what makes you think that?I guess it’ll be something from magnetism!

Its usually 3 but its always stated at the front page of the the exam under instructions. Also for some questions they specify how many significant figuresAnyone can tell me the s.fs of paper 2?? 2 or 3 s.fs? ;( and good luck on your tmr's exam!

Got it. if the previous question is "show that~", should I use that value in the question or the value I calculated in more s.f ?In the final answer you should use the same number of sigfigs as the value with the smallest number of sigfigs in your calculation.
Example:
m = 1.90 kg (3sf)
v = 2.3 ms^-1 (2sf)
The kinetic energy here should have 2sf.
Either one worksGot it. if the previous question is "show that~", should I use that value in the question or the value I calculated in more s.f ?
There is constant acceleration so v changes at a constant rate of 9.81m/s²How does vertical velocity of projectile change with time if theres no air resistance?
means its should be a straight line thru origin right?There is constant acceleration so v changes at a constant rate of 9.81m/s²
Yesmeans its should be a straight line thru origin right?
It depends on the data given. For example, all the values you work with are to two sf so you put your answers to 2 sf. Then again, sometimes they tell you to how many sf your data must be given in.Anyone can tell me the s.fs of paper 2?? 2 or 3 s.fs? ;( and good luck on your tmr's exam!
Acceleration is always 9.81 ms-1. Horizontally, there is no change but vertically, if your velocity increases uniformly when there is no air resistance because acceleration is always 9.81 ms-1How does vertical velocity of projectile change with time if theres no air resistance?
Cant depend because Feb 18 chem 22 and may june 18 22 both excluded partial pressure/conc. QuestionQ If the P5 question in march 2018 came from youngs modulus and the waves section it means that these topics won't be repeated in tommorows exam?
Drawing the diagram itself has 1 mark. Including any additional details within the diagram gives you more points.how many marks is the diagram worth in Q1 for paper 52?
1 onlyhow many marks is the diagram worth in Q1 for paper 52?
anyone reply to this postAny predictions for physics p5 tmrw?
