I am pretty sure the first one was about longitudinal waves...no?


No it’s transverse
how did people do the plane displacement because i measured both lines but apparently you were meant to measure the like direct distance so almost like a hypotenuse. dk if that makes sense but i got something like 12.5 x 70

I think 6 should be constant velocity as the question specified it was in a straight line


I put constant velocity too as it has direction

U just measure the distance between the points and multiply by 70 it was 7.1 x 70 = 497

Yes it was curved

for the pressure one with F=m/a. Did u not have to work out the total surface area so 6(0.12*0.12)*1200

No because it asked for the pressure of one face. Not all of the cube is exerting pressure so just the bottom face
