Question

Instructions

In a two-page paper, research how physics is used in a specific profession of your choice. You should identify two physics principles used in the profession as well as explain, in detail, how they are used.

Answer 1

I'm a physics undergraduate so I'll tell you about 2 principles which I use

1. Time flow is unidirectional- Whatever work I'm supposed to do, I do it timely whether the work is to attend classes or to complete the reading task allotted to myself or to meet my girlfriend. As time won't flow back after the time limit is exceeded nothing can change it.

2. Reversibility of light- This is my fun time principle it tells us that if a light ray travelling from point A to point B in a certain medium follows certain path then if the light was sent from B it would travel along the same path to reach A. So while playing hide and seek the persons who's seeking for everyone says your name and you aren't able to locate him by staying on your position and looking full 360 degs then you know that he/she is bluffing .

3. My class gate's handle is broken so one needs to push it anywhere to open it, now here we already know that torque is responsible for opening the gate and 'Torque= Force*(distance between point of application of force and the rotational axis)' so in order to open the gate by applying minimum force I push it as far away from axis as I can as in this way I increase the distance hereby decreasing amount of force necessary for opening the gate.

I hope that I would have satisfied you.
