Imbalance of electric charge on an object’s surface.
Seen in daily life: hair rising, balloon sticking to wall.
Proton: + charge (in nucleus)
Neutron: 0 charge (in nucleus)
Electron: – charge (orbits nucleus)
Neutral atom = equal protons & electrons
Positive = more protons
Negative = more electrons
Rubbing transfers electrons.
Based on Electrostatic
1. Rank of Matrix
Echelon Form: rank = no. of non-zero rows
Normal Form: reduce to identity matrix (I); rank = no. of 1’s on diagonal
2. Matrix Forms
Echelon Form: zeros below pivots
Normal Form (RREF): pivots = 1 and only non-zero in column
3. System of Equations
Form augmented matrix [A|B], row reduce
Consistent if no row like [0 0 0 | b≠0]
Unique: rank A = rank [A|B] = no. of vars
Infinite: rank A = rank [A|B] < no. of vars
No soln: rank A ≠ rank [A|B]
4. Linear
Regulation & Deregulation:
Regulation balances safety and cost. Deregulation in 1978 led to lower fares but also industry consolidation and labor issues. NTSB investigates incidents and recommends safety reforms.
Labor & Infrastructure: Events like the 1981 ATC strike show stress and fatigue in aviation labor. Aviation functions as critical infrastructure—yet worker conditions and support are often strained.
Passenger Rights: Emerging in the 1960s–70s consumer

STANDARD HUMAN ESSAY
Thesis: The standard human is a constructed ideal shaped by processes of statistical classification and biopolitical control. Using concepts like l’homme moyen and biopolitics, we can see how bureaucracies and infrastructures defined “normality,” excluded those who didn’t fit, and upheld systems of power that continue to regulate bodies today.
1st Body: Define l’homme moyen (Quetelet’s “average man”) as the origin of statistical norms used to model the “standard
ASL and English Simalarities and differences
Similarities Basic Grammatical structure: · ASL and English share the same grammatical structure such as subject-verb-object when making a sentence. This makes it easier for English speakers to understand what an ASL person is saying · ASL and English also have different tenses used to talk about past present and future actions · Unlike learning a new language, you don’t have to learn new verb forms that you have not seen before Facial Expressions

"Vår jord och vi människor är skapade på ett helt perfekt sätt... Detta betyder att den enda logiska slutsatsen är att intelligent skapare var delaktig. En Gud."
Här ser vi ett tydligt exempel på sammanförd syn, eftersom personen menar att vetenskapliga saker (som syretransport, matematik och kroppens funktion) egentligen redan visar att Gud finns. Det är också ett exempel på Intelligent Design, vilket betyder att man
