Which is not true of gamma radiation particles? they have no mass. they are deflected in an electric field. they accompany alpha and beta radiation. they are high energy electromagnetic waves?

They are deflected in an electric field.

Explanation:

Here we know that gamma radiations are part of electromagnetic waves with highest frequency range.

So it is the electromagnetic waves of highest energy range.

These radiations are the result of nuclear energy transitions i.e. when a new nucleus is formed due to alpha or beta decay then it is in high energy state or unstable then it comes to it ground state of stable state by losing energy in form of gamma radiations.

So gamma radiations are just like high energy photons which are mass less and charge less.

So it neither be deflected by electric field nor it has any effect due to magnetic field

explanation:

vestigial organs (like your appendix) are organs that no longer serve a purpose.

with the invention of the automobile, the woman of the house could drive to the store and get groceries. women were also free to socialize more. during world war ii women were allowed to work in factories to the war effort and could drive to work or ride mass transit buses to their jobs.
