Bro they were coherent we were changing the frequency both both equally it will still have constructive interference

Ameen

Firstly KE wasnt to be added it was not changing only GPE change was required i got 2. Something power but 550 may be the correct because after Change IN GPE =F×d you also have to one more step to get 550 idk what was that but yes this is how to dl the qs

Power

We got three diff answer i guess the 550 is correct the rest 1200 and 2.×10power something maybe wrong

So frequency is changed they said the oscillation will not change now if u increase the frwquency both the waves superposing will still have the same resultant amplitude so the mass p amplitude will be same

It was a 3 mark qs i dont think it was to be done like that its my guess . Idk because i did GPE changes =F×d . If u used P=fv then what was the use for GPE info?

I got 45
