Why can beta particles pass through materials more easily than alpha particles? (2 points)

beta particles are made of pure energy.

beta particles are smaller.

beta particles are not charged.

beta particles move more slowly.

Beta particles are smaller.

Explanation:

When an unstable nuclei will break into stable nuclei then the nucleus energy of the unstable nuclei will be given to the the fast moving beta particles.

These beta particles are same as electron as they are negatively charged whose magnitude of charge is same as that of electrons charge.

so we have

now since electrons are smaller in size as we compare it with alpha particles so we can say that the beta particles can penetrate to more depth then the alpha particles

so here correct answer would be

Beta particles are smaller.

electromagnetic shielding is the practice of reducing the electromagnetic field in a space by blocking the field with barriers made of conductive or magnetic materials. shielding is typically applied to enclosures to isolate electrical devices from their surroundings, and to cables to isolate wires from the environment through which the cable runs. electromagnetic shielding that blocks radio frequency electromagnetic radiation is also known as rf shielding.

the shielding can reduce the coupling of radio waves, electromagnetic fields and electrostatic fields. a conductive enclosure used to block electrostatic fields is also known as a faraday cage. the amount of reduction depends very much upon the material used, its thickness, the size of the shielded volume and the frequency of the fields of interest and the size, shape and orientation of apertures in a shield to an incident electromagnetic
