I took that
one of several competing scientific models that all seem equally successful in explaining the nature of life on Earth
Explanation:
- The theory of evolution is one of the several competing scientific models that all seems to successfully explain the nature of life on earth.
- A theory is usually drawn from careful observation of scientific investigation.
- Theories generally provides explanation into a phenomenon that occurs in nature.
- They are products of careful scientific observations and experiments.
- The theory of evolution is but one of them.

Answer:
The statements that best compares radiation and conduction are the following: both transfer thermal energy from warm objects to cooler objects and both can transfer energy through matter. The difference is that conduction is through direct heat transfer; whereas, radiation transfers heat through waves.
Answer:
The amplitude of the wing tip's motion is 1.6 mm.
Explanation:
Given that,
Beat = 250 /s
Speed = 2.5 m/s
We need to calculate the amplitude of the wing tip's motion
Using the equation for the maximum velocity
Where,
v = speed
f = frequency
A = amplitude
Put the value into the formula
Hence, The amplitude of the wing tip's motion is 1.6 mm.
