At the top of the arc, all of the energy is potential. Potential energy decreases as it comes down and kinetic energy increases, potential energy is 0 at the bottom of the arc and kinetic energy is at its max. Then potential energy increases and kinetic energy decreases as it goes up, and the top of the arc is the same as it was before. I'm not sure if that was the "order" you were looking for but it's my best shot. :)
Answer:
Explanation:
Due to Coulomb´s law electric force can be described by the formula , where K is the Coulomb´s constant (), = Charge 1 (Na+ in this case), is the charge 2 (Cl-) and r is the distance between both charges.
Work made by a force is W=F.d and total work produced is the change in energy between final and initial state. this is .
so we have
Given that ri= 1.1nm= and rf= infinite distance
Burning, cooking
Explanation:
Chemical changes that happens in school are:
Cooking of meals
Burning of wastes
Chemical reactions in laboratories
Rusting of iron used in construction
- A chemical change is a change that produces new kinds of substances.
- These changes are usually accompanied by energy and mass changes.
- Most of such changes are not reversible.
Chemical changes are driven by change in chemical properties of matter.
In a school, iron components might begin to rust. This is a chemical change.

In a food chain we arrange the energy in the form of a pyramid.
The producers are on the base of pyramid and then consumers are towards peak.
in the given food chain grass is being eaten by grasshopper which are food of birds.
Grasshoppers are also eaten up by Hawks. so both brids and hawks are feeding upon grasshoppers thus the amount of energy transferred from the grass to the grasshopper is the same as the amount of energy transferred from the grasshopper to the bird.
The answer is B. It has 8 protons
