We are currently struggling to cover the operational costs of Xtremepapers, as a result we might have to shut this website down. Please donate if we have helped you and help make a difference in other students' lives!

Thankyou!!For q. 26:
equation for doppler effect:
[Speed of sound X Frequency of source]/[Speed of sound + or - speed of source]
so just put in the values and subtract when speed of sound - speed of source (approaching) from speed of sound + speed of source (Receding) ANS= C
for q. 25
for the length of wavelength: I used d = S X T
so wavelenght = 330 X 500 X 10^-6 = 0.165 m
so a translation of 0.165m means shift the graph by 1 lambda or 2 pi or 360 degrees
so basically it will be the same graph ANS= D
hope that helps
thankyou!O
Only Ans A is correct as if wind blows, the aeroplane will move in the same direction as wind ( accelerate in that direction) and the velocity in wind will have a lower magnitude that without wind effect.
thankyouAreas under the graph (5-0.8)*20/2 + 0.8*20
thankyou!You must realise that this is a uniform block so the centre of mass is right in the center
Hope this helps
Resistance of 1st Lamp = 960 (Power = 60W)que 34 anyone ?
hey anyone please
Attention pleaseIm trying but all I get is 60655...Pa <_> SOMEONE SOLVE THIS QUESTION!!
hey anyone please
I solved it and posted it too.Attention please
use the pressure formula= density*g*depthA giant squid of length 20.0m is vertical in seawater, with the top of the squid at a depth of
8.00m. The density of seawater is 1050kgm–3.
What is the difference in pressure between the top and the bottom of the squid?
A 82000Pa B 206000Pa C 288000Pa D 389000Pa
Anyone?
nvm i got ithow do we do this????
Ohh thankyou!use the pressure formula= density*g*depth
use depth as 20m
first find the power produced by the engine itself. so using force*velocity=power hence 30000/25=1200NQ19.
Ans=C
For almost 10 years, the site XtremePapers has been trying very hard to serve its users.
However, we are now struggling to cover its operational costs due to unforeseen circumstances. If we helped you in any way, kindly contribute and be the part of this effort. No act of kindness, no matter how small, is ever wasted.
