Answer:
20 m/s
Explanation:
The speed of a wave is given by:

where
is the wavelength
f is the frequency
v is the speed
For the wave in this problem,
f = 10 Hz is the frequency
is the wavelength
So the speed is

KHDMDCM.
Now go from Kilometer to Centimeter: 5.
Move the decimal 5 places to the right: 67,500,000 centimeters.
Hope this helps :)
Volcanic islands, Mountain ranges
Explanation:
A convergent margin is plate boundary in which plates comes together. There are different types of interactions that occurs around a place where plate converges.
- An ocean-continent convergence creates a subduction zone in which the denser oceanic plate sinks beneath the less dense continental crust.
- As the oceanic plate begins to subside, it can melt and form chains of volcanic island within the riding continents.
- Also, where two plates of equal densities converge, none of them subsides and this leads to upbuilding.
- The product can be seen as extensive mountain ranges on earth like the Andes and Himalayas.
