(noun)

The Egyptian universe.

Examples of Ma'at, in the following topics:

  • Ancient Egyptian Religion

    • The Egyptian universe centered on Ma'at, which has several meanings in English, including truth, justice and order.
    • Ma'at was renewed by periodic events, such as the annual Nile flood, which echoed the original creation.
    • They believed humans possessed ka, or life-force, which left the body at death.
    • However, the ba returned to the body at night, so the body must be preserved.
    • By the New Kingdom, the soul had to face dangers in the Duat before having a final judgment, called the Weighing of the Heart, where the gods compared the actions of the deceased while alive to Ma'at, to see if they were worthy.

  • Ancient Egyptian Monuments

    • It is the largest and oldest monolith statue in the world, at 241 feet long, 63 feet wide, and 66.34 feet tall.
    • The temple was the house dedicated to a particular god, and Egyptians would perform rituals there, give offerings, re-enact myths and keep order in the universe (ma'at).
    • At the front of each court was a pylon (broad, flat towers) that held flagpoles.

  • Humans and Electric Hazards

    • Electric power causes undesired heating effects whenever electric energy is converted to thermal energy at a rate faster than it can be safely dissipated.
    • Thermal energy delivered at this rate will very quickly raise the temperature of surrounding materials, melting or perhaps igniting them.
    • A person can feel at least 1 mA (rms) of AC current at 60 Hz and at least 5 mA of DC current.
    • The current may, if it is high enough, cause tissue damage or fibrillation, which leads to cardiac arrest. 60 mA of AC (rms, 60 Hz) or 300-500 mA of DC can cause fibrillation.The potential severity of the shock depends on paths through the body that the currents take.
    • Usually the best way to help the victim is to give the fist a hard blow with an insulator or to throw an insulator at the fist.

  • Two-Component Forces

    • If no net force is applied to the object along the x-axis, it will continue to move along the x-axis at a constant velocity, with no acceleration .
    • If the object is spinning, it will continue to spin at the same constant angular velocity.

  • Rotational Inertia

    • To develop the precise relationship among force, mass, radius, and angular acceleration, consider what happens if we exert a force F on a point mass m that is at a distance r from a pivot point.
    • We can rearrange this equation such that F=ma and then look for ways to relate this expression to expressions for rotational quantities.
    • We note that a=rα, and we substitute this expression into F=ma, yielding:
    • This equation is the rotational analog of Newton's second law (F=ma), where torque is analogous to force, angular acceleration is analogous to translational acceleration, and mr2 is analogous to mass (or inertia).

  • Equilibrium Constant Expression

    • The equilibrium constant is an expression that gives the ratio of reactants and products at equilibrium.
    • The law of chemical equilibrium states that, at any given temperature a chemical system reaches a state in which a particular ratio of reactant and product activities has a constant value.
    • At time = 0, the rate of the forward reaction is high and the rate of the reverse reaction is low.
    • As the reaction proceeds, the rate of the forward reaction decreases and the rate of the reverse reaction increases, until both occur at the same rate, reaching equilibrium.
    • The equilibrium constant,denoted by K, is the ratio of products to reactants at equilibrium.

  • Citizenship Rights

    • Nationalization is the acquisition of citizenship by somebody who was not a citizen of that country at the time of birth.
    • New citizens are welcomed during a naturalization ceremony in Salem, MA.
