The piezoelectric effect is the production of an electric potential difference across certain materials when they are mechanically stressed or deformed.
This scientific debate considers whether research into fundamental particles should continue when scientific discoveries can create major benefits but may also…
Blue to brick red. Same tell: aldehyde oxidised to acid (carboxylate in alkali). Heat required. Combine with iodoform to pin a structure. Oxidation of aldehyde…
Potential difference between two points is the change in electric potential energy per unit charge when a charge moves between those points.
Asexual reproduction involves a single parent and produces genetically identical offspring (clones). It does not involve gametes or meiosis. The main methods…
Instantaneous speed is the speed of an object at any specific instant of time. It is the speed at a particular moment, as opposed to the average speed over…
A wave is a disturbance that transfers energy from one place to another without permanently transferring matter from source to destination.
Oxidising power falls down Group 17 because atoms get larger and more shielded, electronegativity falls, and gaining an electron becomes less favourable. So F₂…
A geometry proof is easier when you always write the same headings. Start with the statement (the claim in words). Draw a figure that matches the statement,…
Hydroelectric Power is the process of generating electricity by harnessing the energy of flowing or falling water. The gravitational potential energy of…
Computer System: A computer system comprises several core components that work together to perform various tasks. The essential components include Input…
The equations of uniformly accelerated motion describe straight-line motion with constant acceleration. The first equation relates velocity and time, the…
Nerve impulses are electrical signals that travel along neurons. They result from a difference in electrical charge across the plasma membrane of a neuron.…
A target fragment and vector are cut, joined, introduced into host cells, selected and multiplied. Screening distinguishes clones carrying the desired insert.
Transport in Plants: Transport in plants is the movement of water, minerals, and food (sugars) from one part of the plant to another through specialized…
From ab = cd, cross multiply to get ad = bc. Then expand and solve the linear equation. Example: x+13 = 42 gives 2(x+1)=12, so x+1=6 and x=5. The…
Pulmonary Circulation: The pulmonary circulation is the portion of the circulatory system that carries deoxygenated blood from the right ventricle of the…
The elements in Group 17 (or Group VII-A) are called halogens. The name halogen is derived from the Greek words: · "halous" meaning salt -…
The main idea is that the absolute potential of a single electrode cannot be measured. We can only measure the difference in potential between two…
A flame test is a qualitative test for some metal ions. A clean nichrome wire, dipped in concentrated HCl to clean it, then in the sample, is held in a roaring…
Ethene + Br2: the C=C attacks Br2, a bromonium / stepwise school picture, product 1,2-dibromoethane. Br2 water decolourises (orange to colourless) — the alkene…
Computer Software: Computer software, often referred to simply as "software," is a collection of programs, data, and instructions that tell a computer how…
The textbook explains that developing the MVP is a critical concept in product development. It involves creating the simplest version of the product that still…
Solubility Product Constant (Ksp): The product of the molar concentrations of the ions in a saturated solution of a slightly soluble ionic…
