When a device uses two batteries why do they have to be placed positive to negative?

Batteries placed in series (which is what you're describing) add their voltages together.
Thus two 1.5 volt batteries give 3 volts in series ... IF they point in the same direction.
If they point in opposite directions, you get zero volts.

A negatively charged object is placed within a positive electric field. what happens to the object?
Electric Field between positive and negative charges. If the Electric Field in which both the positive and negative charges are present is stronger than the Electric Field between the two charges we are talking about, the the negative charge will move away from the positive charge in that positive direction of the field. If not, then the negative charge will get attracted to the positive charge and stay at the position of the positive charge. It will be pulled toward the source of the electric field. (Novanet)
Is salt an ion?
No, not in its solid (dry) state. Table salt - solid sodium chloride (NaCl) - is comprised of one atom of sodium and one atom of chlorine. When it is dissolved in water, that is to say (ie) placed in an aqueous solution, it disassociates into two ions, a positive one (Na+1) and the oppositely charged negative one (Cl-1) ; which together, outside of solution, form an electrically neutral molecule.
Should a patient with a gram positive cocci sputum specimen be placed in respiratory isolation?
yes
Explain how the dielectric material or medium of electrical charges affect the value of potential energy?
the dielectric placed between the positive and negative plates of a capacitor prevents the collapse of plates due to so strong attractive forces between them and retains the potential difference between the plates.....
How do you explain why a magnet will not attract to a plastic paper clip?
When you place magnets on a pencil they will usually not touch each other, this is because of their magnetism. It means you've placed the magnets on sides similar to each other; a magnet has two sides, a positive and a negative. If you place a positive with a negative, they stick together, but when you place a positive with a positive, or a negative with a negative, then they will push against each other. And since the magnets on the pencil have little room to move, when they push against each other they don't touch, and they seem to float.
How do you wire three 12 volt batteries to get 36 volts?
The batteries need to be wired in a series configuration. Wire the negative of the first battery to the positive of the second battery, and the negative of the second to the positive to the third. If the batteries were placed in a straight line they will look like train cars, with all positive ends of the batteries pointing in the same direction. The batteries voltages are now added together for three 12 volt batteries making 36 volts.
How are positive and negative numbers placed on a number line?
Positive numbers go to the right of zero, negative numbers go to the left of zero.
What do you call the positive or negative designation placed in front of a number?
Sign
How to Position a Duracell Battery?
Positioning your Duracell battery is essential to the proper functioning of whatever machine you are placing it in. Try to ensure that you are following the placement directions correctly. These are normally printed on the metal or plastic just above the battery slot. There should be negative and positive indicators on both the battery and the electronic device to help show you where the batteries should be placed.
Which end of battery is placed at the spring side?
With regular dry cell batteries, the flat negative (-) side always sits against the spring.
What happens when opposite poles of a magnet are placed near each other?
Positive and negative attract, or goes together. Positive and positive or Negative and Negative repell, or push away from one anothe
Why are batteries placed in a flashlight the positive terminal of one is connected to the negative terminal of the next?
Because they are connected in series. Lets say you have a flashlight that holds 2 D cell batteries. Each battery puts out 1.5 volts. Connect them in series and together they put out 3 volts. The flashlight is designed to run on 3 volts. A electronic device that uses 4 AA batteries is using 6 volts even though each battery is only putting out 1.5 volts. Connected in series you add to the voltage with the addition of each new battery.
What is an ambrotype?
An ambrotype is an early type of photograph in which a glass negative appears positive when placed on a black background.
Why are the batteries in any electronic device placed oppositely?
A: It may look to you as apposite but I ASSURE YOU PHYSICALLY THEY MAY INSTALLED OPPOSITE BUT ELECTRICALLY THE ARE INSTALLED IN SERIES
