Answer:
The minimum difference between the lengths of the two tubes should be 0.385 meters.
Explanation:
As we known that for any two waves to arrive in phase at any point the difference in the path traveled by the waves should be an integral multiple of the wavelength of the wave.
Mathematically we can write:
For the given wave we have
Applying values we get
Thus the minimum difference in the lengths of the tubes can be obtained by putting the value of n = 1
Answer:modeled as an electromagnetic wave. In this model, a changing electric field creates a changing magnetic field.

Answer:
- Because the mass is also 6 times greater, so the acceleration is the same.
Explanation:
Force is mass multiplied by acceleration. This is (in one dimension):
Now, we can see what acceleration will every rock feel:
Lets call the force over the first rock, that has a mass , and lets call the force over the second rock, that has a mass . We can write the following equations:
and
.
We also know that:
, so:
.
But the mass is also six times greater.
so...
.
Now, lets obtain the acceleration. For the first rock we got:
and for the second rock
But this is the same acceleration that the first rock has! So, the kinematics will be the same.
