The answer is commensalism because commensalism is a relationship where an organism is benefitted and the other is neither benefitted nor harmed. The barnacle is being benefited and the whale is not being benefited or harmed.
Work done = force x distance
work done = 15 x 3
work done = 45J
Answer:
![v=697.2km/h](https://tex.z-dn.net/?f=v%3D697.2km%2Fh)
Explanation:
Hello.
In this case, since the velocity is computed via the division of the distance traveled by the elapsed time:
![V=\frac{d}{t}](https://tex.z-dn.net/?f=V%3D%5Cfrac%7Bd%7D%7Bt%7D)
The distance is clearly 1743 km and the time is:
![t=2h+30min*\frac{1h}{60min} =2.5h](https://tex.z-dn.net/?f=t%3D2h%2B30min%2A%5Cfrac%7B1h%7D%7B60min%7D%20%3D2.5h)
Thus, the velocity turns out:
![v=\frac{1743km}{2.5h}\\ \\v=697.2km/h](https://tex.z-dn.net/?f=v%3D%5Cfrac%7B1743km%7D%7B2.5h%7D%5C%5C%20%5C%5Cv%3D697.2km%2Fh)
Which is a typical velocity for a plane to allow it be stable when flying.
Best regards.
Answer:
X
Explanation:
v=u+at but t is constant so
a=v-u
for x
a=29-10
a=19
which marks the greater acceleration
The speed of a chemical reaction is affected by four factors: enzymes, concentration, temperature, particle size, and the presence of a suitable catalyst.
