Scientific knowledge is both long lasting and open to change. in your own words, explain why scientific knowledge should be re-examined and re-tested from time to time. include two examples that will support your response.

The electric field between square plates of a parallel-plate capacitor has magnitude e. the potential across the plates is maintained with constant voltage by a battery as they are pulled apart to twice their original separation, which is small compared to the dimensions of the plates. the magnitude of the electric field between the plates is now equal to a)e b)e/4 c)e/2 d)4e e)2e
