how was physics p22?

[kaka g]

Love, A* is not possible as it is. The highest grade in AS Level is A

And, I will hopefully get a B. Praying to the mighty God, cos if not, then I might as well be dead.

My bad Good luck.......

guyzz in calculatin speed how was the wavelength 1.5 m
i took it 80 mm
guyzz to get 90 plus as a overall physicsz marks in AS level how much we r supposed to get in P2?

I am sorry to say this but i saw a lot of answers agreed here are the wrong ones..The waves on string are progressive because the question itself says it travels from left to right and stationary waves do not travel..and the distance PQ is indeed 0.19 m because area under f-x graph gives workdone..or the other way round you should always take the average force since the force is not constant.

Back at ya <3

To make it clear, the wave one was progressive! It didnt become stationary yet.

I'm putting my set of answers.

Q1. Kelvin and ampere(rest of the part was to prove E and C SI base units)
Q2. 240m. :/
Q3. distance PQ 0.18 (but i made a blunde here i took velocity as 3.5 instead of 2.5, so the correct answer is 0.09) Would i be getting any ecf marks?? :/
Q4. torque was 19 Nm (i guess)
Q5. amplitude 40mm, speed 7.5 ms, progressive and tranverse
Q6. current 6,14 A amd Power 1474W (correct power was 40W )
Q7. no numericals.

BTW people, what were your graph's shape (parabolic or opp??)

I, for one, couldn't ever remember the content of a paper
