Sound Waves and the Eardrum
While a pressure wave reaches the ear and a series of high and low pressure regions impinge upon the eardrum. An arrival of a compression or high pressure region pushes the eardrum inward; the arrival of low pressure regions serves to pull the eardrum outward. The continuous arrival of high and low pressure regions sets the eardrum within vibrational motion. This is depicted within the animation below.
Net force acting on particle of mass 2 kg is 10N in north direction.At t=o, particle was moving eastwards with 10m/s. Find displacement and velocity of particle after 2 seconds.
