Seismic waves and water can weaken soil, causing it to move. This is called earthquake and erosion. Earthquake happens when the Earth is shaking and usually causes big damages on infrastructures. Erosion is the slowly breaking of either water, wind, etc.

The answer is liquefaction.

This is a phenomenon that occurs when soil saturated in water or unconsolidated soil becomes a suspension because of an earthquake. The earthquake reduces the strength and stiffness of the soil. The vibrations from the earthquake and water pressure cause the soil particles to loosen.

Which velocity graph shows the car moving toward the right (away from the origin) at a steady (constant) velocity?

slega [8]

Explanation:

$\text{Velocity is defined as the average displacement per unit time.}$

$\text{Since the car is moving at a steady velocity, the velocity does not change over time, it shows a horizontal line on the }v-t\text{ graph}$

$\text{Therefore, only option 2,5,8 matches this requirement.}$

$\text{Since the car is moving to the right, which is defined as the positive direction in this question, the velocity (}v\text{) is also positive.}$

$\text{Therefore, only option 5 is correct.}$

Why electrons flow in a wire when connected to a battery?

vesna_86 [32]

Answer:

The metal atoms in the wire can't move, but their outer electrons can. The force pushes those electrons and they move to further parts of the wire, trying to reach the other end. As the electrons move away, new electrons flow into the wire through the battery to take their place.
