Answer:
the nucleus is the center of the atom, made up of protons and neutrons, without the nucleus you'd just have a bunch of electrons floating around; the nucleus is positively charged
protons are the positively charged particles that sit within the nucleus
neutrons are particles of no charge that sit within the nucleus, and because they have no charge, they do not cancel out the positive charge of the protons, making the nucleus positive
electrons are negatively charged particles that float around the nucleus in an area known as the electron cloud, they orbit around the nucleus because they are attracted to the positive charge of the nucleus (caused by the protons), with charges, opposites attract
Explanation:
Quantum is deemed to be a distinct container with energy kept in, whereas photon is considered as an elementary particle. Photon and quantum are two very significant principles talked about in modern physics. These principles are broadly used in quantum chemistry, quantum physics, electromagnetic theory, particle physics, optics, etc. These principles are also applied in a lot of actual world applications such as high resolution microscopy, LASERs, measurements of molecular distances, photochemistry, and quantum cryptography. It is highly important to have knowledge and a good understanding in photon and quantum so that we could excel in the aforesaid fields. A photon is an elementary particle, however, a quantum is not an elementary particle. A quantum does not have the properties of both wave like and particle like, but a photon does. A photon is not about a measure of quantity and can be defined as a quantum of energy, on the contrary, a quantum can be described as a measure of quantity.
Heat applied to reactant causes a faster chemical reaction. Heat is considered as ACTIVATION ENERGY.
Activation energy is the minimum amount of energy which reactants must possess in order to undergo a chemical reaction. When heat is applied to a particular set of reactants, the heat increases the kinetic energy of the reacting particles, thus enabling them to move around more rapidly. This increases the rate of collision among the reacting particles and empower the reacting particles to overcome the energy barriers and to form the products.
Answer:
The correct answer is C) insulator
Explanation:
The characteristics of metals consist of conductivity (for example of heat), malleability (deformation property) and ductility (stretching capacity).
The horizontal distance represents wavelength λ. The time represents the period of the wave T.
Wave speed is given by v= λ/T
Hence, those are the only parameters needed.
Note: the vertical distance is for calculating amplitude which is not used in calculating wave speed.
