Answer:
The answer is B. composition
Explanation:
- The speed of a seismic wave is governed by three interrelated factors, viz. the composition of the rock, pressure, and temperature.
- Seismic waves travel at different speeds in different mediums.
- This property of the seismic waves tends it to change the speed where the concentration of minerals in the rocks varies.
- Other than that, the increasing temperature beneath the Earth's surface decreases the speed of the seismic waves, and the speed increases with increasing pressure as the waves go penetrating deep down into the Earth's interiors.

Answer:
<em>J=600 kg m/s
</em>
Explanation:
<u>Impulse And Momentum
</u>
Suppose a particle is moving at a certain speed 
and changes it to 
. The impulse J is equivalent to the change of linear momentum. The momentum can be computed by
The initial and final momentums are given, respectively, by:
Thus, the change of momentum is
It's equal to the Impulse J
Our data is
