If |r|<1, the infinite sum S = a1-r. If |r|>=1 the infinite GP does not settle to a finite school sum (except the special a=0). A recurring decimal is a…
Orbital motion occurs when gravity provides the centripetal acceleration required for an object to continually fall around a massive body.
There are three types of cofactors: 1. Inorganic ions 2. Organic molecules (coenzymes) 3. Prosthetic group 1. Inorganic Ions…
Classical combustion is limited to C/H/O formula work. Modern IR finds functional groups; UV-Vis finds conjugation/colour centres; NMR maps hydrogen…
Inflammatory Response: The inflammatory response is a major component of the non-specific defence. Any damage to tissue triggers this response.…
Phospholipids: Phospholipids are derived from phosphatidic acid. A phospholipid is formed when phosphatidic acid combines with one of four organic…
Acid Strength: The degree to which different Brønsted acids give off protons (donate H+). · Base Strength: The degree to which different…
x^2 - 5x + 6 = (x-2)(x-3). x^2 + x - 6 = (x+3)(x-2). Find two numbers that multiply to c and add to b.
The textbook identifies several types of cyber-attacks: 1. DDoS (Distributed Denial of Service) Attack Definition: A DDoS attack is when many infected…
The relative strengths of weak acids are compared by their pKa values. The smaller the pKa value, the stronger the acid. The pKa value of an…
Coding schemes are standards that computers use to convert and represent data in a format they can understand, such as binary digits (1's and 0's). Since…
Cis-trans: two different groups on each C of C=C. But-2-ene yes; 2-methylbut-2-ene maybe not if one carbon has two methyls. Markovnikov: in HX addition to an…
Bacteria are useful as recyclers of nature, and they have also ecological as well as economic importance. They play essential roles in nutrient…
Acid Rain: Acid rain is defined as rain having a pH less than 5. In simple words: Acid rain is rain that is more acidic than normal because it…
D.c. flows in one direction; a.c. reverses periodically.
Urine formation is the process by which the nephron filters blood, reabsorbs useful substances, and secretes waste products to produce urine. Urea is the…
The adrenal glands are two small, triangle-shaped endocrine glands that rest on the top of each kidney. Each adrenal gland has two parts: the adrenal…
Shielding effect is the reduction in force of attraction between the nucleus and the valence electrons by the electrons present in the inner…
Nuclear fusion is the joining of light nuclei to form a heavier nucleus, releasing energy.
The determinant is a single number attached to a square matrix. 2x2: det [[a,b],[c,d]] = ad-bc. 3x3: expand along a row or column using cofactors. Cofactor…
Computing Innovation: Computing innovation means creating and using new or better computer stuff like processes, technologies, systems, and software. This…
Usually n=1: plug in and check a number identity. If the claim starts at n=2, start there. A failed base kills the proof even if the step looks pretty.
The main idea is that the hydroxyl group (-OH) on the benzene ring of phenol has a profound effect on its chemical reactivity. The lone pair of electrons…
The neuron is the structural and functional unit of the nervous system. Neurons are long, thin, delicate cells that carry electrical signals (nerve…
