Hydraulic conductivity (K) is a property of soil<span> that describes the ease with which water can move through </span>pore<span> spaces. It depends on the permeability of the material (</span>pores, compaction) and on the degree of saturation. Saturated hydraulic conductivity, Ksat<span>, describes water movement through saturated media.</span><span />
Answer: Negative
Explanation:
An oxygen atom has the chemical symbol O. Its atomic number is 8, with an electronic configuration of 1s2, 2s2 2p4.
Now, due to the incompletely filled p-orbital, oxygen picks up two additional, free-floating electrons (2e-) to complete its outermost shell. And since each electrons received carries a negative charge, oxygen atom becomes a negatively charged divalent ion, O2-
See the equation below
O + 2e- ---> O2-
Answer:
The time it takes light to cover 1.5 km was too short to be measured by Galileo's instruments.
Explanation:
The speed of light is 
, which means the time it takes to cover a distance of 1.5 km (or 1,500m) will be
which is 
of a second! This time delay could in no way be measured by Galileo considering the fact that he was using his heartbeat to measure time!
