Make an experiment and answer the question below: 1. Place the can on its side on a flat smooth surface like a table or a smooth floor. 2. Rub the blown-up balloon back and forth through your hair really fast. 3. Now the fun part – Hold the balloon close to the can without actually touching the can. The can will start to roll towards the balloon without you even touching it! Try This Too: While you’ve got the balloon out, tear up part of tissue into tiny pieces about 1/4 inch (.5 cm) big. Rub the balloon on your hair again and bring it close to the tissue pieces. They will be attracted to the balloon and then jump away. When you rub the balloon through your hair, invisible electrons (with a negative charge) build up on the surface of the balloon. This is called static electricity, which means “non-moving electricity” The electrons have the power to pull very light objects (with a positive charge) toward them – like the soda can. to answer these questions: 1. Does the size of the balloon change the power of the pull? 2. Does the length of the person's hair affect the power of static electricity? 3. How much water can you put in the can until the balloon can’t pull it anymore?

Expert Solution

1- Yes, it does.

The entirety this is in a liquid or a gas, which includes air, has an upward pressure on it that is identical to the load of the liquid or gas that it displaces. Whilst extra helium is brought to a helium balloon or more warmness is brought to the air in a hot air balloon, the balloon expands, so it displaces a greater quantity of air, which will increase the upward force.

2- Yes, it does.

hair is produced using keratin which is a similar sort of protein that is additionally found on nails and skin. The static charges in our hair are conveyed by keratin. The proteins that decide the colour of hair don't influence the capacity of the keratin to convey static. In this manner, the colour of hair doesn't impact the measure of friction based electricity created by the hair. But the physical properties of the hair, for example, its thickness, can influence the measure of static charge delivered on.

3- if we keep a little water ,it can move because it is lighter ,if it is heaviour it can't move. So half or less filled can.
