Permeability is a measure of how fast a liquid can pass
through a layer of solid. In this case, the lesser the time, the more permeable
the solid is. Or the other way around, the bigger the time, the less permeable
the solid is. Therefore the answer in this problem is:

Answer:
(a) 1.21 m/s² (b) 1.75 m/s²
Explanation:
The initial speed of the car, u = 17.8 m/s
Case 1.
Final speed of the car, v = 23.5 m/s
Time, t = 4.68-s
Acceleration = rate of change of velocity

Case 2.
Final speed of the car, v = 15.3 m/s

Hence, this is the required solution.
When objects fall to the ground, gravity causes them to accelerate. Acceleration is a change in velocity, and velocity, in turn, is a measure of the speed and direction of motion. Gravity causes an object to fall toward the ground at a faster and faster velocity the longer the object falls
Answer:
Active—A volcano is active if it is erupting, or may erupt soon. ...
Dormant—A dormant volcano is one that may have erupted before, but it is no longer erupting. ...
Extinct—An extinct volcano is not erupting and will never erupt again.
