that is a paractise question for yr 9 sats
becaud ethe gravity betwen the paper clip is kes
probably because the paper clip weighs less against the magnet
this happens because the magnet has magnetised the nail
if a refrigerator magnet cant hold a piece of paper against a refrigerator, the forces acting on the magnet must be what?
I'd imagine a single sheet of tissue paper is best calculated (assuming uniformity in manufacturing) by counting the amount of sheets and weighing them all together on a balance, then dividing by the amount of sheets to get the average weight
how can I put weight in my paper plane
you can hang as many paper clips as you want until the weight of the paper clips becomes more than the pulling force of the magnet
Magnetic filed of the bar magnet will penetrate a paper. Hence the clip will be attracted and stick to the magnet pressing the paper too to the magnet.
magnet attracts iron. paper clip made of iron magnet atrracts paper clip...
Well, let's see. If I have a paper clip on a table and a magnet in my hand, and I slowly pass the magnet over the paper clip, the magnet in my hand is pulling the paper clip up with magnetism. If my magnet is close enough to the paper clip, the paper clip will jump up to the magnet ... even though the whole Earth is pulling it down with gravity.
Technicly a black hole doesnt have weight it is a rip in the space time continuum. You have to think of it like this if you put iron shavings on a piece of paper they will stay where you put them however if you put a magnet under the paper the shavings will go towards the magnet, this represents gravity but if you cut a hole in the paper where the magnet is the iron shavings will get sucked off of the paper and stuck to the magnet. This is representative of the tiny fraction of th cosmos around any one black hole
Yes. But the attached paper clip will usually not generate a magnetic field as strong as the magnet itself. At some point, either the field will be too weak to pick up another clip, or the weight of the clips will exceed the lifting power of the original magnet. The magnetic field is not affected by water. In fact, the slight reduction in weight due to the buoyancy will normally allow a slightly larger string to be formed underwater than in air.
Just adding weight will not make a paper airplane fly farther. However, adding weight in exactly the right places can make it fly farther, by improving its balance and stability.
A magnetic force.
The paper clip clings to the the magnet
probably because the paper clip weighs less against the magnet
