North magnets attract the opposite side in this case south would attract to north and vise versa if it was negative it would attract to positive and vise versa
I don't know what you are talking about but if you are asking about the difference between <span>electric discharge and electric current then;</span>
The electric current is the amount of electrons or charges passing through a conductor per units of time. 1 ampere = 1 coulombs / 1 second.
Electric discharge is the consequence of disrupting an isolator (for example, air), thus causing a sudden flow of electricity.
Answer:
The correct answer is C) insulator
Explanation:
The characteristics of metals consist of conductivity (for example of heat), malleability (deformation property) and ductility (stretching capacity).
Answer : The correct option is C.
Explanation :
Enthalpy of reaction : It is defined as the changes in heat energy takes place when reactants go to products. It is denotes as 
.
= Energy of product - Energy of reactant
is positive when heat is absorbed and the reaction is endothermic.
is negative when heat is released and the reaction is exothermic.
In the given potential energy diagram, the energy of product at higher level and energy of reactant at lower level. The for this reaction will be positive.
So, the enthalpy of reaction is defined as the difference of the energy of the reactants and the energy of the products.
