Describe how the fermi level changes with donor level, temperature and contact with p and n type semiconductors

The force needed to overcome static friction is usually less than that needed to overcome kinetic friction.true or false?

Determine the moment of the force f about an axis extending between a and c. express the result as a cartesian vector. a is at the origin, c is at (4,3,0) and f = (4i + 12j -3k) lb coming out of b (4,3,-2).
