Why does glass break into many small pieces?
Glass breaks into small pieces due to its internal stress. When a force is applied to glass, it overcomes the tensile strength of the material, causing it to break. The internal stress causes the glass to shatter into small, uniform pieces to reduce the potential for injury.
What is Ampere's swimming rule?
If we imagine a man is swimming along the wire in the direction of current with his face always turned towards the needle ,so that the current enters trough his feet and leaves at his head, then the north pole of magnetic needle will be deflected towards his left hand .this rule can be recollected with the help of the word snow..
snow - current flowing from south to north over magnetic field then deflection of compass or needle is towards west..
Why doesn't the ice-cream melt in baked Alaska?
The meringue layer on a baked Alaska acts as an insulator, which helps protect the ice cream from melting when briefly exposed to high heat in the oven. The meringue layer helps to keep the cold temperature inside the dessert while the outside browns.
Toni's average speed is 15 km h-1.
As we measured her travel distance over one sixth of an hour, her speed in km h-1 is (6 X 2.5) km h-1
In phsics dont you have to change it so its meters of seconds?
How can you change the pitch produced by a vibrating string?
To raise the pitch (frequency), put more tension on one end of the string. To lower the pitch, put less tension on one end of the string. For instance, on a guitar, tighten the string for a higher pitch. Loosen the string for a lower pitch. Additionally, if you have a guitar string already mounted and tensioned. You may place your finger in the middle of the string, and the pitch will go up one octave. Each time you halve a tensioned string, it produces a pitch one octave higher.
Discovery and date of the element Aluminum?
Aluminum was discovered by Hans Christian Oersted in 1825 in Denmark.
What are the different parts of waves?
for me I BELIEVE IN THE SAYING THAT "EVERY FILIPINO DESERVE IT" I THANK YOU
What is the units for kinetic energy?
kinetic energy like any other form of energy , its measuring units are joule or calorie or Btu or toe , the most common used units are joule and calorie according to what field you are using kinetic energy in , in thermodynamics we use calorie but in oscillations and waves we use joules
What does the statement a high equilibrium product constant mean?
A high equilibrium product constant indicates a higher concentration of products at equilibrium compared to reactants in a chemical reaction. This suggests that the reaction strongly favors product formation under the given conditions.
How many kilojoules in a kilogram?
It depends on the materia. 1 kg fat contains more calories (joule) than 1 kg water
Does foil conduct electricity?
Yes, foil can conduct electricity due to its metallic properties. The metal composition in foil allows it to serve as a conductor of electricity, making it useful for various applications like wrapping electrical wires or creating makeshift circuits.
A wave is disturbance or oscillation, that travels through matter (eg mechanical waves) or space (eg electromagnetic waves) accompanied by a transfer of energy. A wave can be transverse or longitudinal, depending on the direction of its oscillation.
A single definition for the term WAVE is not straightforward. However waves have
- A direction,
- A velocity,
- An amplitude,
- A wavelength.
- A waveform
----------------------------------------------------------------------------------------------------------
Parts of a Wave Transverse Wave For a transverse wave, there are five main parts that make up the wave. They are: the equilibrium or rest position, the crest, the trough, the amplitude, and the wavelength. The equilibrium or rest position is the imaginary line that represents where the string (for example) would assume if there was no wave traveling through it. The crest is the point on the wave that has the greatest positive displacement from the equilibrium or rest position. The trough is the point on the wave that has the greatest negative displacement from the equilibrium or rest position. The amplitude of a wave is the distance from the crest, or trough to the rest position. It is the maximum amount of displacement that the wave has. The wavelength of a wave is the length of one complete wave cycle. This means, the length from crest to crest or tough to trough, from the rest position over a crest and trough and back to the rest position, or any two other point that are one complete wave cycle. Longitudinal Wave For a longitudinal wave, there are three main parts that make up a wave. They are: the compression, the rarefaction, and the wavelength. Since the particles of a longitudinal wave are vibrating and moving in line with the wave, there are areas where the coils (of a slinky, for example) are closer together. These areas are called compression's. The areas where the coils are spaced out more are called rarefaction's. The wavelength for a longitudinal wave is very similar to that of a transverse wave. It is still the length of one complete wave cycle, but instead of it being from crest to crest, it is from compression to compression, or rarefaction to rarefaction, or any two other points that are at the same point on the wave cycle.
Diffrence between conductor and insulator?
A conductor is a material that allows electric current to flow through it easily, such as metals. An insulator is a material that does not allow electric current to flow through it easily, such as rubber or glass. Conductors have free-moving electrons, while insulators have tightly bound electrons.
The number of inputs in an OR gate can vary, but the most common type is a 2-input OR gate. This means that it takes two input signals and produces one output signal based on the logical OR operation.
Roof tiles follow a corrugated design to keep water from pooling under the tiles. If water gets under the tiles, it could damage the roof, the interior of the house and possible the entire structure.
Why does shredded paper feel lighter to carry than the same amount of paper that is not shredded?
Shredding does not change the weight of a piece of paper, and I suspect that the sensation of it is a sensory illusion. Over time and with experience, our minds tend to learn to approximate weights of things based on vision, and since shredded paper takes up much more space than unshredded, we thus "expect" it to weigh more, although its weight has not changed because of the shredding.
What is the definition of conductors and insulators?
Conductors are materials that allow the flow of electrical current, as they have loosely bound electrons that can move freely. Insulators, on the other hand, are materials that do not allow the flow of electrical current, as their electrons are tightly bound and cannot move easily.
When does Sound travels fastest through matter when it is warm cold or not moving?
It depends... It's well-known that sound travels faster through denser (cold air has higher density then warm) media. So if you have a situation when sound travels through either cold or warm air. The speed of the sound will higher in the cold air.
From other side if you have air which of course possesses certain temperature which is moving the sound speed will depend on both temperature and the vector of velocity (direction where it is blowing and and value how much it's blowing).
What does it mean to say that a material has a high or low specific heat capacity?
The specific heat capacity of a substance is the amount of energy required to increase the temperature of a said substance 1o K. The capacity is measured in kilojoules divided by kilogram time degrees Kelvin (kJ/Kg k). So, if the specific heat capacity of a substance is high, it requires a very large amount of energy to increase the temperature, and if it has a low specific heat capacity, the required energy will be lower.
Why do insulators not conduct electricity?
The fundamental difference between a conductor and an insulator is that some electrons of the atoms of a conductor are not stuck to specific atoms but are free to move throughout the material. For insulators, the electrons are tightly bound to the specific atoms or in the chemical bonds between atoms. A relatively small force created by the electric field due to an applied voltage produces a tremendous movement of the nearly free electrons in a metal and almost no response at all from tightly bound electrons in an insulator.
Longer Answer:
For a material to carry electricity, it must contain charge carriers that move.
In metals, the outermost electrons of the atoms are not localized on the atoms, but extend far out into the material and are often termed delocalized. This is a way of saying that electrons in metals are essentially free to move throughout the material. As a consequence, little or no energy is required to transport electrons through a metal. Metals are thus good conductors of electricity.
Materials that are insulators have electrons that are localized on specific atoms or localized in particular chemical bonds that join atoms. To move an electron from one atom to the next requires some energy to initially dislodge it. On the atomic scale, the electric field to dislodge an electron from one atom and move it to a nearby atom is typically very large for materials that are not metals. As a result, most materials are insulators.
Finally, it is worth pointing out that ionic liquids, like salt water, conduct electricity not as moving electrons but as a consequence of the movement of charged atoms, e.g. Na+ and Cl-. Conversely, a solution of sugar does not ionize and the molecules are not charged, so conductivity is nearly zero.
Caveat: For the expert, the ultimate quantitative answer to this question requires discussing quantum theory of electrons in solids and band structure and impurities and defects and lattice vibrations.
Will the titanium plates and screws in your face cause bad reception while using a cell phone?
Titanium plates and screws in your face should not cause bad reception while using a cell phone. Metal implants do not significantly interfere with radiofrequency signals used by cell phones. If you experience any issues, it is more likely due to other factors such as signal strength or phone software.
Why do liquid conducts electricity?
- the liquid could be a metal such as mercury or gallium.
- the liquid could be a polar solvent such as water and contain ions
- any surface whether it be a solid or a liquid will conduct an AC current.
How Do Glass Break By Singing?
Glass can break when exposed to certain frequencies, such as those produced by a singer with a very strong and sustained voice. If the pitch of the sound waves matches the natural frequency of the glass, it can cause the glass to vibrate excessively and ultimately shatter due to this resonance phenomenon.
What would be the height of highest building ever possible?
The only thing that will be able to determine the height of the highest building ever built will be how strong we can make a foundation for it, if it is too tall the steel supports of the building will collapse or the foundation (made of concrete) will rupture or crack, making the building fall. So it really all about how strong mankind can make the foundation. Apart from strong foundations there are more challenges a high rise faces e.g. The swaying of the building due to wind pressure. We will have to face the Jet Streams.
Temperature changes.
Ability to lift the raw materials to such a height (in case its a RCC structure, one would need enormous pump sets to supply the RCC at that height. Check the Burj Dubai structure for this.).
