Experimental Sciences

hey, i am also currently doing the IB and i am in DP1. i completely understand how you are feeling right now. but you should understand that everyone is in this together, and everyone goes through the same struggle as you are. you should just believe in yourself and do the best you can! Good luck and i know you can do it... just hold on and keep on working and going on with IB!!!!!! 

Which table or section in the data booklet do you use to find the enthalpy of atomization and the lattice enthalpy?? 

Draw the Ferris wheel at time t = 0, with P at the bottom. Draw another wheel, showing location of P, for t = 20 minutes. Then repeat for t = 10 minutes, and find the height of P. Finally, draw the wheel at t = 15 minutes and find the height of P.

I'm having trouble with the following question: Let P be a point on the wheel (which has a diameter of 100 m). The wheel starts with P at the lowest point, at ground level. The wheel rotates at a constant rate, in an anticlockwise (counterclockwise) direction. One revolution takes 20 minutes. What would be the height of P above ground level after 15 minutes?   Thank you 

Hey guys,  since I haven't started studying for ess exam yet ... Please guide me like how to study and what to do? or if anyone of you have notes please share if you don't mind or just tell me how should I go about studying? Thanks a lot
