Explanation:
1. explain the Big Bang Theory
Ans: At its simplest, it says the universe as we know it started with an infinitely hot, infinitely dense singularity, then inflated — first at unimaginable speed, and then at a more measurable rate — over the next 13.8 billion years to the cosmos that we know today.
2. what is alpha particles
Ans: Alpha particles, also called alpha rays or alpha radiation, consist of two protons and two neutrons bound together into a particle identical to a helium-4 nucleus. They are generally produced in the process of alpha decay, but may also be produced in other ways.
3. what is Gamma radiation
Ans: A gamma ray, also known as gamma radiation (symbol γ or. ), is a penetrating form of electromagnetic radiation arising from the radioactive decay of atomic nuclei. It consists of the shortest wavelength electromagnetic waves and so imparts the highest photon energy.
4. what is beta particles
Ans: A beta particle, also called beta ray or beta radiation, is a high-energy, high-speed electron or positron emitted by the radioactive decay of an atomic nucleus during the process of beta decay. There are two forms of beta decay, β⁻ decay and β⁺ decay, which produce electrons and positrons respectively.
5. full form of HST
Ans: Harmonized Sales Tax (HST) Definition.
6. how something is made up from nothing. universe is expand explain
Ans: The universe is everything, so it isn't expanding into anything. It's just expanding. All of the galaxies in the universe are moving away from each other, and every region of space is being stretched, but there's no center they're expanding from and no outer edge to expand into anything else.
