you can't. Do the ones on xtremepapers , refer to the marking schemes + read examiner reports.
That's as close you get to solved papers on the internet!

Oh man this is detail to the limit PHEW !
first the fusion reaction occurs in the sun as two hydrogen isotopes combine and form a helium atom resulting in energy being released due to loss in mass this energy travels to us in the form of electromagnetic waves like ultraviolet,infra red and visible light,this is called solar energy this solar energy results in heating of the earths surface ! As earth is surrounded by water or land and both have unequal heat absorption rate a convectional current is set up.the land heats up faster and air there becomes less dense and rises as molecules gain the heat energy from the solar energy and move further apart,now at the sea the it heats up slowly so air from there travels to land where a low pressure area has been created and wind blows from the sea to the land !

Just concentrate on the energy conversion it shud be Nuclear of sun - Solar - heat - wind and describe these conversions ! i hope u get it !

Has anyone got past papers for november 1983 in biology. please I need it stat!

Why? they should be in classified biology, unfortunately , i dont have them for bio.you can study mathematical subjects from so old past papers but i dont recommend that anyone should prepare science subjects from so long ago past papers, the syllabus have changed tremendously and the paper pattern as well.

It's just a homework I got from school.

divide the wave length by frequency and u will get the time taken by the spot to cross the screen
the wave length is 1.5 and the frequency is 0.5, the result is 3 seconds
