Water Potential is the measure of the ability of water molecules to move freely in solution. A solution of pure water where there is no solute and all of the water molecules are free to move, the water po...

We use Newtons equation for gravitational force. F=GMm/r² .1 AU is the mean distance at which the Earth orbits the Sun, taken to be: 1.49x10¹¹ m.Substituting in the numbers we find t...

In a collision where no external forces act linear momentum is conserved.Convention: Right + left -0=-13x28 + 21xVV=17.33 kg m/s to the right
