<span> You need to use this formula to solve this exercise: P(t)=Ae^(k.t)
P(t) is the p</span><span>opulation of bacteria
A is the number of bacteria at the beginning of the experiment: 71
K is the growth rate
20 min= 1/3 hours
P(0)=71
P(1/3)= 71 ⇔ P= 71 x 2 ⇔142
142= 71 x e^k/3
2= </span><span>e^k/3
ln 2 = k/3
3ln 2=k
ln(2³)=k
</span>k=ln8
Answer:
When two plates come together, it is known as a convergent boundary. The impact of the colliding plates can cause the edges of one or both plates to buckle up into a mountain ranges or one of the plates may bend down into a deep seafloor trench. ... Two plates sliding past each other forms a transform plate boundary.
