Fill in the word that completes each statement. Building up electric charges on a Van de Graaff generator is an example of static . Lightning is an example of static .

The correct answers are electricity and discharge

Explanation:

Van de Graaff generator is an electrostatic generator. It is used for producing high voltage static electricity. It consists of a hollow metal sphere. The charges is accumulated on it from continuous motion of the belt which is made of an insulating material.

Due to polarization, the charges builds up on an object. Van de Graaf generator is an example of static charge.

Static discharge occurs when the built-up charges flow from the object. Lightning is an example of static discharge. Lightning occurs when the clouds having an opposite charges collide each other.

Therefore, building up electric charges on a Van de Graaff generator is an example of static electricity. Lightening is an example of static discharge.

they it depends on if one believes about radioactivity, they make a geiger counter beep but maybe it was going to beep anyway electronics do wierd things all the time or it was programmed to beep near certain metals.

it takes on an electronical energy
