Abox is at rest on an inclined surface. which diagram correctly illustrates all forces, including any component forces? assume the x-axis is parallel to the surface.

If the ama of the inclined plane below is 2, calculate the ima and efficiency. ima = efficiency =

How is sound energy produced a. vibrating objects b. objects being heated c. temperature differences d. stationary objects

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)
