Equations

Question 1

Bio A = I/M

Answer 1

Actual size = image size X magnification

Question 2

Chem mole = Ar/Mr

Answer 2

Mole = relative atomic mass / relative formula mass

Question 3

Chem Percentage yield = (actual No. mol / expected No. mol” X (100%)

Answer 3

100% - e.g 50g CaCO3 produces:

(111/100) x 50

Question 4

Phy v = f x λ

Answer 4

v = wave speed/velocity
f = frequency
λ= wave length

Question 5

Phy f = 1/t

Answer 5

f = frequency
t = time

Question 6

Phy μ = m/l

Answer 6

μ = per unit length
m = mass
l = length

Question 7

Phy v = √(T/μ)

Answer 7

v = speed/velocity
T = tension
μ = unit per length
