The weight of 20 band-aids can vary depending on the brand, size, and material. On average, a standard band-aid weighs about 0.3 grams, so 20 band-aids would weigh approximately 6 grams.
Well it depends on how much rubber you have
If the stretching of a rubber band is too much, it can lead to the band losing its elasticity and eventually breaking. This is because the molecular structure of the rubber band becomes permanently deformed, affecting its ability to return to its original shape.
The force exerted by a rubber band is called tension. This force occurs when the rubber band is stretched or pulled, causing it to resist and try to return to its original shape. The amount of force exerted depends on how much the rubber band is stretched.

If weight is added to a rubber band, it will stretch and elongate. The amount of stretch will depend on the elasticity and strength of the rubber band. Eventually, if too much weight is added, the rubber band may break.
The speed of a rubber band when flung can vary depending on factors like how much force is applied and the elasticity of the rubber band. Typically, rubber bands can reach speeds between 15-30 miles per hour.
The cost of one rubber band is typically very low, usually just a few cents. It can vary depending on the brand and type of rubber band, but they are generally an inexpensive item to purchase.
The energy stored in a rubber band when it is pulled back is potential energy, which is converted to kinetic energy when released. The amount of energy produced when releasing a rubber band depends on factors like how far it is pulled back, the elasticity of the band, and any resistance forces.
they float because they do not weigh to much and are hollow
The cost of 1 rubber band can vary depending on the brand and quality. On average, a basic rubber band typically costs less than a cent when purchased in bulk. However, prices may vary if you're looking for specialty rubber bands.
No. You also need to know the properties of the rubber band - specifically, how much it stretches for every unit of force applied.
