each resistor has resistance of 52.9 ohms right
two resistors are connected in parallel with battery and one in series
so the total resistance =(1/52.9+1/52.9)^-1+52.9
that gives total resistance 79.35 ohms
since P=V^2/R
P=230^2/79.35
=0.67kw

Ahhh thankewww !!each resistor has resistance of 52.9 ohms right

Kindly someone answer mine pleaseeeee ???http://papers.xtremepapers.com/CIE/Cambridge International A and AS Level/Physics (9702)/9702_w09_qp_22.pdf
Sorry by mistake that was copied wrong its oct/nov 2009 Q3 part b .... have attached the correct link again

Question 5 c(i) 2.
I'm getting 270 degrees..
But the answer is 135 degrees :$
Please explain.
Why do you want to know about quarks?? They aren't in the syllabus. Did you see a question on them?Need help please. what are up and down quarks??
Kindly someone answer mine pleaseeeee ???
Oooohh .. That was easyat A the phase angle is 45 at B its 180
so phase difference will be 180 -45 that is 135

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

Look at this post.but why would be a straight line after 0.005 s? please can u xplain. thnx
Gotcha! I didn't actually see the graph properly.. I was takin it as 4 blocks..Hello there, first we know that 1 Wavelength = 360 degrees, look at the graph, you'll see that 1 wavelength is 8 blocks.
Blocks between A and B are 3 blocks.
Cross multiply,
360-----> 8 blocks
?----------> 3 blocks
You'll get phase difference between A and B is 135 degrees
This is the mark scheme answer I couldn't solve itwhats the answer m getting 22.6 ;/
