- Question #de1b8 + Example - Socratic
Definitions of Energy vary a little by state standards And scientists aren't always very good about using terms consistently Chemists, for example, like to speak of entropy instead If you are in a state which uses the SCREAM acronym, you may have the choices: Sound, Chemical, Radiant, Electrical, Atomic, and Mechanical You could make a case for many of these so-called forms of energy
- Question #26469 - Socratic
Electric Meters usually measure in KWH units KWH is acronym for Kilo Watt Hour It's basically units of Work Energy You can do the math for the Kilo Watt Hour It's simple KWH = 1000* 60*60 Watt-Sec rArr KWH = 3 6*10^6 Watt-Sec We know that, Power = (Work) (Time) Units of Power are Watt, Work are Joules and Time are Seconds So, Watt-Sec is nothing but Joules So, KWH=3 6Mega Joules One KWH
- Solve using FOIL? (x^2+6) (x^2+3) - Socratic
then multiply the OUTER terms So, that's the first term in the first binomial, and the last one in the second binomial: #x^2 * 3 = 3x^2#

- Question #8b990 - Socratic
The acronym "OIL RIG" is used to help remember this : "Oxidation Is Loss, Reduction Is Gain" You may first have heard oxidation in relation to say, rusting of iron where we say Iron has been oxidised: "Iron" + "oxygen" to "hydrated iron (iii) oxide" Although the formation of an oxide helps make an intuitive link to iron being oxidised, we can
- How do you simplify 3^ { 4} - 24\div 4\cdot 4- \frac - Socratic
3^4-24-:4*4-54 6=color (blue)48 Simplify: 3^4-24-:4*4-54 6 This expression can be simplified by using the order of operations, which is represented by the acronym PEMDAS , which means: Parentheses (brackets) Exponents (powers) Multiplication and Division from left to right because they are equal in rank
