how long does it take a skateboarder going 6.0 m/s to come to a complete stop if she slows down at a rate of 2.0 m/s^2

emmasim [6.3K]

Use the formula: v=v0+at

v is the final velocity

v0 is the initial velocity

a is the acceleration

t is the time

Plug in and solve for t:

0=6+(-2)t

*Subtract 6 from both sides*

-6=-2t

*Divide both sides by -2*

3 seconds=t

Hope this helps!!

A bird is observed to nest along the coastline. It then spends hours out in the open ocean feeding on fish. What is this behavio

3241004551 [841]

Answer:

Nesting & Foraging behavior

Explanation:

Seabirds are generally tertiary consumers and / or marine predators that, in marine foodwebs, occupy the upper trophic level. They are very well adapted to all marine ecosystems and feed on a variety of prey: from micro-crustaceans to fish and cephalopods.

Generally, seabirds are observed performing a nesting behavior, by laying eggs near the shore, and then are found exhibiting foraging behavior -searching and foraging for prey- in both the coastline and pelagic zone, also known as the open sea.

Seabirds exhibit different foraging behaviors, for example, the surface feeding behavior which involves flying along the surface with their beak in the water. Gulls, albatrosses and petrels are examples of surface feeders.

On the other hand, plunge diving involves preying on fast marine organisms by diving into the water during their flight. Pelicans are example of seabirds who engage in this behavior.
