Answer:
a = 5 [m/s²].
Explanation:
To solve this equation we must use the following equation of kinematics.
where:
Vf = final velocity = 25 [m/s]
Vo = initial velocity = 5 [m/s]
a = acceleration [m/s²]
t = time = 4 [s]
Note: The positive sign for the acceleration in the above equation means that the car is increasing its velocity.
25 = 5 +a*(4)
25 - 5 = 4*a
20 = 4*a
a = 5 [m/s²]
Answer:
Pangaea
Explanation:
The Earth's crust is not one solid block but is made of different segments called tectonic plates. At one point it started to break apart. The land mass was present around the Paleozoic and Mesozoic eras. This land mass was called Pangaea
As a result all the water on Earth was a part of an ocean called Panthalassa. The concept of the one land mass and one water mass was proposed be Alfred Wagner.
Hence, the statement here is referring to Pangaea.
Answer:
Structural
Explanation:
Structural adaptations are a change to a organism's body, gills are part of the fish's body which would be why this is a structural adaptation!
Hope this helped! Stay safe have a good day or night!
