... For normal mode oscillations, there is always a symmetric mode where the masses move together as if just one mass. There are three degrees of freedom in this system, and ETS is nice enough to supply the test- taker with two of them. Since the symmetric mode frequency is not listed, choose choice it! ...

Time in physics
Time in physics is defined by its measurement: time is what a clock reads. In classical, non-relativistic physics it is a scalar quantity and, like length, mass, and charge, is usually described as a fundamental quantity. Time can be combined mathematically with other physical quantities to derive other concepts such as motion, kinetic energy and time-dependent fields. Timekeeping is a complex of technological and scientific issues, and part of the foundation of recordkeeping.
