    For (d) calculate distance travelled by each of the trains and take the difference. Train A= 0.5bh (for the first 30s) + wb (for the next 66s) (0.5*30*20) + (66*20) =1620 m Train B= 0.5bh ( for the first 90s) + 0.5(h)(a+b) (for the next 6s)...

    so for part (b) u can equate the distance the two trains travel since they are the same. From the graph, one can see that the distance for train A is represented in a trapezium. Distance travelled= 0.5(h)(a+b)= 0.5*20*(180+120)=3000m. Train B has a triangular area under its graph...

    which subject is a better choice for oct/nov session ?

    Well for Business and Economics, there is a lot of material to study ( large volume of notes and stuff). You gotta write long essays and stuff. With accounts, you just have to understand the concepts and you are good to go (not that it will be easy) :) I would suggest Business studies cause its...

    Biology; Chemistry; Physics: Post your doubts here!

    I'd go with C. Uptake if nitrate increases with oxygen [], so that means its an energy-dependent process (active transport). Chloride ions aren't affected by the O2 [] so its reasonable to assume that its plain old diffusion.

    One observes a black colour when starch is present in the solution. Boiled amylase is denatured and won't be able to break down the starch, so u got starch still intact in the solution.

    Chemistry: Post your doubts here!

    Well i guess its cause Cl^- is smaller than I^- So fitting 7 atoms of F around a Cl atom is difficult due to a lot of repulsion between the electrons. But cause an I atom is bigger it can attach to 7 F atoms easily :)

    Mathematics: Post your doubts here!

    (1/y)*(dy/dx). Its not just (1/y) because you are differentiating with respect to x and y is a function in x.

    a little help please.:-)

    Wa alaikum assalaam :) Well my experience says that mocks are set to be way harder than the actual exams. So don't freak out if u don't do too well in them. The sciences are pretty straight-forward if u understand the concepts. For one to pass maths, practice is the key ; 8 papers/day is pretty...

    Since, after the collision the trucks are going to travel in the direction of Q, v is gonna be negative. Dividing -10MU by -5M will give you +2U.

    What Subjects should I take in A Levels?

    in the states and canada, u can't get into any med school without having another undergraduate degree (mostly 3 to 4 years). Most people do it in Physical Education and kinesiology.
