Q1. A toy of mass 0.155 kg is undergoing SHM on the end of a horizontal spring with forces constant 305 N/m. When object is a distance 1.20×10-2 m from its equilibrium position, it is observed to have the speed of 0.255 m/s.

Q2. A spherical source radiates sound uniformly in all directions. At the distance of 13 m, the sound intensity level is 82 dB. What power is radiated through this source?
