Answer:

introduction of new animals and crops to North America

Explanation:

Since the early 1500s, Europeans have transported old world species to their new settlements in the Western Hemisphere, as well as to other parts of the world. The manifestoes of Christopher Columbus' second and subsequent voyages, for example, mention the deliberate transportation of species considered potential crops and livestock. Global trade has grown astronomically since then, providing an opportunity for the corresponding growth of biological invasions. Consequently, biological invasions can be viewed as a predominantly post-Columbian event. Put in perspective, the movement of organisms caused by humans, accidentally or deliberately in the last 200 to 500 years, undoubtedly dwarfs in frequency and impact the movement of organisms by natural forces at any 500-year period in Earth's history.

A rocket is fired at 100 m/s at an angle of 37, how many seconds did it take to get to the top?
Kobotan [32]

Answer:

6.14 s

Explanation:

The time the rocket takes to reach the top is only determined from its vertical motion.

The initial vertical velocity of the rocket is:

u_y = u sin \theta = (100)(sin 37^{\circ})=60.2 m/s

where

u = 100 m/s is the initial speed

\theta=37^{\circ} is the angle of launch

Now we can apply the suvat equation for an object in free-fall:

v_y = u_y +gt

where

v_y is the vertical velocity at time t

g=-9.8 m/s^2 is the acceleration of gravity

The rocket reaches the top when

v_y =0

So by substituting into the equation, we find the time t at which this happens:

t=-\frac{u_y}{g}=-\frac{60.2}{-9.8}=6.14 s

5g of ammonium nitrate was dissolved in 60g of water in an insulated container. The temperature at the start of the reaction was
Minchanka [31]

Answer: The energy absorbed by the reaction from the water is 996 Joules.

Explanation:

Energy absorbed by the reaction or energy lost by the water to the reaction,Q.

Mass of the the reaction  ,m = 60 g

Specific heat of water = c = 4.15 J\g ^oC

Change is temperature=\Delta T=19^oC-23^oC=-4^oC

Q=mc\Delta T=60 g\times 4.15 J\g ^oC\times (-4^oC)=-996 Joules

Negative sigh indicates that energy was given by the water to the reaction.

The energy absorbed by the reaction from the water is 996 Joules.
