Nuclear radiation and radioactive tracers can be used in medicine for diagnosis, imaging and treatment under controlled professional conditions. A PET…
Limestone buildings, lakes, metals. AQI colours if the book has them. Stay indoors slogan, masks as a public slogan not a medical device lecture. Cut emissions…
One of the main aims of physics is to develop a clear and testable understanding of the physical universe. Physicists ask questions such as: • How do objects…
An organ is a structure composed of two or more types of tissues that work together to perform a specific function. Most organs contain all four tissue types.…
Vector quantities (or simply vectors) are physical quantities that require both a numerical magnitude (size) with a proper unit and a direction for…
Scientific notation writes a number as A x 10^n, where A is the mantissa and 1 <= A < 10. n is an integer. 1.7 x 10^0 is allowed, because A still sits in that…
Inert, litter, microplastics named (water chapter). Recycle slogan, less single-use slogan. Incineration named as a waste option with pollution slogans — not…
Write all y terms with dy and x terms with dx, integrate both sides, then solve if required.
Assistive Technologies (AT) refer to a wide range of tools, devices, software, or equipment designed to help individuals with disabilities or functional…
Temperature is the measure of the degree of hotness or coldness of a substance. It is directly proportional to the average kinetic energy of the particles…
Logos, report title, source period, author, generation date, and confidentiality labels provide context.
The cell potential (Ecell) for a galvanic cell is literally the potential of the cell to do work on its surroundings by driving an electric…
A good sequence uses small fresh samples, controls interference, and confirms an ion with more than one observation.
Science, technology, and engineering do not work alone. In every real-life situation, they combine: · Science helps us understand the underlying…
NMR uses magnetic properties of certain nuclei (e.g. 1H). Spinning charged nuclei act as tiny magnets. In an external field they align in quantised…
Subtract 0.5 from each lower limit and add 0.5 to each upper limit when classes are whole numbers that skip (1-10 then 11-20). That 0.5 step is how you close…
A vibrating tuning fork is held above the open end of a glass tube whose lower end is closed by water. Lowering the water changes the air-column length. At…
Template CATG -> GTAC on the other DNA strand. For RNA transcript, T becomes A and A becomes U. Diameter uniform because A-T and G-C pairs fit. Template strand…
Volatility of the halogens is how readily X₂ enters the vapour phase. Down Group 17, London forces between larger molecules strengthen, boiling points rise,…
To divide, multiply top and bottom by the conjugate of the bottom: (zw) = z w-bar / |w|2. The multiplicative inverse is z-1 = z-bar / |z|2 when z != 0.…
Internet of Things (IoT) is a network of physical devices — such as smartphones, smart watches, smart security systems, smart home appliances, smart TVs,…
SN1: one species in the slow step (the haloalkane ionises to a carbocation + X-). Then Nu grabs the cation fast. Favoured by tertiary (cation stabilised) and…
Reliable information refers to data, facts, or knowledge that can be trusted and depended upon for accuracy and credibility. It is typically obtained through…
