    PHYSICS PAPER 2 DISCUSSION & QUERIES

    Alpha partivle is a helium nucleus, beta particle is a fast moving electron and gamma radiation is an electromagnetic wave. Alpha have the greatest ionising power and weakest penetrative power while gamma have the opposite

    PHYSICS PAPER 2 DISCUSSION & QUERIES

    Just remember that like poles repel and unlike poles attract. Learn the experiment which asks you to draw the magnetic field lines using compasses or sprinkling iron pieces. I think that's it...the rest is about electromagnetism

    Depends on the power station. For fossil fuel/thermal : chemical to kinetic to hear to kinetic in turning turbines and finally into electrical Hydroelectric: potential into kinetic into electrical Wind: kinetic into kinetic into electrical Solar: heat into chemical into electrical Pendulum...

    Wait sorry I meant voltage not current/charges!

    It means that less charges are going to the capacitator which uses them to recharge itself. Hence more current is available for the bulb

    I think it said to form an alkaline solution...I'm sure tho. We're we supposed to know that calcium hydroxide isn't soluble o.O

    Haha no I wrote no3 instead of vo3...don't ask me why. The question was damn confusing :p

    He has sources... Oh & were the two ions nh4(+1) and VO3 (-1)?

    Yeah so the frictional force acts toward the Center of the turntable. The couns moving because of the frictional force...so to speak, it becomes the coins force. To keep the coin at the same distance from the Center if the turntable, there has to be a force on rhe coin acting toward it...to...

    Cause the resultant force, called the centripetal fotce) always acts toward the Center of acurved path...IT ONLY APPLIES TO CIRCULAR PATHS though

    How'd u figure that out? Could u check for bio as well?

    How low do u suppose the threshold for bio could fall?

    Biology Paper 22 Discussion thread.

    So for 2c we had to write about damaged blood vessels, alveoli, bronchioles etc, collapsed lungs, organs not being able to move properly, excessive mucus formation in the air passages, and all these leading to a reduction or disruption in the gaseous exchange mechanism...us that it?

    Biology Paper 22 Discussion thread.

    Yeah I did that too! I merely mentioned about alveoli, but I mostly wrote about the organs related to inspiration/expiration and how they will be affected :S how many marks was the question for?
