Answer:
B: beaks, finches.
Explanation:
Beaks, finches. This is because he noticed that fruit-eating finches had beaks similar to parrots, while finches that ate insects had narrow beaks. The difference in their beaks is due to adapting to different environments which causes them to evolve into different species of finches.
Answer:
(a) 38.5m/s
(b) 64.4m/s
Explanation:
First, we can obtain the launch speed from the definition of kinetic energy:
Plugging in the given values, we obtain:
Now, from the conservation of mechanical energy, considering the instant of launch and the instant of maximum height, we get:
And with the known values, we compute:
Finally, to know the components of the launch velocity, we use trigonometry:
It means that the horizontal component of the launch velocity is 38.5m/s (a) and the vertical component is 64.4m/s (b).
Answer:
This is a chemical property. If iron does rust, this is a slow chemical change since rust is an iron oxide with different properties than iron metal.
