What inscribed polygon is being constructed? explain how you know.

  square, octagon, or some other polygon with a multiple of 4 sides

  (also a pentagon or decagon)

step-by-step explanation:

the circle has been divided into quarters, so we might assume the inscribed polygon will have rotational symmetry of order 4 (at least). the polygon with the least number of sides having that symmetry is a square.

the steps shown would also be first steps for constructing an octagon, or a 16-gon, or any other polygon with a number of sides that is a power of 2.

the steps shown are also first steps for constructing a pentagon or decagon. the finishing steps are somewhat more complicated, but these are the first steps.

we actually don't know the intention of the construction.

step-by-step explanation:

we can use this expression to calculate the energy gain as a particle moves with a field or the energy loss as it moves against it. (note that it is also used to define the electron-volt, a unit of energy equal to that gained by an electron as it falls through a pd of 1 v, i.e. w = 1 ev = 1.6 10-19 c 1 v = 1.6 10-19j).in fact this expression is really nothing more than the statement that potential is the potential energy per unit charge. in this case, v= w/qis simply stating that the change in potential energy(or work done) per unit charge is equal to the change in potential (or potential difference), v.student questions: uniform electric fields2electron beamcathode+5 kvanode0 v
