3. The equation of motion of a SHM oscillator is x=0.5msin(2πf)t, where x is in meter and t is in seconds. If the position of the oscillator is at x=0.25m and t=0.25s . what is the frequency of the oscillator ?  ​

The desk has a weight of 75 lb and a center of gravity at g. determine the initial acceleration of a desk when the man applies enough force f to overcome the static friction at a and b. also, find the vertical reactions on each of the two legs at a and at b. the coefficients of static and kinetic friction at a and b are ms = 0.5 and mk = 0.2, respectively

Which process is represented by the pv diagram? a. the isobaric process b. the isovolumetric process c. the isothermal process d. the adiabatic process
