Answer:

The answer is: It remains constant throughout the entire swing.

Explanation:

The "total mechanical energy" refers to the sum of the potential energy and the kinetic energy. When it comes to swinging pendulum, the total mechanical energy refers to the sum of the "gravitational potential energy" and the "kinetic energy."

Remember that the pendulum is "not in free fall" because it is constrained by a string. The tension in the string is being balance by a gravitational force that is acting on it. So, when the pendulum swings (back and forth), the gravitational potential energy and the kinetic energy undergoes a constant exchange of energy. So,<u> this allows the mechanical energy to be conserved.</u>

If friction is present<u>,</u><u> the mechanical energy will then be turned into other forms of energy.</u>

s344n2d4d5 [400]

Answer:

Being a weak acid and a strong base, where it is diluted in a neutral medium such as water, the basic medium predominates, almost alkaline pH.

Explanation:

The acidity of the solution, being weak, means that its pH is not so low, therefore it will be easier to reach the values of 7 or 7 where alkalinity or basity is indicated.
