Natural gas is the answer.
For this case we have by definition:
v = λf
We observe that we have a linear relationship, where λ is the constant of proportionality.
We have then:
- <em>v: speed of propagation of the wave
</em>
- <em>λ: wavelength
</em>
- <em>f: frequency
</em>
Answer:
The variable that is directly proportional to the frequency is λ, the wavelength.
The answer is (D) Fluorite
Runners complete 20m continuous runs, going from one cone to another. they must get to one cone from another until a beep comes. each time, the time between the beeps decrease.
the multistage fitness test is mostly to measure the power of aerobic.
Answer:
-4.72005 m/s
0 m/s
Explanation:
Displacement = 5220 km
Time = 12.8 days
The average velocity is given by

The average for the return flight is -4.72005 m/s
When the total displacement is divided by the total time of a journey then we get the average velocity.
Displacement is the minimum distance between the initial and final points of the journey.
Here, the displacement of the whole episode is 0 as the initial and final point is zero.
Hence, the average velocity for the whole episode is 0 m/s
