This can vary considerably by the components, type of battery, and by manufacturer. But lithium batteries weigh only about 7.5 grams, alkaline batteries about 11.5 grams, and rechargeable nickel-metal-hydride batteries a whopping 14 to 15 grams each.

How much does a double A battery weigh?
0.81 ounces (23g) AA batteries can be made using several different chemical makeups. While 23g is a good approximation for an alkaline AA it's not a good guess for NiMH or Li Fe2S. The L91 Energizer AA only weighs 14.5g. A good battery manufacturer will have datasheets on their website that will include the weight.
How many watch batteries would equal one AAA?
Most watch batteries produce about 3 volts but cannot supply much current. This is ok because the motor inside a watch only needs a tiny amount of current. An AAA cell produces about 1.5 volts but can supply a lot more current than a watch battery. The amount of current it can give depends on what type of AAA cell it is. (Some cells are Zinc/Carbon, others are Alkaline, Lithium, etc.) Depends on the size of the watch battery. Battery ratings are difficult to determine as the amount of energy stored in a battery depends upon how you fast you discharge it, and of course the manufacturer. In fact most manufacturers do not put any rating on a battery aside from the voltage. But use the volume as a rough guide. Other things being equal, volume should be proportional to energy stored. If you need an exact , you will have to resort to experimentation. Get some of the exact type and brand of battery you want to compare, put loads (resistors) on them and measure output voltage versus time.

How a battery provides energy to a circuit?
In very simple terms, there are two chemicals in a battery - one chemical wants more electrons and the other chemical wants to get rid of electrons. When a path (i.e. circuit) is completed between the two of them (the ends of a typical AA, AAA, D, etc. battery or the two posts on a 9V battery, the electrons are free to move from one post to another. The movement of electrons is current. Different chemicals and/or configurations determine how badly the electrons want to get from one chemical to another. That drive to get from one to another is called voltage potential, and is expressed in volts. How fast the electrons travel between the two chemicals is the flow, or current, and is expressed in Amperes or Amps... for small batteries, it is usually expressed in milliamps because the current is so low. The capacity of the battery is expressed in milliampere-hours which is how many amperes can flow between the chemicals over a given amount of time until the chemicals have exchanged so many electrons that the electrons no longer have any drive to flow between the chemicals anymore.
If a 30kg weight is hanging on a spring and it stretches 0.5m what is the spring constant of the spring?
Hooks law: F=-x*K F=Force x=distance = 0.5m K=constant F=mass*9.81 = 30*9.81=aaaa [N] aaa = -0.5 * K => K = something
