Simon, a physics student, has an idea. He wants to build a device that will let him see around corners. He suggests that if he places a diffraction grating at a corner it would bend the light towards his eyes and he could see the light coming from around the corner. Using evidence from these videos, state why you think this would or would not be possible, and what the limitations of this are. Also, if he's going to place something at the corner anyway, would there be a better device to use than a diffraction grating

energy can be converted from one form to another, but it cannot be created or destroyed in ordinary chemical or physical means. do not understand what you are asking but hope this

float.

archimedes' principle

denser than water sinks in water.

denser than mercury would sink in it

when jerome paddle in flowing river towards east the net speed of jerome will increase

so the net speed of jerome will be given as

now the speed of paul will be same as it is given as he is running on the ground

so

so here we can say since the speed of jerome is more so he will win the race

now as we know the distance so the time difference is given as

so jerome will reach first and the time difference will be 203.55 s or 3.4 min
