Which type of radiation consists of a fast stream of negatively charged particles?
a. alpha particles
b. beta particles
c. gamma rays
d. positron particles

Correct option is B.

Explanation:

Beta particles are known as the electrons which obtains in the nucleus when a neutron divides into an electron, and a proton. The electron is emitted at a very high-speed, but the proton stays in the nucleus. Since an electron contains -1 charge, and a beta particle also contains -1 charge.

So, beta particle is known as the type of radiation which consists of a fast stream of negatively charged particles.

some think that theories become laws, but theories and laws have separate and distinct roles in the scientific method. a law is a description of an observed phenomenon in the natural world that hold true every time it is tested. it doesn't explain why something is true; it just states that it is true.

i need the answer to this too but idk it ; -;
