    Can anyone explain terminal velocity to me for P2 and Electromagnets/ the motor effect for P3 please?
    Thankss
    Ok terminal velocity. Is it ok if I use the parachutist example?

    I got another question let's say I got D in the exam and my ISA is at an A what would my overall grade be? (Please be a B)
    It might be a B or even a C
    Last year in biology i got three As and a B in my ISA and a B overall

    Do you think drugs will come up as the 6 marker in B1? I really hope it doesn't because I hate that topic

    Well the 6 marker in
    2015- shoots and roots response to environmental factors
    2014- Adaptations
    2013- Carbon cycle
    2012- Adaptations

    It is possible...

    Terminal velocity: when air resistance is = to your weight, then you reach a terminal velocity. This is the highest velocity attainable by an object as it falls through air. All inaminate objects, and humans, have momentum and thus have atleast two forces acting on them. [Weight and Air Resistance] :^_^: Thus when you fall in the air, its these two forces that act on you. But which one is bigger? If your falling at a high velocity in the air, which will be bigger, air resistance or weight? Air resistance, but weight will also be acting upon you but at a lower distribution. Air resistance exists because air molecules collide into a falling body creating an upward force opposite gravity. This upward force will eventually balance the falling body's weight. Parachutes lower the terminal velocity, so its safe for you to land on the ground. If not then, :bike:

    Electromagnetic, is when you have an iron core (in appliance) and as there is a changing magnetic field in the iron core, an current/pd is induced along the ends of a secondary coil attached to a primary coil. If there was an d.c instead of a.c, no current would be changed and thus the p.d would be 0.

    Motor effect: when a wire cuts the field lines of a magnetic field, it causes a force to act on the wire. If you resemble, with flemings left hand rule you can find the direction/current etc. Its hard to explain on here but i'll leave a link below.

    Yeah pleaseee I would be sooo grateful!! Can you also give ideas about other scenarios which might link in with terminal velocity please so I can try to explain the process myself
    Also, can you explain electromagnets/motor effect after please thank you

    Don't worry. It most likely will be, but it won't be as worst as the 6 markers regarding experiments (the horrible one in last year's B2 paper). However, I found an 6 marker on drugs, with an attatched mark scheme, so it'll act as a good frame for your answer. I'll leave the link below, its Q 3.03 -

    Well if you look at the post above yours you'll see a lovely example!
    I'm happy to answer any bio or chem related questions though!

    hello,
    we were told that there would be a 10-20 min break between the two exams as the examiners have to set up the exam papers and stuff like that
    Thank you! I hope we're allowed to go outside for loo breaks, snacks and last minute revision!

    OK. had a look at last years grade boundaries and well, we could say that this year might be slightly easier. BUT DON'T TAKE ANYTHING FOR CHANCE

    Chemistry exams(c1+c2) were really easy so I think they will be harder.

    Yup chemistry C1 and C2 were 50+ for an A* Much higher than the other sciences, but C3 was 40+ for an A* :eek:

    Some people said that the Biology exam was fairly hard and grade boundaries were high, so they expect the biology exam to be easier. Other's thought the chemistry was really easy ( which I do agree) and so they would make it harder this year. But again the grade boundaries were 50/60 which is the highest I've ever seen.
    And most people said that Physics would be around about the same level of hardness lol.

    Agreed! Really, anything higher than a 52 out of 60, would be a safe A*!

    I did triple Biology last year and this year i'm doing triple chemistry and physics this year. I'm happy with physics but c2 is stressing me out so much, i did a past paper and I got an A but I have to miss out some questions as I didnt know how to them at all ( Luckily c2 is in june an dnot may.
