Explanation:
According to newtons first law of motion:
'' a body will continue in its state of rest or uniform motion along a path unless it is acted upon by an external force".
A body in equilibrium that is floating will be stable and not move in any direction. Even if it moves, the motion will be constant wouldn't change.
- To move the body in any direction, one has to swim.
- Swimming is the application of an external force to counter the balanced forces at equilibrium on a body.
- This works when the net external force is greater than that the balanced forces.

Its 1.0*10^-7M its considered a concentration because hydrogen ion is exactly equal to hydroxide ions produced by dissociation of water
V=r/t
Speed equals displacement over the time
V=100/9.92=10.08ms^-1
You would do distance divided by speed. So 150÷3, which would equal 5km per hour.
