Water would have a much lower boiling point much like its other hydrides and it would loss its ability to dissolve polar substances plus it couldn't form water columns so no more cohesion between water molecules
6.8x10^5? Scientific notation
If the forces are equal and in opposite directions, the net force will equal zero.
Consider a tug-of-war team. If they are pulling with equal forces against each other, the red cloth on the rope will not move.
<em>F = ma
</em>
The cloth is not moving, so <em>a = </em>0 and the net force <em>F = </em>0.
I believe it’s c for warm front then f for cold front. I hope that helps!
