The perfect model structure would see theory (the AO1 knowledge) being separate from evaluation, but should also show them linked to each other effectively.

For instance, when talking about the bio...

An elastic collision is a collision where objects will bounce after they hit each other. For example balls in a pool game bounce after heating each other. For an elastic collision, Mechanical Energy Kinet...

In French, both le passé simple and l'imparfait are used for past situations. However, they are not used the same way.

Le passé simple is used for short, sudden actions such as :

1.) using the wave speed formula for an electromagnetic wave, c=fλ, (c=3.00x10^8 m/s)

f=c/λ where c=the speed of an electromagnetic wave.

f=(3.00x10^8)/(560x10^-9)= 5.36x10^14 Hz

(1.) (a.) f’(x)=3x^2+6x-2

(b.) x=6 gradient=142

(c.) since f’(x)>0 at x=6, the function is increasing.
