Explanation:
Activation energy and reaction rate
The activation energy of a chemical reaction is closely related to its rate. Specifically, the higher the activation energy, the slower the chemical reaction will be. ... The released energy helps other fuel molecules get over the energy barrier as well, leading to a chain reaction.
The correct answer is C. Splitting Nuclei.
Splitting nuclei is not a characteristics of chemical energy.
Chemical energy is termed as the energy which results when there is chemical reaction. Chemical energy is being stored in molecules which makes substance and bonds of atoms.
In order for our bodies to function well they need chemical energy. During photosynthesis plants perform chemical reaction each and every day.
The formula for accelerational displacement is at^2/2, so we know that 3.9t^2/2 = 200, or 3.9t^2 = 400. t =

, at = v, so
Answer:
Explanation:
The total charge in the disks

must be conserved before and after bringing them together.
Lets equate the sum of the initial charge with the sum of the final for the disk:


So, the initial charges must sum +17 μC.
Now, as there are no charges over +17 μC, this means that both charges must be positive.
As the only positive charges are
and
, this disk must be the ones we are looking for. And, as we can see, they sum 17 μC:

Answer:
The environmental problems directly related to energy production and Electricity is a secondary energy source that is generated producedfrom primary energy sources:
hope that helps im new so have a good day (:
