answer for Q4 (b)(iv) the Dooplers effect is around 3 o'clock, if you do 9/4 you get 2.25T which if you mark on the graph gives frequency thats on the equilibrium line, meaning that its around 3 or 9 oclock, but as we kow the highest frequency means the source was at 12 o'clock, we make our Y mark at 3 o'clock.
hi can you explain me one thing? isn’t the highest frequency heard by the observer when the vehicle is closest to the observer? so the closest position is 3 oclock, so why have we put the X mark on 12 oclock?

@@sasha13050 look at the arrow, it shows the DIRECTION of the car.
@@timothy8842ohhhh okay i get it now. Thankyou
sir in question b) iv) how did it the Y became in bottom of the circle ? can you explain as 9t/4 gives 2.25 t which has frequency of 1.2
he did it wrong lmao
He is a loser lol
sir, in question 1, can't we give the answers for percentage uncertainties to two significant figures?
We can depends on the data sf
sir too manay burgers in your class
in q2 b(ii) part can we just take the area of two triangles and add them?
Please reply
Yes you can but it will be twice the effort
On number 3b part 3 why did you half (1/2)
Power gets multiplied
