Physics 9702 Paper 33 -Expectations, Queries and Doubts.
well, i guess a question from oscillation (or scale balance and change in angle) with graph and one from electricity. ps. can somebody draw the graph or guide with the scale marking for m/j 2012(d) and what did you get for q# 1(c) just some rough values so i could compare them with mine? Thank you. -

definitely, yes. it will be just like (G) but lagging behind the shown path that is due to the presence of air resistance in the opposite direction which reduces the speed. -
Physics: Post your doubts here!
Since the air resistance is negligible, with greater horizontal speed the new path will lead ahead but it must obey the parabolic motion. i have attached an image, hope it helps. -

increase of wavelength decreases the brightness. Reducing the slit separation, a therefore results in the increase in the width of fringes. making each of the double slits narrower, increases the brightness and the width of fringes is unchanged. -

the speed 5.0*10^8 is the horizontal speed of the electron and in (d) we calculated from the vertical displacement after the acceleration of 2.4*10^15, the initial velocity used here is vertical which is zero. -

Question#2 (a) 1. Sum of all the force's acting on the body must be zero. 2. Sum of moment of torque must be zero i.e sum of clockwise moment = sum of anti-clockwise moment. (b) (i) Force's with equal magnitude represented by the side of the triangle and the arrow used is for the direction, head... -

For Question#5(a)(i) Use the data under the linear region of the graph, for stress/10^8 each block (2.5-2.0)/10 is of 0.05 so (0.05*3) + 2.0*10^8 (because 2.15 on the graph is the last point which cover's the linear region) i.e 2.1*10^8. For strain, take the same point of 2.15*10^8 of stress as... -

for the last part, consider the stretching of parallel springs by that single spring (it would be hard compared to the previous springs). Recall the definition that i previously wrote about spring constant and then relate that with this condition. it's pretty easy, a single spring takes a lot of... -
Physics: Post your doubts here!
You should know that a spring constant ‘k’ is a measure of how stiff the spring is. A spring that is very hard to stretch out has a large spring constant. A spring that is easy to stretch has a small spring constant. As the term spring constant implies, the spring constant is always the same for... -
Warning for those with Redspot 1000 MCQs books for Bio, Phy or Chemistry!
Ahaha! this is what i have been telling everyone too, but NO! some people just don't listen -_- -

Insha'Allah, so how much have you covered? -
✔--Physics P2: Post your doubts here --✔
i don't thinkso, see what i have observed so far is that its not the past papers or revising the syllabus that is going to get us to that level but how we manage to solve the problems with elaborating and managing the knowledge that we have. in that case, we need to get into the depth of our... -

uhm, okay so i have done the past papers from 2001 to 2010 once and doing it again, and have revised the syllabus twice as well. the problem is i haven't done the papers of 2011-2012. would that cost me? and have i done enough? and yeah, i am scared :R -
Physics: Post your doubts here!
since you haven't mentioned the question number and as i had a look there's only Q#5 which has a part iii of (b). So, if that is what you are asking for then here it is. it says clearly, (for time t=1.0sec) and in terms of A. 1. the displacement due to wave T1 alone = put your finger on t=1.0...
