Where should the property "little voltage loss across long distances" be placed in a venn diagram? a) direct current b) alternating current c) both alternating and direct current d) neither alternating nor direct current

What are the applications of electromagnetic waves

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

When using the scientist method, which step comes last?
