Sound wave causes one cup to vibrate tjis vibration (longitrfual wave progressive wave alone the string and reaches the other cup.the other cup vibrate and produucess a soumdwave at the other end

Got everything right exactly for the E=mc2 and the precaution. I forgot to square the c and I put insulate the cup for the precaution 😅

For question 4, how did you get 3.17*10^-4? I did it and got 4.75*10^-4. I'm confused here.

Gamma rays are uncharge, alpha particles positively caharge and deflected tiward the negataive downwards

Smalll junction is a able to be inserted in the blue part of the flame, response quickly rapidly changing temperatures vwry accurate they can measure vwry high temperatures

Adjusting x to reduce its resistance this will imcrease tje current in the coil
ayannalewis
Increase tje current in the coil, increase the number of turn in the coil, £=un I

Longitudurial wave, progress soundwave required a material

Excuse me sir, by chance could the gradient be 0.0884

For the graph can I just round the numbers off?

sir for the specific heat capacity, wouldn't the answer to one significant figure be 4000J?
