Answer:
4.2 m/s
Explanation:
Momentum is conserved.
m₁u₁ + m₂u₂ = m₁v₁ + m₂v₂
(35 g) (9 m/s) + (75 g) (-7 m/s) = (35 g) (-15 m/s) + (75 g) v
315 g m/s − 525 g m/s = -525 g m/s + (75 g) v
315 g m/s = (75 g) v
v = 4.2 m/s
Answer:
There are several reasons for the extinction of species. Some of these can include climate change, natural disasters, environmental destruction, or over-hunting. All of these factors can contribute to the deaths of various animals which ultimately leads to extinction if left unchecked.
Explanation:
Answer:
Subduction occurs and a trench is formed.
Explanation:
- When a tectonic plate carrying an oceanic crust collides with a tectonic plate carrying a continental crust then the oceanic plate will slide beneath the continental one, forming a trench.
- This is possible because the oceanic crust is less dense than the continental crust.
Subduction is a geological phenomenon in which the tectonic plates of one crustal plate descends below the edge of the other. The region where this happens is called a subduction zone.
