A battery operated DVD player uses 12 DV volts from AA batteries and draws a current of 3 A. Calculate the resistance.

Below are three graphs. The shape of graph 3 shows that the current flowing through this component is __________ proportional to

dalvyx [7]

The relationship between variables might be either directly porportional to each other or inversely proportional to each other. <em>For instance, the current flowing is _</em><em><u>directly</u></em><em>_ </em><em>proportional to the potential difference across</em> it.

---------------------

Since I do not have the graph, I will propose two potential options and I will describe each of them.

I suggest you to choose the one that matches the shape of graph 3.

<h3>Graphs</h3>

Probably your graph is composed of the X and Y axes, perpendicularly placed, in a way in which four quadrants are formed.

You might see that one of the axes represents the current (I), and the other one represents the potential difference (V).

And a straight line that represents the relationship between the current and the potential difference.

The direction of the straight line reflects the relationship between variables.

The change on each variable is proportional to the change on the other variable. Now we have to analyze how that change occurs.

<h3 /><h3>Option 1 </h3>

<em>The current flowing through this component is __</em><u><em>DIRECTLY</em></u><em>__ proportional to the potential difference across it</em>.

If this is the case of your graph, you should see the straight line crossing from the left inferior quadrant to the right superior one.

The direction of the line suggests that one of the variables increases as the other one increases too. <em>The current increases as the potential increases. </em>

<h3 /><h3 /><h3>Option 2 </h3>

<em>The current flowing through this component is __</em><u><em>INVERSELY</em></u><u><em>_</em></u><em>_ proportional to the potential difference across it.</em>

If this is the case of your graph, you should see the straight line crossing the right quadrant from the superior left corner to the inferior right one.

The direction of the line suggests that the variable represented in the Y ax decreases as the other one increases.

For instance, The current decreases as the potential increases. Or the potential decreases as the current increases.

In the attached files you will find graphs of both options.

George walks to a friend's house. He walks 750 meters North, then realizes he walked

Sauron [17]

Answer:

I think you are looking for the velocity, so the answer is 38.5 m/s

Explanation:

Velocity is giving by displacement/time. North will be positive and South will be negative, George travels 750 meters then travels -250 meters his displacement is then 750 - 250 or 500 meters. Divide that by 13 seconds to get 38.5 m/s.

The process of _____ is involved in the operation of all heat engines.

faltersainse [42]

The process of heat exchange is involved in the operation of all heat engines.

<u>Explanation:</u>

A heat engine refers as the system which converts thermal or heat and chemical energy into mechanical energy. Then, these can be utilised for mechanical work. This is done by raising the active substances from higher to lower temperature state. In simple words, it produces macroscopic movement from the heat.

For example, when people rub their hands, friction converts mechanical energy (the movement of our hands) into thermal energy (hands warm up). Heat engines work exactly the opposite; they take energy to warm up (in relation to the environment) and release it for movement. This movement is often transformed into electricity by a generator. It shows that there is exchange of heat involved in all of its processes.
