A quantitative description of a system is important as it provides information about the carrying capacity of habitable worlds.

<h3>What is a quantitative description of the components of a system?</h3>

Quantitative description refers to the description of a system which is focused on the numerical value of the properties or components of the system.

For example, a quantitative description of the components of a given habitat will be focused on the number of the individual species in the habitat. It will also be focused on the numerical value of the non-living components of the system and how such values affect the living components of the system numerically.

This information will then be used by scientists to see how modifications of the various quantitative components of the habitat will help to improve the chances of survival of species found in the habitat. This leads to such concepts as the carrying capacity of a habitat which is the maximum number of species that the available resources is a habitat can easily sustain.

In conclusion, a quantitative description is important to in investigations about the habitable world.

When wile coyote is launched his velocity is 20 m/s. As a slightly underweight 10kg coyote, how far would the 400 N/m spring hav

Deffense [45]

Answer:

E = 1/2 m v^2 = 1/2 k x^2 equating KE of coyote and spring

x^2 = m v^2 / k = 10 kg * 20^2 m^2 / s^2 / 400 N / m

x^2 = 10 * 400 / 400 (kg m^3 / kg-m) = 10 m^2

x = 3.16 m

Calculate the speed of a 500.0 kilogram car that possesses 400,000 joules of kinetic energy.

lozanna [386]

Answer: 40m/s

Explanation:

Given that,

speed of car (v) = ?

Mass of car (m) = 500.0 kilogram

Kinetic energy (KE) = 400,000 joules

Recall that kinetic energy is possessed by a moving object, and it depends on the mass and speed by which the object moves

i.e Kinetic energy = 1/2mv²

400,000J = 1/2 x 500.0kg x v²

400,000J = 250.0kg x v²

v² = 400,000J / 250.0kg

v² = 1600

Find the square root of v²

v = √1600

v = 40m/s

Thus, the speed of the car is 40m/s

8. As a roller coaster car crosses the top of a 51.0-m-diameter loop-the-loop, it's apparent weight is 1.80 times its true weigh

Vikki [24]

Answer:

The velocity at the top will be 26.4522 m/sec

Explanation:

We have given

The diameter of the loop d = 48.01 m

Radius of the loop $r=\frac{d}{2}=\frac{51}{2}=25.5m$

The apparent weight at the top is given by $\frac{mv^2}{r}-mg$

As the in question it is given that apparent weight is equal to 1.80 times of the real weight

$\frac{mv^2}{r}-mg=1.8mg$

$\frac{mv^2}{r}=2.8mg$

$v=\sqrt{2.8rg}=\sqrt{2.8\times 25.5\times 9.8}=26.4522m/sec$

So the velocity at the top will be 26.4522 m/sec
