Water waves can move a piece of cork floating on top of the water only in a up and down motion?
True
Is cork a good conductor of heat?
Cork can be used in a lot of ways. Because it floats a magnetized needle placed on top of a piece of cork will act as a compass. This simple device can also respond to a permanent magnet and show action at a distance. Cork can also be used to seal a flask against low pressure leakage.
How do you pour water down a string?
It is most impossible to pour water down a string unless the string is not a string and is a tube. water can only go down hollow things for heaven's sake!
Can sound waves bounce off gold?
only partially
What is the volume and mass of cork?
That depends on how much cork you have. If you have a large piece, then it will have more volume and more mass. If you only have a tiny piece, then the volume and the mass will both be very small. The volume and the mass will always change together like that, in the same direction. The only thing you can always be sure of is that no matter what size piece of cork you have, the grams of mass will always be about 0.2 times the volume in cubic centimeters.
Water waves can move a piece of cork floating on top of the water only in a up and down motion?
True
Is cork a porous materials?
No. Cork floats because it is not only lighter than water, it doesn't absorb water. That's why cork is used to seal wine and champagne bottles.
Why cork floats in water?
Any object placed in water will be pulled down into the liquid by gravity. But an object less dense than water will only be pulled down until the object displaces an amount of water equal to its own mass. Then it will float. The water will be pushing up equal to the force of gravity pulling down - an equilibrium. Any object that weighs less than its own volume of water will float. It's lower overall density will result in buoyancy.
Do you have to lay wine down?
Only if it has a cork (made of cork wood). Laying it down keeps the cork wet so it doesn't dry out and let air in. If the wine has a screw top then it's fine to stand upright.
What counties in Ireland have only four letters in their name?
Down, Cork and Mayo.
Will a cork float in the center of water?
Only if the beaker is very full and the surface is rounded. Otherwise, the cork will float to the edge of the container (which is typically the highest part of the water).
Explain the method to find the volume of a cork floating in water?
Step 1: Fill a graduated cylinder with water Step 2: Measure how much water is in the cylinder Step 3: Place the cork in the water Step 4: Measure the amount of water again Step 5: Subtract amount of water without cork and amount of water with cork regular- cork = volume of cork This method is called water displacement.
What are the major cirties in County Cork Ireland?
Cork is the only city in the county of Cork. There are many large towns, but only one city.
Why does a cork flaoting on water only bob up and down instead of changing location as a water moves past?
If the water is flowing, like in a river or stream, then the cork goes with the flow. But if it's in a pond, and ripples are rippling out and getting bigger but the cork is just bobbing up and down, then you have learned something very important about transverse waves: The material in transverse waves, like the water in the ripples, or the ground in a seismic surface wave, or the wave in the rope when you snap one end, just moves back and forth across the line of the wave's progress. But although energy is carried along, the material stays where it is and just bobs across the line.
Do all balls bounce and why?
All balls will bounce based on the surface you bounce it on. Even a bowling ball will bounce at least a centimeter or half a centimeter even though it is hard to determine whether it is getting off the ground or not. Of course it wont bounce if you bounce it on something soft and break through, but it will bounce on a hard cement floor. It will bounce because it will have potential energy weighing it down and if the floor is harder than the ball, the ball will move off like opposite sides of a magnet. but only for a while until our gravity pulls it down and stops it. Hope that helped.
How does cork acts as a protective tissue?
Cork is an external, secondary tissue that is impermeable to water and gases, and is also called the phellem. The cork is produced by the Cork cambium which is a layer of meristematically active cells which serve as a lateral meristem for the periderm. The cork cambium, which is also called the phellogen, is normally only one cell layer thick and it divides periclinally to the outside producing cork. The phelloderm, which is not always present in all barks, is a layer of cells formed by and interior to the cork cambium. Together, the phellem (cork), phellogen (cork cambium) and phelloderm constitute the periderm. Cork cell walls contain suberin, a waxy substance which protects the stem against water loss, the invasion of insects into the stem, and prevents infections by bacteria and fungal spores.
Is Cork Airport far from Cork city?
No. It is only about 4 miles or 6.5 kilometres from it.
