Thank you We sneak and here's your shmoop du jour

00:05

Brought to you by quirks what's with the weird name

00:09

Because that's just how physicists get crazy All right question

00:14

Can a cork be described as a system and hear

00:18

the potential answers going Yes yes No no where's Our

00:21

dark force All right well first of all what the

00:25

heck is a cork Well the cork is the smallest

00:27

particle that we currently know of neutrons and protons are

00:31

made of corks And as you know neutrons and protons

00:34

are pretty darn small themselves And remember a system is

00:37

a collection of objects fields and forces that influence each

00:41

other right The system also has an internal structure and

00:45

that structure determines the relationship between the objects in a

00:48

system Well since a cork is the smallest particle that

00:52

we know of it doesn't have a structure There are

00:55

no little pork lings inside the court It just is

00:58

what it is without an internal structure A core can't

01:01

be a system So our answer his options see No

01:04

it has no internal structure Courts do have mass in

01:07

the occupy space We also carry charges and interact with

01:11

other particles but none of those are defining characteristics of

01:15

the systems So answers eh and beer incorrect and answer

01:18

D is wrong too It doesn't matter if a system

01:20

is larger small in this case it's the internal structure

01:23

that matters now Maybe someday when we're hotshot particle physicists

01:27

will discover that corks are actually made of even smaller

01:31

particles But don't worry we'll name the new particles something

01:34

reasonable like the small a tron or something like that 00:01:38.411 --> [endTime] Yeah
