What else can I help you with?
How do you make this sentence correct A covalent bond is the force of attraction between the opposite charges of the ions in an ionic compound?
To correct the sentence, you can say: "A covalent bond is the sharing of electrons between atoms in a molecule, whereas the force of attraction between oppositely charged ions in an ionic compound is called an ionic bond."
How do you say you smell in Chinese?
In Chinese, you can say "你闻起来" (nǐ wén qǐ lái) to mean "you smell."
What is the charge on a piece of rubbed amber?
Friction strips electrons so the rubbed amber would take on a negative charge. Actually, friction causes charges to shift. Charges are indeed stripped from something, but they are collected up by something else. Amber does, indeed, become negatively charged by rubbing it with, say, fur. The phenomon is called triboelectric effect. And a link is provided.
What is the force that holds a nucleus of an atom together?
The nuclear force or nuclear binding energy holds an atomic nucleus together. (Some science teachers insist it's called the strong nuclear force, which is not quite correct.)Nuclear binding energy is this nuclear force that overcomes the repulsive electrostatic force of the protons, which is trying to push the nucleus apart. The nuclear binding energy is created from what is called mass deficit. When an atomic nucleus is fused, all the protons and neutrons in that nucleus give up a small amount of their mass, and this mass is converted into the binding energy that holds the nucleus together. And if you guessed that an atomic nucleus has less mass than the sum of the masses of its constituent protons and neutrons, the nucleons, you would be correct.We sometimes call the binding energy nuclear glue, and it is derived from the stong nuclear force or strong interaction. That also gives rise to another term used for nuclear binding energy, and that is residual strong force. The reason we say that nuclear binding energy is derived from the strong interaction is that the stong interaction actually holds individual protons and neutrons together. It is the strong interaction that binds quarks and gluons together into individual protons and neutrons. And it is in nuclear fusion that the strong interaction mediates the creation of the binding energy to hold a newly fused nucleus together.Answer: Nuclear binding energy or residual strong forceWe know protons are all positively charged, and a fundamental law of electrostatics is that like charges repel. But under extreme conditions, nuclear fusion can occur. Positive charges are forced together with neutrons, and all of the particles undergo changes. Each particle gives up a small amount of mass, and this mass is converted in to nuclear binding energy or nuclear glue. And it is this nuclear glue, what is called the residual strong force, that overcomes the repulsion between the protons and binds all the particles in the nucleus together.At the extremely small distances between the protons, the binding energy is greater than the electrostatic repulsion trying to force the protons apart. This is true for elements up to those at the upper end of the periodic table. The heaviest elements experience instability because of the large numbers of protons in their nuclei, and for the heaviest elements, there is no way a "permanent" nuclear arrangement can be made. The residual strong force cannot act across these large nuclei to make them stable, and they exhibit nuclear instability. This results in them being subject to radioactive decay.It is not entirely correct to say that the strong force holds atomic nuclei together, as the strong force (strong interaction) actually holds individual protons and neutrons together. It does this by tightly binding the quarks and gluons that make them up. It is the residual strong force that holds atomic nuclei together. That is the source (through mass deficit) that creates the nuclear binding energy or nuclear glue that acts to oppose the electrostatic repulsion of the protons. You might be aware that the strong nuclear force, along with the weak nuclear force, the electromagnetic force, and gravity, are the four fundamental forces in the universe.It is called, appropriately enough, the nuclear force.It goes by several names: strong force, strong nuclear force, and color force. They're all describing the same thing.Strictly speaking, the strong force is what holds quarks together in a hadron. The force that holds hadrons together is the residual color force.the strong nuclear force is created between nucleons by the exchange of perticles called mesons (changeless particles hadrons made up of one quark and one antiquark).as long as the meson can happen,the strong nuclear force is able to hold the participating nucleons togetherThe nucleus is held together by the strong forceThe electrons are held in the atom by the electromagnetic forceProtons and neutrons are held together in the nucleus by the nuclear force, also known as the residual strong atomic force, also known as residual binding energy.Strong atomic force (binding energy) holds quarks together to form protons and neutrons. It is the strongest force in the universe, followed by a factor of about 100 by the electromagnetic force, and then by many orders of magnitude by the weak atomic force, and then by many many orders of magnitude by gravity. Since it is stronger than the electromagnetic force, it easily overcomes the tendency of the up quark (charge +2/3) and down quark (charge -1/3) to repel each other.Of course, all of this is a function of distance, so gravity has the most effect, when you consider distance, but in the range of a single proton or neutron, the strong atomic force is king.What is left over from holding quarks together is called residual binding energy, or simply, the nuclear force. The nuclear force holds protons and neutrons together. While less than the force of binding energy, it is still more powerful than the electromagnetic force, so the protons with a charge of +1, though tending to repel each other, still stick to each other.Well, its not quite that simple...In the distance of a proton or a neutron, there is no question about strength but, beyond that, the nuclear force degrades with distance, as does the electromagnetic force. Interestingly the nuclear force degrades faster than the electromagnetic force...The ramification of this is that, for smaller nuclei, with exceptions noted below, the nuclear force wins out over the electromagnetic force, and the nucleus is stable. This holds true up to atomic number 82 - iron. Starting at atomic number 83 - bismuth - the electromagnetic force starts to win out over the nuclear force, simply because of the size of the nucleus, and the nucleus becomes unstable. As a result, no nuclide starting at bismuth and up is stable - they are all radioactive, while most nuclides from iron on down are stable.The exception, as promised, is that we still have the issue of proton to neutron balance. It turns out that there is an ideal configuration, based on many things, which is beyond the scope of this question. Suffice to say that 80 of the first 82 elements, from hydrogen to lead, excluding technetium and promethium, have at least one stable isotope.In an atomic nucleus, protons and neutrons are held in together by what is officially known as the strong nuclear force. The exchange particle by which this force manifests itself is the pi meson.
Does Gold Electroplate fade in color?
It doesn't "fade" per say. Rather the electroplating wears off from rubbing against the wearer's skin. As a result it reveals the base metal underneath. So it will slowly turn to a silver color where it experiences the most friction.
What is the force that opposes motion?
Friction.Called inertia. To accelerate a body the force is mass times acceleration. No force = no acceleration. People say " the force is opposed by the massacceleration"
Kinetic frictions is the frictional force needed to start an object at rest into motion?
false. Kinetic friction is the friction acting upon a moving object. It would be the frictional force against you if you pulled a box across a table. Static friction is the frictional force needed to overcome to get an object at rest into motion.
What is the word for a force that opposes the motion of an object?
The opposing forces such as friction in case of solids and viscous force in case of fluids are always present in the natural world.a force can cause a resting object to move, or it can accelerate a moving object by changing the object's speed or direction.in a shorter way to say is frictionFriction
Does static or sliding friction keeps an object from moving when a force is applied?
Static friction keeps an object from moving when a force is applied. It is the force that must be overcome to initiate movement of an object. Sliding friction occurs once the object is in motion.
How does gravity impact friction?
With a fixed mass, if you say double the acceleration due to gravity, you would have to double the force to overcome friction.
The force that opposes the motion of an object?
Gravity. The inertia of an object will keep it moving until an opposing force stops it.Friction.Called inertia. To accelerate a body the force is mass times acceleration. No force = no acceleration. People say " the force is opposed by the massacceleration"
What is the force you have to overcome to start an object moving called?
I have to guess either gravity or friction.If by that you mean a force that opposes the start of motion, then your force would be static friction.Static friction only occurs before an object starts moving, as opposed to kinetic friction which occurs when the objects is moving or sliding. The equation for static friction is: Ff = (coefficient of static friction) * FNInertia
What friction is used when an object sits still?
Static friction is the type of friction that occurs when an object is at rest and prevents it from moving. It arises due to the interlocking of microscopic rough surfaces of the object and the surface it rests on.
How do mass and surface type affect friction?
Mass affects friction by increasing the normal force between the surfaces, which in turn increases the frictional force. Surface type affects friction by altering the coefficient of friction between the surfaces - rougher surfaces typically have higher coefficients of friction which results in greater frictional forces.
How will the coefficients of friction vary if you place standard mass on top?
It won't. Coeffecient of friction is based on the two materials involved (or more, e.g., if a lubricant is used) not on the mass placed on top. We can specify a coefficient of friction for, say, rubber sliding across concrete without ever saying HOW MUCH rubber slides across concrete. If we want to know FORCE of friction, then this is a different story. The force is based on the mass that's on top. On a flat surface, the force of friction equals the coefficient of friction times the weight of the object being dragged. The mass you are talking about would be included in calculating the force, but not in determining the coefficient of friction.
When you say work is done against a force you mean the force does?
Negative work
What is Friction Force?
YES, YEA it is Yes it is a force. If not then we would be slipping around. What i have heard is that friction causes a pull in some ways. Say you slid a pencil on the floor with nothing in it's path. Now if you know what inetia (not a force) then you would know that the pencil would stop because of a outside force. And that force is friction. Friction had reduced the pencils speed when it rubbed together on the floor. Now if the pencil was givin more force when you pushed it and the floor was more slik then the pencil would have traveled alot more. This is because the force of friction is a less amount when one surface is smoother. I know this is a horrible explanation but this is what helps me think of the forces. And this is going to prove to my teacher that friction is a force and that inertia is not.
