Answer:
The correct answer is A
Explanation:
That water stops moving once it gets to the dam and turns into potential energy
It is -2 because the charge will be at zero and electrons lower the charge
we are asked in this problem to determine the mass of a liquid in a small container. In order to determine the mass, we use an analytical balance for greater accuracy by first weighing the whole system (liquid+beaker). Then transfer the liquid to another container and completely dry the beaker (wash and dry). measure the weight of the beaker. The mass of the liquid is equal to the mass of the system minus the mass of the beaker.
Gaining of electrons is reduction and loss of electrons is oxidation.
