Given the wave function: y(x, t) = 5sin27(0.2x - 3t); (x = meters, t = sec.): what are the amplitude, frequency, wavelength, angular frequency and phase velocity of the wave? in which direction is it traveling? (note: this wave is not a light wave traveling in a vacuum so va = 3 x 108 is not valid)

The dissociation energy of a molecule is the energy required tobreak apart the molecule into its separate atoms. the dissociationenergy for a particular molecule is 5.48 x 10-18 j.suppose that this energy is provided by a single photon. determinethe (a) wavelength and (b) frequency of the photon

In a load, the load is paralel to the shaft. n a. angular n b. thrust n c radial n d. none of the above

Asolid round steel rod 6.25 mm in diameter and 375 mm long is rigidly bonded to the end of solid square brass rod 25 mm on a side and 300 mm long. the geometric axes of the bare are along the same line. an axial tensile force of 5.4 kn is applied at the extreme ends of the assembly. for steel e = 200 gpa and for brass e = 90 gpa. determine the total elongation for the assembly.
