Arrow A represents the direction of the electric field vector at the position of the dot.
A dot indicates the location of an electric charge at a certain location. The electric field line will radiate outward in the case of a positive charge. If the charge is negative, the electric field will radiate outward from it. The direction of the electric field at a certain location is not, however, shown by the dot. As a result, reading the values of negative signs on a field line is useless.
As compared to the negative charge, the positive charge, Q, is twice as distant from the dot. We must first measure the intensity of the electric fields in order to determine the electrical field at a certain location. The positive charge is represented by +Q in Figure Q20.5, whereas the negative charge is represented by -1. The intensity of the electric field at a spot represented by a dot must thus be equal to the total of the electric fields pointing in that direction.

I want to say A.) to protect consumers from purchasing poor quality products. but I'm also debating on letter B.
I hope this helps
Non-rapid-eye-movement sleep (NREMS), rapid-eye-movement sleep (REMS), and W are regulated by several Neurotransmitter systems and a number of diffusible or circulating factors.
Neurotransmitters are chemical messengers that your body can't function without. Their job is to carry chemical signals (“messages”) from one neuron (nerve cell) to the next target cell. The next target cell can be another nerve cell, a muscle cell or a gland.
The DA-containing cells of the VTA and SNc mission to the basal ganglia and the prefrontal cortex, even as these correspond to the PAG mission predominantly to the BFB and midline thalamus. moreover, OX-containing neurons bring projections to the entire forebrain and brainstem arousal structures. three as pointed out by using España and Scammell, four isolated activations of every of the arousal systems already provoke W. but, below regular situations, all of them participate in the occurrence of behavioral and electroencephalographic (EEG) arousal. This depends, in element, on the interconnections of maximum W-promoting structures. similarly, the systems that promote W inhibit neural structures located inside the brainstem and hypothalamus that promote and/or induce NREMS and REMS.

Mostly English political philosophy, like John Locke.

Federal legislation that requires states and municipalities to comply with certain rules is known as a federal mandate.
