Praxis 5435 Latest Update 100% Correct absorption this occurs when waves pass through objects. The amplitude of a wave decreases as it passes through a medium acceleration the rate at which the velocity of an object changes over time. This will change if speed, direction, or both change. accuracy how close the measured values are to the true or actual value alkanes a type of hydrocarbon in which all carbon-carbon bonds are single bonds alkenes have at least one carbon-carbon double bond alpha decay in this type of decay, the nucleus ejects two protons and two neutrons. The particle is symbolized a Helium atom alpha particles high-energy particles that decrease the number of protons and neutrons in the nucleus by two each alternating current the charges continually "alternate" or reverse directions ammeters these are galvanometers that are calibrated to measure electric current or amperes amorphous solid has no regular or repeating arrangement of particles, has definite volume, and does not need a container to maintain its shape ampere unit for current amplitude the maximum distance of oscillation from the resting point, midpoint, or equilibrium level of a wave to its peak or trough angular momentum this describes the rotation of an object Antoine Lavoisier this person discovered the law of conservation of mass Archimedes' principle this states that an object immersed in a fluid is buoyed up by a force equal to the weight of the fluid it dispenses atomic number identifies atoms by representing the number of protons in an atom atomic size of an atom is dependent on the number of electrons and their proton balance. Decreases moving left to right across a period, and increases moving down a group atoms these are the smallest parts of an element that retains the properties of that element; they are made of protons, neutrons, and electrons Avogadro's number the number of particles defined in a mole, equal to 6.02 X 10 ^23 base units what SI is built upon. These define the unit absolutely and do not require referencing other units. These are then combined
