Answer:
6m
Explanation:
The initial potential energy of the block P.E =mgh
where mass m = 3kg
g= 9.81 m/s2
h = 2m
Hence P.E = 3*9.81*2 = 58.8 Joules
This energy converts to kinetic energy when the block is released from the top
K.E = 
Solving for v, we obtain 6.26 m/s
The acceleration of the block by Newton's second law of motion,
ma = (μk)*mg
where μk = 0.1
Hence, a = 0.1*9.81 = 0.98m/s/s
Applying Newton's second equation of motion to solve,
where u = 0 m/s (released from rest0
Hence, 
Solving for s,
s= 20m
Therefore, the distance after two complete cycles = 20 -2(7) = 6m

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.

The best answer would be C. Amplitude is the measure of the distance between the crest and the center of the line, or the distance between the trough and the center of the line (like wave height). High waves are a sea danger, especially to small ships and rowboats.
