How do invasive species spread? identify three methods.Why do invasive species pose such a threat?
seropon [69]

Answer:

See the explanation below.

Explanation:

A species is invasive can be spread, naturally either by the behavior of the species, or introduced accidentally or voluntarily by man.

The invasive species increases its density in the occupied area or colonizes new territories over time.

That an invasive species is harmful means that it produces significant changes in the composition, structure or processes of natural or semi-natural ecosystems, endangering native biological diversity.

Uncontrolled reproduction of this invasive species also increases the risk of control and extermination of the species, due to the acclimatization of the new species in the environment as well as possible exponential reproduction.

A marble is thrown horizontally with a speed of 15.0 m/s from the top of a building. When it strikes the ground, the marble has
jolli1 [7]
The answer is 52.79 m.

I used this formula to get the formula for Vy:
v^2=vi^2+2(a)(x)
And got
Vy=square root (19.6 h)

Then I used that and put it in this formula:

tan(65) =Vy/Vx

tan(65) = square root (19.6 h)/15.0

Then I rearranged it to:

h=[(15.0)(tan65)]/19.6

h=52.79 m

A stone was dropped off a cliff and hit the ground with a speed of 96 ft/s. What is the height of the cliff? (Use 32 ft/s2 for t
nadezda [96]
The initial velocity of the stone is 0 ft/s. Given the initial velocity (Vi), final velocity (Vf), and acceleration due to gravity (g), the distance may be calculated through the equation,
                                     d = ((Vf)² - (Vi)²) / 2g
Substituting the known values,
                                     d = ((96 ft/s)² - 0))/ (2x32.2)
The value of d is 143.10 ft.
