20ms ?

The total T

The total T

I am not getting you.

 

[Ahmed Aqdam]

Umm umm I cant make out! it must be correct

The time period of the stationary wave is 20ms. After 5 ms, it would be a straight horizontal line, drawn on the dotted line. Take a look at this animation and you will understand the logic

The Time period you mentioned here

I am not getting you.

He means.. The Time Period.!
Look Brother : T=1/F.. F is given tin the question which is 50Hz
So T=1/50=0.02 S .. which is Equivalent to 2o ms!!

Need help please. what are up and down quarks??

LOL! I was confused what he is asking, LOL!
Dafuq !

 

[Mohammed salik]

UP Quark Hasa charge of 2/3 e.. And down Quark has charge of -(negative) 1/3e..
So in a neutron there are 2 down quarks and One up quark!

As level ?

Where is the frequency given?

 

[Mohammed salik]

Pata Nahi.. I Just Knew it !

 

[Mohammed salik]

READ THE QUESTION.. under the wave its given Bro!

Where is the frequency given? Sorry but I cant get it

 

[princeali97]

Thankyou so much!! <3

No problem.<3

 

[Ahmed Aqdam]

READ THE QUESTION.. under the wave its given Bro!

Its only given for the transverse wave which is 15 Hz

 

[Mohammed salik]

Its only given for the transverse wave which is 15 Hz

I think u r confused .. Which Question are You talking about.. Plz post the link!

Question 5 (b) can some one please show the drawing ?

Thought blocker I'm sorry if I'm bothering u a lot !
Thank u

Bhai it clearly mentions 0.25 t= 1/4 T! ?
And This is similar question to Another one.. which had the exact same thing!

Thanks! Now I get it
