LiRa [457]

Answer:

\frac{dN}{dt} = 14130

Explanation:

Logistic growth is a measure of continuous growth of a population of individuals in such an environment where the resources are limited. Such type of growth pattern has a characteristic growth curve which is S-shaped or sigmoidal.

The equation for logistic growth is as follows -

Change in population size = \frac {dN}{dt} = rN(K- \frac {N}{K})

Where,

N = size of population

r = intrinsic rate of increase

K = carrying capacity

The values of r, N and K are given in the question as 12, 30 and 40 respectively.

So,

\frac{dN}{dt} = 12 \times 30(40 - \frac{30}{40}) = 14130

If a car is traveling 100 km/h west and comes to a stop in 3 min, what is the car's acceleration?
Nataly [62]

Answer:

0.15 m/s² east

Explanation:

We can use following kinematic equation for Uniformly-Accelerated Motion to solve this problem:

<h3>v = v₀ + a × t</h3>

Where <em>v</em> is the final velocity, <em>v₀ </em>is the initial velocity, <em>a</em> is the acceleration and <em>t </em>is the time interval.

<u>The data of the problem is:</u>

  • v₀ = - 100km/h (remember to have a frame of reference, I decided traveling west will be towards the negative values and traveling east will be positive).
  • v = 0 km/h (the car comes to a full stop)
  • t = 3 min

<u>Replacing the data in the formula</u>:

0 km/h = -100 km/h + a × 3 min

It's very important to use the same units when solving problems. I will convert kilometer to meters and hour or minutes to seconds, because the answer choices are given in m/s².

  • 0 km/h = 0 m/s
  • \frac{100 \ km}{\ \ h} * \frac{1000\ m}{1\ km} * \frac{1\ \ h}{3600\ s} = \frac{27.78\ m}{\ \ \ \ s}
  • 3 min * \frac{60\ s}{1\ m} = 180 s

Then:

0 m/s = -27.78 \ m/s + a * 180 s\\+27.78 m/s = a * 180 s\\

\frac{+27.78 \ m/s}{180\ s} = a\\\\+ 0.15 m/s^2 = a

And considering our frame of reference, a positive sign indicates that the acceleration is east-bound.
