Radioactive substances are those that break down (or decay) by releasing radiation on their own. For instance, actinium, thorium, polonium, uranium, radium, etc.

The answer to this question is A because, first of all, option D can be ruled out because it states that energy is conserved, which is untrue because fission processes always release energy. Second, options B and C create the false impression that both fission fragments need to be identified. They may differ, as A illustrates.

Hazardous waste that contains radioactive material is known as radioactive waste.

It is produced by nuclear power plants, laboratories, hospitals, and other establishments.

Almost all waste is managed and contained to ensure that it doesn’t emit harmful radiation; however, some obviously require permanent and deep burial.

Radioactive wastes are not used.

D is therefore the right choice.

The amount of time it takes for an isotope’s radioactivity to decrease to half of its initial value is known as its half-life.

Alpha particles have the highest ionization power of the three common radiation types.
Alpha particles have a positive charge and are made up of two protons and two neutrons. They have strong interactions with the material’s atoms and electrons as they move through it, leading to numerous ionizations. This implies that they are able to remove electrons from atoms, producing free electrons and positively charged ions that can then produce additional ionizations.
By contrast, the ionization power of beta and gamma radiation is lower.

In a vacuum, photons travel faster than in liquid water.

Photons move at the speed of light, or roughly 299,792,458 meters per second (186,282 miles per second), in a vacuum, like space.

However, because of interactions between the photons and the medium’s atoms or molecules, light moves a little more slowly in a material medium, such as liquid water, than it does in a vacuum. Light travels at about 225,000,000 meters per second in water, which is roughly 3/4 of its speed in a vacuum.

The medium’s refractive index, which measures how much light is slowed down when it travels through a substance as opposed to a vacuum, is the cause of this speed differential.

Finding P alone will provide the answer to this question. In options where a photon is the only particle, P should be a “particle.”

P: Photon

· Q: Spontaneously

· R: Infinitely

· S: Farthest

T: The Universe This is the right sequence.

The beta particle comes from an atom’s nucleus and can be either positively charged (positrons) or negatively charged (negatrons). When an atom undergoes radioactive decay, its nucleus releases a beta particle. However, the electron lives outside of an atom’s nucleus.

The quantity of radioactive samples decreases by half with each half-life.

Life in the First Half: 400->200

Life in the second half: 200 to 100

Life in the third half: 100->50.
