⩥ IR absorption for C≡N. Answer: 2250
⩥ IR absorption for C=C. Answer: 1600
⩥ IR absorption for sp³ C-H (alkane). Answer: 2850-2950
⩥ IR absorption for sp² C-H (alkene/aromatic) Answer: 3000-3100
⩥ sp C-H (terminal alkyne) Answer: 3300
⩥ if you don't have displacement Answer: vf =vi +at
⩥ if you don't have vf Answer: x= xi + vi(t) +1/2at^2
⩥ if you don't have time Answer: v^2= vi +2a(xf-xi)
, ⩥ acceleration equals Answer: change in v/t
⩥ Fnet = Answer: ma
⩥ fk= Answer: ukFn (uk given, Fn = mg or if on incline mgcosθ)
⩥ Fg= Answer: weight, mg, pVg (density x volume x gravity)
⩥ Torque = Answer: rFsinθ (r = distance from pivot, F = applied force
perp to gravity usually)
⩥ sin theta 90 (perp) Answer: 1 (torque would be max)
⩥ sin theta 0 or 180 (parallel) Answer: 0
⩥ density = Answer: m/v
⩥ effeciency = Answer: W out/W in
⩥ mechanical advantage = Answer: F out/F in
