A 0.06-kg mass vibrates according to the equation x = 0.45cos6.40t, where x is in meter and t is in seconds. Determine (a) the amplitude, (b) the frequency, (c) the total energy, and (d) the kinetic energy and potential energies when x-0.30 m.

Science and technology are interdependent. advances in one lead to advances in the other. give an example of this phenomenon.

What is the measurement of how fast an object moves relative to a reference point?

The atoms in a nickel crystal vibrate as harmonic oscillators with an angular frequency of 2.3 × 1013 rad/s. the mass of a nickel atom is 9.75 × 10-26 kg. what is the difference in energy between adjacent vibrational energy levels of nickel? (h = 6.626 × 10-34 j • s, , 1 ev = 1.60 × 10-19 j)
