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

00:06

brought to you by ignoring forces We tried ignoring gravity

00:10

once And well it didn't work out so well in

00:13

which situation can electromagnetic strong and weak forces be ignored

00:19

And here are potential answers All right Like them all

00:25

right Well the four fundamental forces are the strong force

00:29

the weak force thie electromagnetic force and gravitational force right

00:36

We've learned that we've memorized it We chanted in our

00:39

sleep And the force works on different scales The strong

00:46

force binds nuclear ons to form atoms and the weak

00:50

force is responsible for radioactive decay Well these forces act

00:55

at a subatomic level If we're dealing with particles larger

00:58

than the size of atoms or distance is larger than

01:01

one fifteenth of a meter Well then these forces won't

01:04

apply when a nucleus undergoes beta decay is an answer

01:08

c that's the weak force in action so that's not

01:11

correct answer And when to nuclear ens moved toward each

01:14

other at a low speed while that's a result of

01:16

electromagnetic force at a subatomic level There's just not enough

01:20

mass for gravity to exert much of an influence The

01:24

answer is out too well His light travel through space

01:27

It can be affected by gravity But light is an

01:30

example of an electromagnetic wave so we can't exactly ignore

01:34

the electromagnetic force when it comes to light Answer d

01:37

is wrong too That means the correct answer is b

01:40

when we're dealing with objects of this size the strong

01:43

and weak forces definitely don't fly and electromagnetism wouldn't apply

01:49

either since both jupiter and its moons are neutrally charged

01:53

plus it would take a huge amount of electromagnetism The

01:55

influence something is largest moon much less huber The things

01:59

that beast moon's orbit planets because they're influenced by the

02:02

planet's gravity all the other forces can be a pretty

02:05

much ignored At least they could be ignored for this

02:08

question saying But remember just because you ignore a fundamental 00:02:11.25 --> [endTime] force doesn't mean that it ignores you
