How is a conducter different from an insulater

A conducter will allow electricity to flow through it. An insulator cannot conduct electricity.

Condutor is a Material which permits the electric current or heat to pass through it.

insulater a substance which does not readily allow the passage of heat or sound.        

Thermal Conductivity of conducter is High.  

Thermal Conductivity  of insulater is low.  

conducter Covalent bond  is Weak.    

insulater  Covalent bond  is  Strong.  

conducter  electrons will freely move.

insulater electrons will not freely move.

note: the given question is incomplete.

complete question is given below.

which is an example of kinetic energy?

a. the energy stored in ethanol  

b. a hockey puck sliding across the ice  

c. a compressed spring  

d. a ball sitting at the top of a ramp

solution: the kinetic energy is the energy posses by the virtue of the motion of the object.

in the given options, a, c and d are the example of potential energy because it is the energy posses by the virtue of the rest of the object. but option b has the kinetic energy as the object is in motion.

hence, a hockey puck sliding across the ice   is the apex example of kinetic energy.

so, the option (b) a hockey puck sliding across the ice   is the correct option.

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 .
