Identify 4 careers that non-physicists hold that use physics every day. write a brief description of each.

there are different carers done by non physicists and lay man which are governed by the laws of  physics.one may take a simple example of a VIDEO GAME DESIGNER.

In case of a video game designer,we use HD graphics,cutting etc.that are based on physics.

another is the AUDIO DESIGNER who uses unwittingly the physics while transmitting,amplification etc.

the third one  is GYMNASTIC where we have to maintain the perfect balance ,flexibility .Moment of inertia plays a crucial role i it .A slight imbalance in moment of inertia can cause a fatal condition.It sounds very simple,but it is very complicated in its a way.There is also career in it.

the fourth one is the poker player.One has to understand the the modeling,statistics,probability etc.

diagram is missing, but i will try to explain your doubt.

answer:

amplitude is the maximum displacement or distance moved on a point of a vibrating body or wave measured from its equilibrium position.it is equal to half the length of vibration path.
