Explanation:
Continental rifts and mid-ocean ridges are both features of a divergent plate margin.
In both cases plates are moving away from one another. Therefore they are creating new land masses.
- A continental drift like the east African rift valley is where a continent begins to pull apart or diverges.
- A mid-ocean ridge is divergent margin in the ocean.
They are different in that, continental rift occurs within the continental plate that are on land.
But:
Mid-ocean ridges are in the oceanic crust in the ocean . They form the largest physiographic structure on the earth surface called the mid-ocean ridge.

Answer:

Explanation:
The acceleration of an object is the rate of change of velocity of the object.
Mathematically, it is calculated as:

where
u is the initial velocity
v is the final velocity
t is the time taken for the velocity to change from u to v
Acceleration is a vector, so it is important to also take into account the direction of the velocity.
For the particle in this problem, we have:
u = +48 m/s is the initial velocity (positive direction)
v = -92 m/s is the final velocity (negative direction)
t = 4.5 s is the time interval
Therefore, the average acceleration is
