physics p12. discuss and expected gt.
The answer for that question was D, as a shorter measurement of time suggests a greater value of g -

How was Mechanics Paper 52?
Did you guys complete the paper on time? I think it was a bit lengthy, unlike M1 -
Maths M1 P42 2015 - with all answers
Wow! This means that i've got 50/50 marks *___* -
Mathematics: Post your doubts here!
In the first part we know that the block does not move, this means that the friction is 'greater than' the applied force in the horizontal direction. So the sign for "U" is 'greater than'. In the second part the block is moving so the friction is "less than" the force in the horizontal... -

We cannot divide it by two because we are dealing with vectors here. If we add or subtract vectors we have to take into account their directions too, The forces T1 and T2 have different directions so we cannot just add or subtract their magnitudes, we have to construct a vector triangle. So to... -

Don't worry, i love helping out others and doing math. I Hope you get it now! :) Btw Are you in AS Level or A2? -

Okay hmmm lets see... As we know that the system is in equilibrium, this means that the resultant of all of the forces = zero. We also know that the force exerted on the pulley by the string is 3*3^(1/2). This means that the force exerted on the string by the pulley is also 3*3^(1/2) ( because... -

Here you Go! Adding the two equal Tension vectors by the cosine rule gives the resultant which can then be used to find the Tension! -

From 0-2 seconds, both particles are travelling with the same acceleration in opposite directions. At 2 seconds the blue particle hits the ground and comes to rest, while the red particle's velocity begins to decrease due to its weight because the string has become slack. At 2.5 seconds its... -

i) In the first part you have the show the points of intersection of the two functions, cosec x = 1/sin x. So the graph of sin x can be used to draw its graph. iii b) The symmetry of the graph is used to calculate the value of B. The distance of B from the line of symmetry is the same as its... -

You can use any arbitrary value of x as the initial value, whatever initial value you use the answer will converge to 1.35.
