Of the three types of radioactivity characterized by rutherford, which is/are not electrically charged

Answer;

-Y- rays

Explanation;

-The three types that were discovered were classified according to their penetrative ability and electrical charge: and named alpha, beta and gamma.

-Alpha are fast moving helium atoms. They have high energy due to their large mass, they are stopped by just a few inches of air, or a piece of paper.

-Beta are fast moving electrons. They typically have energies in the range of a few hundred keV to several MeV. Since electrons are might lighter than helium atoms, they are able to penetrate further, through several feet of air, or several millimeters of plastic or less of very light metals.

-Gamma are photons, just like light, except of much higher energy, typically from several keV to several MeV. Depending on their energy, they can be stopped by a thin piece of aluminum foil, or they can penetrate several inches of lead.

i think the miocene epoch spans the time from 23 million to 12 million years ago.

[ answer ]

foliated

[ explanation ]

foliation forms in a rock when pressure squeezes the rock together. the rock then has a design of many different color little lines. there are three types of foliated rock. the types are slate, schist, and gneiss. each type of foliated rock is different based on grain size and foliation characteristics. the lines appear when the rock has been under pressure.
