my tutor s*cks....like srsly.

As in your teacher or hired tutor ?

Tutors suck up your money and may/may not what they are trying to teach you. I dont trust them.

Teachers have a lackadaisical attitude and conveniently forget vital points. I dont trust them either.

Who do  trust ?? THE DISCOVERY CHANNEL !!!  QUESTION EVERYTHING !!!

Q1 bii:

Area= o.25xpiexsqaure of diameter
therefore the percentage uncertainty of area=persentage uncertainty of diameterx2

Q7b:

will be less deviated..will cross the first path, and bend beyond it with a smaller angle..

is this some kind of rule to find such uncertainities?  and what is the main formula we have to use here? and could u do question 3.
thx  :o ;D ;D ;D ;D

lol no prblm.. and YES its a rule..for example if a radius of a sphere has uncertainty of 2%, and volume =4/3 x pie x r^3, then uncertainty of volume= 2x 3= 6%..and um out now..when i go home i'll do Q.3..sorry
