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.

The ____ is a measure of the number of waves that pass a point in a given amount of time
nikitadnepr [17]

The (frequency of the wave multiplied by the number of seconds
in a given amount of time)
is the measure of the number of waves that
pass a point in that amount of time.

If you had said "in one second" instead of "in a given amount of time,
then the word in the blank would simply be frequency.

What is the best explanation of work?
Margarita [4]

Answer:

<u>Work done by the force acting on a body is defined as the product of force and displacement of the body in the direction of the force.</u><u> </u> It is a scalar quantity. Force acting on the body must produce a displacement for the work is to be done by the force. Thus, for the work to be done, the following conditions must be fulfilled:

A force must be applied and the applied force must produce a displacement in any direction except perpendicular to the direction of the force.

Mathematically,

work = force \times  \: displacement

( in the direction of force)

i.e W= F•D

The SI unit of force is Newton (N) and that of displacement of a metre (M). So the unit of work is Newton metre(Nm) which is joule (J).

Thus, one joule work is said to be done when one Newton force displaces a body through one metre in its own direction.

Hope this helps...

Good luck on your assignment..

Two waves can share the same space and pass through one another. What type of interference occurs when the crests of one wave ov
Nastasia [14]
D is the correct answer. Constructive Interference occurs when the crests of one wave overlaps with the crests of another wave. The reason it is called "constructive" is because one wave is adding energy to another wave. Hope this helps!
