Equations Flashcards
1
Q
A = I/M
Biology
A
Actual size = image size (or mesured size) X magnification
2
Q
mole = Ar/Mr
Chemistry
A
Mole = relative atomic mass / relative formula mass
3
Q
Percentage yield = (actual No. mol / expected No. mol” X (100%)
Chemistry
A
100% - e.g 50g CaCO3 produces:
(111/100) x 50
4
Q
v = f x λ
Physics
A
v = wave speed/velocity
f = frequency
λ= wave length
5
Q
f = 1/t
Physics
A
f = frequency
t = time
6
Q
μ = m/l
Physics
A
μ = per unit length
m = mass
l = length
7
Q
v = √(T/μ)
Physics
A
v = speed/velocity
T = tension
μ = unit per length
8
Q
1 mm –> μm
Biology
A
1 mm x 1000 = 1000 μm
1000 μm / 1000 = 1 mm
