<h2>Answer:</h2>

<u>The logistics growth model </u><u>is a realistic representation of population growth</u>

<h2>Explanation:</h2>

Environmental scientists use two models to describe populations growth over the passage of time.

The exponential growth model
The logistic growth model

Logistic population growth occurs when the growth rate decreases as the population reaches carrying capacity. We already know that carrying capacity is the maximum number of individuals in a population that the environment can support. So whenever the population approaches carrying capacity, its growth rate will start to slow. Logistic growth model is represented by mathematical equations therefore it is more realistic model.

Answer:

The distance that you marginally able to discern that there are two headlights rather than a single light source is 6.084 km

Explanation:

Given:

d = distance = 0.679 m

λ = wavelength of the light = 537 nm = 537x10⁻⁹m

dp = pupil diameter = 4.81 mm = 0.00481 m

Question: What distance, in kilometers, are you marginally able to discern that there are two headlights rather than a single light source, dx = ?

For the separation of the peak from the central maximum it is:

$sin\theta =\frac{\lambda }{d_{p} } =\frac{537x10^{-9} }{0.00481} =1.116x10^{-4}$

In this case, the two small sources of the headlights have the same angle as the images that form inside the eye

$d_{x} =\frac{d}{sin\theta } =\frac{0.679}{1.116x10^{-4} } =6.084x10^{3} m=6.084km$

Its important please answer

Yuri [45]

Answer: Well we see that v= u- ft/m

lets say that ft= feet and m= mass

so you divide those and subtract u

leaving you with the value of v which is 13

Solve for the length of the inclined plane if the angle equals 19.45 degrees.

mel-nik [20]

The length of the inclined plane is approximately 12 ft

The situation forms a right angle triangle.

<h3>Right triangle</h3>

Right triangle have one of its angle as 90 degrees.

Therefore,

The length of the inclined plane is the hypotenuse of the triangle. The length of the inclined plane can be found using trigonometric ratios.

height = 4 ft

angle(∅) = 19.45°

sin 19.45 = 4 / h

h = 4 / 0.33298412235

h = 12.0125847796

h = 12 ft

Therefore, the length of the inclined plane is approximately 12 ft

If planet i is 30.3 million miles farther from the sun than planet ii, then planet iii is 24.6 million miles farther from the s

kkurt [141]

Since the total distance for all three of the planets is 196.2 million miles, you would add planet i and planet iii, then subtract that number from 196.2

planet i and planet iii equaled 54.9 million miles, that subtracted from 196.2 equals 141.3

So your answer is 141.3 million miles

Brownian motion cannot be detected in colloids. True or false?

miskamm [114]

<span>Brownian motion is the random movement of colloidal particles suspended in a fluid. It is caused by random collisions of the molecules in the fluid medium. The particles in the solution or colloids are in constant random movement. A colloid has properties boundary to a homogenous and heterogeneous mixture. However in Brownian movement, the larger the size of a particle, the lesser its motion and the smaller the size of the particle, the higher is motion. Colloids in general have larger particle size and therefore it Brownian motion is sluggish. The statement is false.</span>
