p = mv
Answer:
Soap breaks up the oil into smaller drops, which can mix with the water. It works because soap is made up of molecules with two very different ends (one end of molecules are hydrophilic, so they love water; the other end of molecules is hydrophobic, so they hate water).
Answer:a supposition or proposed explanation made on the basis of limited evidence as a starting point for further investigation.

Answer:
4 m
Explanation:
From the question given above, the following data were obtained:
Initial velocity (u) = 10 m/s
Acceleration (a) = –8m/s²
Time (t) = 2 s
Displacement (s) =?
The displacement of the object can be obtained as follow:
s = ut + ½at²
s = (10 × 2) + (½ × –8 × 2²)
s = 20 + (–4 × 4)
s = 20 + (–16)
s = 20 – 16
s = 4 m
Thus, the displacement of the object is 4 m.
