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:
F1 = k Q1 * Q2 / R^2
If Q1 is doubled then F2 = 2 F1 = 72 units
Well, they are equal and opposite, but the force is high enough to break up the snowball. That is where the energy is dissipated.
Answer:
law stating that the ratio of the sines of the angles of incidence and refraction of a wave are constant when it passes between two given media.
Snell's law, in optics, a relationship between the path taken by a ray of light in crossing the boundary or surface of separation between two contacting substances and the refractive index of each. ... Snell's law asserts that n1/n2 = sin α2/sin α1.
