D) where water covers the land
Answer:
or 308 J
Explanation:
Work in physics is done when an object is moved due to an applied force. But you need to remember that work is only done if there is movement parallel to the direction of the force applied.
Work can be computed with the formula:
W=Fd
Where:
F = Force
d= distance
So your problem gives you:
F = 22 N (Newtos)
d = 14 m (meters)
All you need to do is plug in the values and multiply:
W = F x d
W = 22N x 14m
W = 308 N-m or 308 J (Joules)
The correct answer is A. When free hydrogen ions and free hydroxyl ions are removed from solutions of acids and bases, the acidic and basic properties disappear.
The strength of the acid or base depends upon its degree of ionization. Since different acids and different bases dissociate or ionize to different extent in water so their degree of ionization is also different. Strong acids and strong bases ionize in water completely while the weaker acids or bases ionize partially. Ionization of the weak acids in water are in equilibrium. The degree of ionization is the ratio of the number of ionized molecules to the number of molecules which are dissolved in water. In case of acids the ionized molecules are hydrogen ions and in case of bases hydroxyl ions.
