What happens to rubber band Brainly?
Answer: when streched, it changes its shape and when the applied force is removed, it regains its original shapes.
What happens to a rubber band?
In nature, a rubber band is an elastic substance. It changes shape when extended and returns to its original shape when the applied force is withdrawn. That is why, after being a solid, a rubber band changes shape. Furthermore, if too much stress is applied, the rubber band will snap.
What happens to the rubber band what happens to the box attached to the rubber band?
Explanation: It’s just like a strong earthquake happened. The box represents the land and pulling the rubber band attached to box represents the earthquake. The earthquake break the land into 2 that’s causes many damages to the community nearby.
Why do rubber bands contract when heated instead of expanding Brainly?
By heating it up, we increase the entropy. So by heating the rubber band up, we increase the entropy – the amount of disorder among its molecules – and we make it pull itself tighter together. That’s why a rubber band contracts when you heat it up.
What did the plucking of rubber band produce?
When the rubber bands are plucked in order, from thinnest to thickest, the sound will gradually change from a high pitch to a low pitch. The length of the rubber band that is able to vibrate becomes shorter. The shorter bands will vibrate faster, producing a higher pitch.
What is the relationship between faults and earthquakes Brainly?
Explanation: Earthquakes occur on faults – strike-slip earthquakes occur on strike-slip faults, normal earthquakes occur on normal faults, and thrust earthquakes occur on thrust or reverse faults. When an earthquake occurs on one of these faults, the rock on one side of the fault slips with respect to the other.
What happen when you stretch the rubber band?
A rubber band is an elastic material in nature. When stretched, it changes its shape and when the applied force is removed, it regains its original shape. That is why a rubber band changes its shape even though it is a solid. Also, if excessive force is applied then the rubber band would break.
Why does a rubber band break after using it many times?
In natural rubber, oxygen exposure will begin to break down the double bonds within days, leaving a crumbly mess; that is why rubber has been heated and treated for thousands of years – to slow the inevitable breakdown.
What will happen if you stretch a rubber band?
You input potential (stored) energy into the rubber band system when you stretched the rubber band back. Because it is an elastic system, this kind of potential energy is specifically called elastic potential energy.
Can you make a sound using a rubber band without making it move?
You can`t produce a sound without making something move. If you pluck a rubber band, the rubber band moving back and forth produces twanging sounds. Unless something vibrates , there can be no sound. A vibration that spreads away from a vibrating object is a sound wave.
Are there changes in the note when you plucked the stretch band?
Yes. there are changes in the note when you the stretched band plucked.
Does increasing the number of rubber band effect the pitch produced in the sounding box?
The thickness of the rubber band changed the tone of the sound you heard when you plucked it. The thinner strings on a guitar make a higher-pitch sound because they can vibrate more quickly than the thicker ones.
Does rubber shrink when heated?
The rubber band actually expands when it gets colder! This occurs because of the unusual polymer structure of rubber. When the long chains get hotter and vibrate, they actually shorten, causing the material to contract. When the chains cool down, they relax and stretch out, causing the material to expand.
At what temperature does rubber expand?
Polymers like rubber shrink on heating as their molecular chains curl up, and water shrinks when warmed from its freezing point to around 4°C. After that, though, it behaves normally, and expands on warming.
Do rubber bands melt in boiling water?
Here’s the rub: the problem with rubber bands is that they are not designed to withstand the temperature of boiling water. “Since the boiling point of water is 212 F, there could possibly be some deterioration of the rubber.”Jun 29, 2011.
How do you describe the movement of the rubber band when plucked fast?
Answer: When plucked, a stretched rubber band will vibrate at its resonant frequency. Different rubber bands will produce different resonant frequencies, depending on their thickness or width, and how tightly they are stretched.
Which rubber band produced a higher sound?
Thicker, heavier, and loosely stretched rubber bands will sound lower pitched, while thinner, lighter, tightly stretched rubber bands will sound higher.
Does the thickness of a rubber band affect how far it stretches?
Yes, the thickness does affect the distance because rubber bands that are thick are harder to stretch then a thin rubber band. Rubber bands that are thicker are harder to stretch, which in my prediction might have a shorter distance.
What is a fault line in geology?
A fault is a fracture or zone of fractures between two blocks of rock. Faults allow the blocks to move relative to each other. This movement may occur rapidly, in the form of an earthquake – or may occur slowly, in the form of creep. Most faults produce repeated displacements over geologic time.
How strong is the earthquake?
Earthquake Magnitude Scale Magnitude Earthquake Effects Estimated Number Each Year 2.5 to 5.4 Often felt, but only causes minor damage. 500,000 5.5 to 6.0 Slight damage to buildings and other structures. 350 6.1 to 6.9 May cause a lot of damage in very populated areas. 100 7.0 to 7.9 Major earthquake. Serious damage. 10-15.
Does an unstretched rubber band have energy?
Therefore in the unstretched rubber, energy is much spread out — as is indicated by its high entropy. In contrast, when a rubber band is pulled, its enormous number of lengthy molecules are stretched out and there is less opportunity for free rotation or bending in these conformations.
Does a rubber band stretch when weight is applied?
If you get hold of a rubber band and pull it you are using a force on it. That force makes the rubber band get longer – it stretches. The greater the pull the longer it gets. In other words a bigger force makes the rubber band stretch more.
Why does rubber band heat up when stretched?
When molecules, not just rubber molecules, but any molecules, form crystals, they give off heat. This is why the rubber band feels hot when its stretched. When you let go of the rubber band, the polymer molecules break out of those crystals. Whenever molecules break out of crystals, they absorb heat.
