33.8 correct answers The sum of 9.6 and 24.231 is 33.831 . What is this sum expressed in correct
significant digits ?
first law of motion correct answers What law states that the velocity of an object does not change
unless the object is acted upon by an external force ?
Charles's law correct answers What law states that if the pressure of a gas is constant , the gas's
volume and temperature are directly proportional ?
potential energy correct answers What is energy associated with the position of an object and the
forces acting upon it ?
conduction correct answers What is the general term for the process by which heat flows through
materials and between objects in direct contact ?
amplitude correct answers What is the maximum distance that particles are displaced by a wave ?
intensity correct answers What is the strength of a sound wave ?
white correct answers What is perceived when all colors of visible light are mixed ?
gamma rays correct answers What consists of extremely high - frequency electromagnetic waves
produced by reactions in the nucleus of an atom ?
iridescence correct answers What is the phenomenon in which an object's colors are produced by
interference and depend on the viewing angle ?
, time and length correct answers According to Einstein's general theory of relativity , what
quantities are affected by gravity ?
law of electric force correct answers What law states that the strength of the attraction or
repulsion between two charged objects is directly related to the strength of the charges and
inversely related to the square of the distance between them ?
diamagnetic correct answers What is the term for a substance with no unpaired electrons ?
fluorescent lamp correct answers What type of lamp produces light by passing an electric current
through a long tube filled with a low - pressure mixture of mercury vapor and argon ?
transformer correct answers What is a device that increases or decreases the voltage of
alternating current using electromagnetic induction ?
diode correct answers What is a simple vacuum tube that uses a negatively charged filament and
a positively charged plate to allow current flow in only one direction ?
catalyst correct answers What is a substance that alters the rate of a chemical reaction without
being permanently changed or consumed in the reaction ?
precipitate correct answers What is an insoluble substance that forms ( falls out ) during a
chemical reaction ?
Lewis structure correct answers Which of the following is a diagram showing the locations of all
the atoms and valence electrons in a molecule ?
parallel correct answers A type of circuit arrangement with current divided among its separate
branches is a ( n ) ___ ? ___ circuit .
