Thank you. I now understand.

According to me the function shouldn't have had the factor √2/a but I now believe the factor arises upon normalising phi (x). Is that correct?

I tried writing the function as: Ѱ = c1Φ1 + C2𝚽2 + C3𝚽3 in order to then find mod C1^2... But ɸ = √2/a sin(ᴨx/a) and not sin(ᴨx/a) I cannot understand how the factor of "√2/a " comes

yes, I tried doing it too. Made it a whole lot easier and I got the answer. Thanks so much !

I haven't used latex before. I hope these images are okay

of course y and z terms are invariant but for the x and t terms I am getting an additional factor of 1/1-v^2/c^2

so I can find the centrifugal force but shouldn't the Coriolis force be 0 because the mass is at rest?

Hey... I finally got 100 too. Thanks for the help, I looked more carefully and found the error in the calculations

Solving for t' by substitution I obtained t' = 7/8. Then I substituted x= 10 and t = 7/8 in the given equation. Is that the right way to do it? My answer key says the answer is 100 but I am getting 78.5.

thanks

thanks for your help :)

If I take the vector sum, I am getting the angle to be 1. (tan^-1 tan(1)). Is that correct?

I understand now. Thank you so much :smile:

So when the source is not vibrating, it is not setting waves due to vibration? But it is moving so it is still causing disturbance in the medium ... And I happened to read that if the source is moving faster than the speed of sound, a shock wave is set up. How ?
