Answer: The water in the pool is acidic
Explanation:
The pH level indicates the concentration of hydrogen ions in a solution and is setted in a scale from 0 (which is acid) to 14 (which is alkaline), being 7 the neutral value.
In this context, the normal pH level in a pool's water must be between 7.2 and 7.6
. So, since this pool's water pH is 6.5 we can say the water is acidic.
It is important to note that this may lead to skin and eyes irritation of the bathers, instability of chlorinated products and corrosion in the metal parts of the pool that are in contact with this water.
Answer:
hypothesis, sorry if I'm wrong
Answer:
A.
Explanation:
A fictional force (also called force of inertia, pseudo-force, or force of d'Alembert, 5), is a force that appears when describing a movement with respect to a non-inertial reference system, and that therefore it does not correspond to a genuine force in the context of the description of the movement that Newton's laws are enunciated for inertial reference systems.
The forces of inertia are, therefore, corrective terms to the real forces, which ensure that the formalism of Newton's laws can be applied unchanged to phenomena described with respect to a non-inertial reference system. The correct answer is A.
