What are two ways that scientists can study earths climate history

In positive numbers less than 1, the zeros between the decimal point and a non-zero number are blank significant

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

Match each scenario to the form of energy it represents
