Tues-Day 1
Physics - MAGNETISM UNIT EXAM is on Thursday; one day only, multiple choice questions only.
We reviewed the first 3 left-hand rules for drawing magnetic field lines (the third is actually for determining the force on a current carrying wire or on an electron);
we used a 4th rule for determining the magnetic field lines emerging from a solenoid: curl the left hand fingers in the direction of the current looping around the solenoid; your thumb then points to the north pole of the solenoid/magnet - then you draw the lines (ANTS) as usual.
We did a magnetic field lines mapping lab.
AP Chem - we discussed the relative strengths of conjugate acids and bases; we then used the meaning of their relative strengths to predict whether products or reactants are favored for a given Bronsted acid base neutralization reaction.
Equilibrium I unit exam tomorrow! Study notes, and practice problems!
