Explain why common "contact forces" such as a person pushing on a wall are actually caused by the electric force. In your answer, you must discuss the role of subatomic particles in this interaction, whether the atoms in the person’s hand and the wall come into contact or not

are due to the fact that the electrons that are in one of the objects get close to electrons that are in the other object and since it has the same charge, inte

Explanation:

The contact forces, such as friction or the push force, are due to the fact that the electrons that are in one of the objects get close to electrons that are in the other object and since it has the same charge, intense repuesive forces are formed that objects move. We can see that in these forces the electrons are still attached to the material and only electoral repulsion is what creates the force.

In the previous explanation, it is valid for all types of material, the only change occurs due to the strength of the bond, in the case of materials with free electrons, such as metals, the forces are small, so the sliding occurs for small bourgeois

In insulating materials such as rubber where the electronons are tightly bound, closer proximity is needed to move the electrons from their equilibrium position.

the answer would be 32*f

we have been given a quadratic function and we need to restrict the domain such that it becomes a one to one function.

we know that vertex of this quadratic function occurs at (5,2).

further, we know that range of this function is .

if we restrict the domain of this function to either or , it will become one to one function.

let us know find its inverse.

upon interchanging x and y, we get:

let us now solve this function for y.

hence, the inverse function would be if we restrict the domain of original function to and the inverse function would be if we restrict the domain to .
