a structure of indeterminancy =2 ,2 forces can be removed
