How many pieces of paper can a helium balloon pick up?
it depends on the size of the balloon and the size of the paper
Is paper attracted to magnets?
No.
What is the force is acted when the paper clips are attracted to magnet?
gravity
Do you expect paper clips to be attracted or not a attracted to a magnet?
Paperclips can be held by a magnet but are not usually sold magnetized themselves.
How do you make a model motor neuron cell?
I would do one in paper mache'. Take a balloon and then tear strips of paper, get craft glue or wheat paste and put your paper in it . Make sure your strips of paper are well coated with the glue/paste. Now put the strips of paper over your balloon because you are going to make a head. You want this fairly thick on the balloon. Don't want to see any blank spots on the balloon. Let it dry. When it is fully dry pop the balloon and now you will have a paper mache head. Get tempera paint and paint it one color. Then draw your brain on it and label using different colors for each section. Now, you can go through the bottom of your head and put in LED lights in the areas you want to light. This should work. I stess that the paper strips must be thick on your balloon.
When a glass rod charged its placed near small pieces of paper bitsthe paperbits are attracted to the rodthen repelledexplain?
The glass rod aquires static electricity.the paper bits are negatively charged and the glass rod is positively charged.when it battracts the paper ,the both aquire like charges due to which they both are repelled.
What is negative about paper?
The paper is probably negatively charged, polar too, hence absorbs water.
Paper hop project?
Paper Hop Problem: How can we show that atoms have positive and negative charges? Hypothesis: If we can rub some electrons off an item, and make it positively charged, then it will stick to an item of the opposite charge. Materials: piece of notebook paper, paper hole puncher, small balloon, clean hair Procedure: 1. Use the hole punch to cut about 15-20 small circles from the piece of paper. 2. Spread the pieces on a table. 3. Inflate the balloon and tie it. 4. Rub the balloon against your hair about five strokes. 6. Hold the balloon close to, but not touching, the paper circles. Observations: The paper circles jump to the balloon. Conclusion: Paper is an example of matter, and all matter is made up of atoms. Each atom has a positive center with negatively charged electrons spinning around outside. The balloon rubs the electrons off of the hair, giving the balloon an excess of negative charges. The positive part of the paper circles is attracted to the excessive negative charge on the balloon. This attraction between the positive and negative charge is great enough to overcome the force of gravity and the circles will hop upward toward the balloon.
Why a peace of paper attracted towards a charged object?
Most of the time, in an object, its negative and positive charges are balanced, which makes it a neutrally-charged object. Sometimes, when some objects come into contact with other things, they gather more charges of one type. If there are more electrons, they are negatively-charged. If there are more protons, they are positively-charged. Because opposites attract, an object which is negatively-charged will attract another object which is positively-charged and vice versa.
Why don't the attractive and repulsive forces cancel outwhen a negatively charged rod is brought close to some small pieces of neutral paper. The positive sides of molecules in the paper are attracted?
The The molecules in the paper will orient themselves so that the positively charged sides point towards the rod and the negatively charged sides point away. Since the electrical forces decreases with increasing distance the nearer positive charges experience a stronger force than the more distant negative charges. As a result, the net force will be one of attraction.
What happens when you rub an acetate strip with tissue paper and then hold the strip near running water?
If you rub an acetate rod with a cloth electrons are transferred from the rod to the cloth and the rod becomes negatively charged and the cloth becomes positively charged.
Why a ruller will attract pieces of papers?
when you rub the plastic ruler on e.g. a yellow duster it takes the electrons (which is the negative charge) from the yellow duster and the plastic ruler becomes negatively charged. The paper has both protons and electrons the protons are positively charged. and very much like a magnet the negative is attracted to the positive hence the paper sticks to the ruler Hastings Tarrant
What type of printer uses a beam of light to generate characters on paper?
A laser printer uses a beam of light to generate text and images on to paper. The laser is used to create a negatively charged image on parts of the printer drum. The toner then sticks to the areas of the drum that is negatively charged before being transferred to paper.
Examples of electrostatic force?
paper sticking to a charged CD water attracted to an ebonite rod
What happens if you hold the balloon over the paper for several minutes?
If you hold the balloon over the paper for several minutes, nothing significant will happen. The balloon will continue to hold its shape, and the paper will not be affected by it. The only change you may observe is a slight static charge buildup on the balloon, which could potentially cause lightweight objects like the paper to be attracted to it.
Why a comb drawn through hair attracts a tiny piece of paper?
This is due to electrification process. As we rub the comb along with hair, the molecues in the comb would lose some electrons to the hair. This happens due to friction. So comb due to lack of negatively charged electrons becomes positively charged. Same time hair gaining electrons becomes negatively charged. Now as we keep this charged comb close to a bit of paper, then by electrostatic induction opposite charges here negative electrons are pulled towards it. So paper gets negative charge momentarily. Hence force of attraction between unlike charges. So paper bit gets attracted.
What printer use a drum and toner in the printing process?
A Laser printer uses a drum and toner. A laser negatively charges the drum (a big rotating tube) at certain points, making a mirror copy of the item to be printed. The drum rotates past a toner cartridge, in which are positively charged particles of toner. The positively charged toner is attracted to the negatively charged parts of the drum, and leaves the neutral space in between blank. The drum then presses onto a sheet of paper, transferring the image. A quick heat of the paper seals in the toner (That's why the paper is always warm when it comes out of the printer), and there you go, an image!
