What is the answer to this
Nerdsarecool
  • Nerdsarecool
The first seismic waves to form in an earthquake are the S waves L waves P waves Static waves
Nerdsarecool
  • Nerdsarecool
P waves right
13ziar
  • 13ziar
let me check
Nerdsarecool
  • Nerdsarecool
Ok
13ziar
  • 13ziar
yes you're right :p
Nerdsarecool
  • Nerdsarecool
Thanks
Nerdsarecool
  • Nerdsarecool
One more thing
13ziar
  • 13ziar
ok
Nerdsarecool
  • Nerdsarecool
If the number of waves passing a point each second goes up, the frequency Does not change Goes up Goes down Can go up or down
Nerdsarecool
  • Nerdsarecool
Does that mean it goes up
13ziar
  • 13ziar
im checking
Nerdsarecool
  • Nerdsarecool
Ok
tygrr321
  • tygrr321
doesnt change i think
Nerdsarecool
  • Nerdsarecool
Are you sure
tygrr321
  • tygrr321
...i think
Nerdsarecool
  • Nerdsarecool
Ok
Nerdsarecool
  • Nerdsarecool
Thank you
tygrr321
  • tygrr321
no wait
Nerdsarecool
  • Nerdsarecool
Ok
tygrr321
  • tygrr321
this is science of seismic waves right?
Nerdsarecool
  • Nerdsarecool
Yes
13ziar
  • 13ziar
is it every second the amplitude increases: http://www.bbc.co.uk/bitesize/standard/physics/telecommunications/communication_using_waves/revision/5/
Nerdsarecool
  • Nerdsarecool
So what is the answer
tygrr321
  • tygrr321
go up or down
13ziar
  • 13ziar
not 100% but i think that it doesn't change
tygrr321
  • tygrr321
go up or down
Nerdsarecool
  • Nerdsarecool
Does it change or go up or down
Nerdsarecool
  • Nerdsarecool
I am confused
tygrr321
  • tygrr321
up down
13ziar
  • 13ziar
because every second the line goes up and down so it happens every second and doesnt change
Nerdsarecool
  • Nerdsarecool
Ok but the frequency increases it does not change the wave
tygrr321
  • tygrr321
wave stay same
Nerdsarecool
  • Nerdsarecool
Ok thank you
tygrr321
  • tygrr321
frequncy change
13ziar
  • 13ziar
so staying the same means it doesnt change right?
Nerdsarecool
  • Nerdsarecool
Yes
13ziar
  • 13ziar
so is that ok?
Nerdsarecool
  • Nerdsarecool
Do any of you need some questions answered
13ziar
  • 13ziar
not now but thanks anyway if you have any ways to memorise 2 A4 pages filled with text in a day then please tell me!
Nerdsarecool
  • Nerdsarecool
Ok
13ziar
  • 13ziar
actually i have one!
Nerdsarecool
  • Nerdsarecool
What
tygrr321
  • tygrr321
ill help if i can
Nerdsarecool
  • Nerdsarecool
We will both help
tygrr321
  • tygrr321
right
Nerdsarecool
  • Nerdsarecool
What is your question
tygrr321
  • tygrr321
if u guys have instagram plz follow me
13ziar
  • 13ziar
OK thanks both of you write the formulas for: acceleration speed velocity time kinetic energy
Nerdsarecool
  • Nerdsarecool
So what is the question asking
Nerdsarecool
  • Nerdsarecool
Tell you which one is faster
tygrr321
  • tygrr321
? ? ? ? ke
Nerdsarecool
  • Nerdsarecool
Let me check
tygrr321
  • tygrr321
all i know or remember
13ziar
  • 13ziar
write the formulas of those ?
tygrr321
  • tygrr321
if u need math help look up MATHWAY
Nerdsarecool
  • Nerdsarecool
du/dt
Nerdsarecool
  • Nerdsarecool
Is acceleration
Nerdsarecool
  • Nerdsarecool
Oh
Nerdsarecool
  • Nerdsarecool
Nerdsarecool
  • Nerdsarecool
That is for acceleration
13ziar
  • 13ziar
also please explain them because i dont understand them?
Nerdsarecool
  • Nerdsarecool
Oh ok
Nerdsarecool
  • Nerdsarecool
Nerdsarecool
  • Nerdsarecool
It is kind of like algebra
Nerdsarecool
  • Nerdsarecool
Turn you letters into a fraction
Nerdsarecool
  • Nerdsarecool
And then square the number
13ziar
  • 13ziar
k work out the rest and ill read at the end if that's ok cause i am busy trying to memorise my script! :(
Nerdsarecool
  • Nerdsarecool
Ok
Nerdsarecool
  • Nerdsarecool
Than acceleration/ at
Nerdsarecool
  • Nerdsarecool
Is 1/2
13ziar
  • 13ziar
also if you can then give an example please
Nerdsarecool
  • Nerdsarecool
Then square at 1/2 and then you got it
13ziar
  • 13ziar
using the formula
Nerdsarecool
  • Nerdsarecool
The link was a picture i will send it again
Nerdsarecool
  • Nerdsarecool
13ziar
  • 13ziar
k
Nerdsarecool
  • Nerdsarecool
Press the link
Nerdsarecool
  • Nerdsarecool
I got one for speed to
Nerdsarecool
  • Nerdsarecool
13ziar
  • 13ziar
k
13ziar
  • 13ziar
isnt there any simpler ones?
Nerdsarecool
  • Nerdsarecool
No
Nerdsarecool
  • Nerdsarecool
Sry
Nerdsarecool
  • Nerdsarecool
If here were i would tell you
13ziar
  • 13ziar
k
13ziar
  • 13ziar
isnt there any simpler ones?
