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.
Exothermic because exothermic reactions transfer energy to the surroundings. Endothermic reactions take in energy from the surroundings, so if you want to warms people's hands you should use exothermic chemical reaction for the product.
The running speed of Jenny willl be 2.5 times the velocity she walks.
<h3 /><h3>What is velocity?</h3>
The change of distance concerning to time is defined as speed. Speed is a scalar quantity. It is a time-based component. Its unit is m/sec.
Condition 1;
She takes 25 minutes to run 1,000 m and walk 1,600 m The total time to run as well as the walk is 25 minutes.

As we know that;
Distance = speed × time

For walking;


Same as for condition 2;


Condition 3;



Hence their running speed of Jenny willl be 2.5 times the velocity at she walks.
