Answer: Broken line

Explanation:

When you collect data in an experiment, you usually need a model where you can analyze the data.

One way of doing this is when in an experiment you expect a given behavior determined by a function (or data obtained by previous investigations), you can graph your obtained data over the graph of the function (or previous data), and in this way, you can see if your data fits in the model.

You usually will graph your obtained data with dots, so usually, we graph the other things with a broken line. This is because if you use a colored line and you do some kind of fitting with your data, the lines may "clash" into each other, making the graph hard to read.

A colored line, as long as it is one single piece, not broken

During action potential, positively charged ________ ions move inside the cell.

Tems11 [23]

During action potential, positively charged sodium ions move inside the cell.

So option D is correct one.

The sodium ion moves inside the cell during a action potential. The stage of action potential is called depolarization . This open voltage gated sodium channel.

Action potentials ( those electrical impulse that send signals around body ) is nothing but more than temporary shift ( from negative to positive ) in the neuron's membrane potential caused by ions suddenly flowing in and out of the neuron.

It consists of phases:

Depolarization
overshoot
repolarization

An active potential propagates along the cell membrane of an axon until it reaches the terminal button.

1 loop in the primary coil and 8 loops in the secondary. If the secondary voltage is 120 V, what must be the primary voltage

Jet001 [13]

Answer:

$V_{p} = 15 V$

Explanation:

<u>Given the following data;</u>

Number of loops in primary coil, Np = 1 loop.

Number of loops in secondary coil, Ns = 8 loops

Voltage in secondary coil, Vs = 120V

To find the voltage in the primary coil, Vp;

Transformer ratio is given by the formula;

$\frac{V_{p}}{V_{s}} = \frac{N_{p}}{N_{s}}$

Making Vp the subject of formula;

$V_{p} = \frac{N_{p}}{N_{s}} * V_{s}$

Substituting into the equation, we have;

$V_{p} = \frac{1}{8} * 120$

$V_{p} = \frac{120}{8}$

$V_{p} = 15 V$

Therefore, the voltage in the primary coil, Vp is 15 Volts.

How would you quickly determine whether a cleaning

Leona [35]

Answer:

The answer is explained below

Explanation:

If you add dilute HCl (Hydrochloric Acid) to the solution, and you see fizzing, then it is the carbonate. I would recommend doing this under a fume hood, as HCl has a wicked smell, and can make a few people sick to their stomach (however, you probably won't be using 12M concentrated HCl)
